Intravenous Lidocaine for Hepatectomy
Liver resection is increasingly performed for hepatic tumors, mainly primary liver cancers and resectable metastases, but also for some benign lesions. Postoperative pain is often significant, regardless of the surgical technique, making effective pain control essential to promote early mobilization and reduce complications. Current standard care relies on multimodal analgesia, combining several drugs administered during surgery, with morphine administered as rescue therapy when required. Morphine is associated with side effects such as nausea, vomiting, ileus, hypoxemia, opioid-induced hyperalgesia, and transient cognitive impairment. Therefore, there is a need to optimize pain management while reducing opioid consumption and related adverse effects. Intravenous (IV) lidocaine has well-documented anti-inflammatory effects and is effective against neuropathic pain. Several studies have shown that intravenous lidocaine may be associated with improved analgesia, reduced opioid consumption, shorter hospital stay, and decreased postoperative ileus, nausea, and vomiting-particularly in abdominal and genitourinary surgeries. Therefore, Intravenous (IV) lidocaine may be a valuable alternative for postoperative pain management after liver surgery. National guidelines now recommend perioperative Intravenous (IV) lidocaine for abdominal surgeries but its efficacy in liver surgery has not yet been established due to a lack of specific evidence (more specific data are needed). Findings from other types of abdominal surgery suggest a potential benefit, which should be confirmed by dedicated clinical trials and robust multicenter evaluation such as the ILHEP protocol. The goal of this clinical trial is to assess the effect of intravenous perioperative lidocaine on postoperative opioid related-side effects and to formally confirm the safety of lidocaine during hepatic surgical procedures. The hypothesis is that Intravenous (IV) lidocaine compared with placebo (a look-alike substance that contains no drug e.g. a saline solution) would improve postoperative outcome by reducing opioid related side-effects in patients undergoing liver surgery and benefitting of the same baseline analgesia. In the context of this trial, patients will receive either intravenous lidocaine or placebo according to their assigned randomization group during standardized general anesthesia, and will then be followed throughout their hospital stay until discharge or up to a maximum of 28 days. An ancillary study will be conducted in patients enrolled at the coordinating center in Rennes to assess exposure to lidocaine during intravenous administration and to evaluate the relationship between blood concentrations and adverse events.

The Impact of Perioperative Lidocaine Infusions on Enhanced Recovery After Non-Cardiac Surgery
The goal of this single-center, pragmatic, randomized, blinded, placebo-controlled trial is to evaluate the impact of intravenous (IV) lidocaine within the existing Enhanced Recovery After Surgery (ERAS)program on outcomes in patients after major non-cardiac surgery. The main questions the trial aims to answer are: The primary hypothesis is that utilization of IV lidocaine as part of a perioperative multimodal pain regimen will result in a reduction in hospital Case Mix Index-Adjusted Resource Length of Stay (CARLOS). The secondary hypotheses are that lidocaine infusion will result in a reduction in total inpatient opioid consumption (oral morphine milligram equivalents, oMMEs) and pain scores, and improved surgical outcomes (including return of bowel function, ileus, nausea, rapid responses called, surgical site infections, and ICU transfers), while also having minimal incidence of side effects (including double/blurry vision, tinnitus, sedation, and adverse events requiring early cessation).
Plasma Kinetics of Levobupivacaine After Transversus Abdominis Plane (TAP) Block in Abdominal Surgery
This prospective single-center observational pharmacokinetic study will evaluate plasma levobupivacaine concentrations after ultrasound-guided transversus abdominis plane (TAP) block in adult patients undergoing elective abdominal surgery under general anesthesia at CHU Liège. Participants receiving TAP block as part of standard clinical care (levobupivacaine 0.375%, total volume 40 mL, maximum dose 150 mg) will undergo serial blood sampling at 3, 7, 15, 30, 60, 120, and 180 minutes after block completion. Plasma levobupivacaine concentrations will be measured using validated LC-MS/MS methods. The primary objectives are to estimate maximum plasma concentration (Cmax) and time to maximum concentration (Tmax). Secondary objectives include characterization of the concentration-time profile, AUC0-180, interindividual variability, and exploratory associations with clinical factors (age, sex, BMI, type of surgery). The study also aims to inform a pragmatic safety window for subsequent intravenous lidocaine infusion used in multimodal analgesia protocols. Approximately 26 participants will be enrolled. No modification of routine anesthesia or analgesic care is required apart from study-related blood sampling.

A Clinical Trial on the Use of Lidocaine Infusion During Surgery for Pediatric Upper Extremity Fractures and Its Impact on Total Perioperative Opioid Requirements
This study is a prospective, randomized, double-blind clinical trial evaluating whether intraoperative intravenous lidocaine infusion (IVLI) reduces opioid requirements and improves postoperative pain control in children undergoing surgical fixation of upper extremity long bone fractures under general anesthesia. Ninety pediatric patients, ages 3-18 will be enrolled and randomized 1:1 to receive either IV lidocaine or placebo (normal saline) during surgery. All participants will receive standardized anesthesia care and postoperative pain management. Opioid consumption and pain scores will be measured intraoperatively and throughout the postoperative recovery, with the primary outcome focused on total opioid use 60 minutes after arrival to the post-anesthesia care unit (PACU). Secondary outcomes include opioid use at additional time points, postoperative pain scores, PACU length of stay, rescue antiemetic use and the relationship between infusion duration and outcomes. Patients will be closely monitored for signs of local anesthetic systemic toxicity and other adverse events. The goal of this study is to determine whether IV lidocaine is an effective opioid-sparing adjunct in pediatric orthopedic surgery and to support safer, multimodal analgesia strategies.

This study will assess the efficacy, safety and practicality of using midline catheters for repeated intravenous lidocaine infusions in an outpatient pain management setting. Adult patients requiring serial lidocaine infusions for chronic pain will be enrolled and receive treatment through midline catheters over ten sessions. The study will investigate if the midline catheters are a safe and effective option for delivering repeated lidocaine infusions in the outpatient setting, offering a balance between ease of placement, acceptable complication risk and good patients' comfort.
Intravenous Lidocaine Infusion in Lumbar Fusion Surgery
Elective lumbar fusion surgery is associated with moderate to severe postoperative pain and often requires substantial perioperative opioid administration. Excessive opioid use may lead to adverse effects such as nausea, vomiting, sedation, respiratory depression, and delayed mobilization. Intravenous lidocaine infusion has been proposed as part of multimodal analgesia because of its analgesic, antihyperalgesic, and anti-inflammatory properties. This randomized, placebo-controlled clinical trial aims to evaluate the effect of intraoperative intravenous lidocaine infusion on postoperative opioid consumption and early recovery outcomes in patients undergoing elective lumbar fusion surgery. Patients will be randomly assigned to receive either intravenous lidocaine infusion or placebo during surgery. The primary outcome is cumulative postoperative opioid consumption within the first 24 hours after surgery. Secondary outcomes include intraoperative opioid consumption, postoperative pain scores, time to first rescue analgesic, quality of recovery, postoperative nausea and vomiting, time to mobilization, and length of hospital stay. In addition, inflammatory and oxidative stress biomarkers including interleukin-6 (IL-6) and markers of thiol-disulfide homeostasis will be measured preoperatively and postoperatively.

Intravenous Lidocaine Infusion Versus Intravenous Dexmedetomidine Infusion During Sleeve Gastrectomy
Although laparoscopic (LAP) bariatric surgery is minimally invasive. Following any laparoscopic procedure, patients typically experience the peak of postoperative pain within the first 24 hours. This intense pain gradually subsides, with significant relief usually occurring by the 2nd or 3rd postoperative day. The initial peak and subsequent decline in pain intensity highlight the importance of effective early pain management strategies to ensure patient comfort and recovery during this critical period. Inadequate management of postoperative pain can result in serious complications. Lidocaine is increasingly recognised as a vital adjunct in managing perioperative pain. Its efficacy extends beyond traditional local anaesthetic applications, as it also demonstrates analgesic, anti-hyperalgesic, and anti-inflammatory properties. Dexmedetomidine is a highly selective alpha-2 adrenergic agonist with hypnotic, sedative, anxiolytic, sympatholytic, and analgesic effects, while causing minimal respiratory depression

IV Lidocaine Infusion Versus Placebo for Pain Control in Staging Laparoscopy Cases
IV lidocaine infusion is being used as an analgesic adjunct, since we are a opioid depleted country we are using lidocaine to decrease opioid consumption and avoid the side effects such nausea, vomiting and respiratory depression associated with morphine consumption. We have given the option of rescue analgesia to the anesthetist if the clinical scenario demands.
Effect of Lidocaine-Dexmedetomidine on Pain, Inflammation, and Oxidative Stress After Bariatric Surgery.
The goal of this randomized clinical trial is to find out whether giving an intravenous lidocaine + dexmedetomidine combination (LIDEX) during laparoscopic bariatric surgery can lower post-operative pain, inflammation, and oxidative stress in adults with obesity. The main questions it aims to answer are: * Pain control: Does LIDEX reduce pain 24 hours after surgery, as measured with the International Pain Outcomes Questionnaire (IPOQ)? * Biomarkers: Does LIDEX lower blood levels of key inflammatory cytokines-interleukin-1 beta (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and interleukin-10 (IL-10)-and oxidative-stress markers-malondialdehyde (MDA), the reduced/oxidized glutathione ratio (GSH/GSSG), superoxide dismutase (SOD), and catalase-compared with the individual drugs or saline placebo? Researchers will compare four groups: lidocaine alone, dexmedetomidine alone, LIDEX, and placebo (saline solution, a look-alike substance that contains no drug) to learn which approach works best. Participants will: * Receive an intravenous infusion of their assigned study drug(s) during surgery. * Provide three small blood samples (before surgery, immediately after, and three hours after). * Complete a short pain questionnaire (IPOQ) 24 hours after surgery.

Effects of Intravenous Lidocaine Treatment on Sleep and Quality of Life in Fibromyalgia: An Observational Study
Fibromyalgia (FM) is a psychosocial disorder characterized by widespread body pain, sleep disturbances, morning stiffness, and fatigue, impairing patients' quality of life. It is more common in middle-aged women, but its prevalence is 2% in the general population. Genetic factors, peripheral and central sensitization, autonomic nervous system dysfunction, and hypothalamic-pituitary axis dysregulation are thought to play important roles in its pathophysiology. In FM patients, decreased levels of norepinephrine, dopamine, serotonin, and some other neurotransmitters in the central nervous system and cerebrospinal fluid have been observed . Complaints in FM patients vary considerably. The pain often begins localized and progresses to widespread body pain. Physical examination frequently reveals allodynia and hyperalgesia. Irritable bowel syndrome, depression, primary headaches, restless leg syndrome, Reynoud phenomenon, dry mouth, palpitations, allergic conditions, sexual dysfunction, dysmenorrhea, chronic fatigue syndrome, and anxiety disorder may accompany the condition. While these diagnoses are also considered in the differential diagnosis, their presence does not exclude the diagnosis of FM. The 2016 revised American College of Rheumatology (ACR) criteria are frequently used for diagnosis. A multimodal approach is applied to treatment. These approaches include lifestyle changes, exercise, meditation, balneotherapy, yoga, psychotherapies, medical, and interventional methods. Antidepressants are often preferred for medical treatment. Patients' noncompliance with medication and side effects contribute to medical treatment failure. Acupuncture, dry needling, trigger point injections, and some complementary medicine methods are interventional methods . In recent years, particularly in chronic pain management, intravenous (IV) methods are thought to reduce both peripheral and central sensitization. Intravenous drug therapies for chronic pain have been reported to be beneficial in addition to medical and interventional treatments. Magnesium, lidocaine, and ketamine are frequently administered IV treatments. There are various recommendations regarding the frequency and dosage of these medications, but a consensus has not yet emerged. IV lidocaine has been used in FM patients in recent years, although the number of studies reported is limited . The symptom severity and pain prevalence in FM patients vary from patient to patient. Therefore, the treatment approach should be individualized. Sleep and quality of life disturbances frequently accompany FM and exacerbate other symptoms . To our knowledge, IV lidocaine treatment is considered beneficial in FM patients, but we have not found any studies in the literature on its effectiveness on sleep and quality of life. In this study, we aimed to present the effects of IV lidocaine, a less frequently administered but well-established treatment method in FM, a challenging disease.

Intraoperative Continuous Lidocaine Infusion in Laparoscopic Liver Surgery
The goal of this clinical trial is to learn about effect of intraoperative continuous lidocaine infusion on postoperative pain, gut function and insulin resistance in patients undergoing laparoscopic liver surgery in adults. It will also learn about the safety of this infusion in this setting. The main questions it aims to answer are: does the intraoperative continuous systemic lidocaine infusion lower the opioid consumption 24h after surgery? Is the time to first flatus after surgery reduced? Is there increases in insulin resistance after intraoperative lidocaine infusion? Researchers will compare intraoperative continuous systemic lidocaine infusion to a placebo (a look-alike substance that contains no drug, which will be normal saline administered at the same volume, infusion rate and timing) to see if intraoperative continuous systemic lidocaine infusion reduces postoperative pain after laparoscopic liver resection. Participants will receive intraoperative continuous systemic lidocaine infusion or placebo. Clinical assessment will be based on gathering data of NRS scores after the surgery, time to first flatus or stool. How much opioids the patients need in the first 3 postoperative days. Laboratory assessment will include the evaluation of fasting blood glucose concentration and insulin levels preoperatively and on 1, 2 and 3 postoperative days.
Lidocaine Infusion Versus Magnesium Infusion in Decreasing Fentanyl Requirements in Endoscopic Sinus Surgeries
Enhanced recovery after ear, nose and throat surgery is based on multimodal and multidisciplinary perioperative interventions to decrease postoperative pain. Functional endoscopic sinus surgery is a surgical management for chronic rhinosinusitis. Although a common procedure, there is a lack of knowledge about perioperative pain and specific pain management after such a procedure. Most of recommendations given in guidelines for postoperative pain management in nasal surgery and sinus surgery are subsumed under head and neck surgery. Head and neck surgery is a wide field covering widely variable surgical procedures. So, postoperative pain management guidelines may not meet the requirements for pain management during and after endoscopic sinus surgery. Various medications have been used to improve the surgical field and postoperative pain including intravenous clonidine, dexmedetomidine, lidocaine, and magnesium. Lidocaine has been used considering its analgesic, immuno-modulating, and anti-inflammatory properties. The opioid sparing effect of lidocaine is supported by a high level of evidence. The effectiveness of lidocaine infusion in obtaining reduction of postoperative pain, gastrointestinal recovery time, postoperative nausea and vomiting, and shortening the hospital length of stay, was demonstrated principally in major gastro-intestinal surgery. Magnesium sulfate is a good option in multimodal analgesia, as it stabilizes the cell membrane and intracytoplasmic organelles by mediating the activation of Na+-K+ ATPase and Ca++ ATPase enzymes, which have an important role in transmembrane ion exchange during the depolarization and repolarization phases. Moreover, magnesium inhibits the release of norepinephrine by blocking the N-type Ca++ channels at nerve endings. Many studies were designed to prove the role of the analgesic effect of lidocaine and magnesium infusion. However, this is the first randomized controlled study to assess the effect of lidocaine infusion versus magnesium sulphate infusion on decreasing total fentanyl requirements in patients undergoing functional endoscopic sinus surgery. This randomized controlled trial was designed to compare the efficacy of lidocaine hydrochloride infusion versus magnesium sulphate infusion in controlling perioperative pain in patients undergoing functional endoscopic sinus surgery.
Comparing Efficacy of Intravenous Dexmedetomidine and Lidocaine on Postoperative Analgesia in Patients Undergoing Fracture Hip Surgery
Perioperative pain management has been a major challenge for anesthesiologists, and there have been persistent efforts to bring out the best possible analgesic technique with the least side effects. Hip fractures are devastating injuries, constituting a global public health burden and remain one of the largest healthcare challenges of the 21st century. The incidence increases with advancing age and the number of hip fractures is expected to increase to 6.26 million per year in 2050. Hip fractures impact on patient's psychological, functional, and social wellbeing, and account for substantial healthcare system costs. Drugs of potential interest such as intravenous (i.v.) lidocaine and dexmedetomidine have been administered both intra and/or postoperatively to decrease perioperative pain and improve other outcomes. Lidoocaine has analgesic, anti inflammatory, and anti hyperalgesia properties. Several studies have demonstrated that perioperative lidocaine infusion reduces postoperative pain intensity and opioid consumption . Ease of availability, cost effectiveness, simplicity of administration, safety, and analgesic action make lignocaine an attractive option. Dexmedetomidine is a highly selective and specific α2 adrenoceptor agonist with useful analgesic, sedative, anxiolytic, and sympatholytic properties. I.V. dexmedetomidine has gained immense popularity owing to its efficacy as an analgesic adjuvant, translating into reduced opioid consumption. Intraoperative dexmedetomidine and lignocaine also confirm the enhanced recovery after surgery protocol advocating the reduction of opioid use. While numerous studies have analyzed i.v. lidoocaine and dexmedetomidine versus placebo regarding postoperative analgesia and outcomes, researches and evidence in the context of minimally invasive surgeries regarding adverse effect profile, postoperative analgesic requirement, perioperative analgesia, anesthesia recovery, and opioid requirements are always welcome(rephrase). Our study was conducted to analyze the effects of intraoperative i.v. lidocaine and dexmedetomidine on pain relief, intra- and postoperative opioid consumption, and effects of these infusions on intraoperative hemodynamic parameters and to evaluate the side effect profiles the aim of the study to analyze the effects of intraoperative intravenous lignocaine/dexmedetomidine on postoperative pain relief and analgesit consumption
Comparison of Continuous Intravenous Lidocaine Infusion Versus ESP Block for Rib Fracture Analgesia
Recently in 2016, a new interfascial plane nerve block was developed for thoracic analgesia known as the erector spinae plane block (ESPB). Since its development for thoracic neuropathic pain, the ESPB has been shown to be effective in pain control in multiple procedures including thoracotomies. However, there have been a few published case reports of using ESPB for analgesia in rib fracture management and only one retrospective study which demonstrated improved NRS pain scores and increased incentive spirometry volumes (ICV) post-ESPB compared to pre-ESPB values. The goal of this study is to compare the effectiveness of ESPB as an alternative method to the current standard of care at Stanford Health Care (SHC) for pain management in traumatic rib fractures. At the investigator's institution, the current standard of care is intravenous (IV) and enteral multimodal analgesia that consists primarily of opioids and a continuous IV lidocaine infusion. Although IV lidocaine has shown some benefit in improving post-surgical pain scores, evidence for its use in MRF is lacking. The purpose of this study is to perform a randomized clinical trial comparing outcomes in pain control and incentive spirometry volumes between continuous ESPB catheters and IV lidocaine infusions in adult patients with acute traumatic rib fractures. The investigators want to determine if ESPB can provide improved pain control in patients admitted for traumatic rib fractures compared to IV Lidocaine. The aim is to evaluate the clinical effectiveness of ESPB on OME consumption, pain scores, incentive spirometry volumes, cough strength, respiratory complications, inflammatory biomarkers and hospital LOS. Findings from this study can help improve analgesia, quality of care, and patient satisfaction at Stanford Healthcare and for other acute pain and trauma surgery providers. The aim of this study involves pain management for patients with acute traumatic rib fractures and therefore must involve human subjects.
Pharmacokinetic Study of Intravenous Lidocaine in Young and Elderly Patients
Aging is accompanied by a gradual alteration in the functional reserve of several organs and a change in body composition that can affect the pharmacokinetics, response, and safety profile of medications. Lidocaine is a local anesthetic used daily in perineural or intravenous administration to reduce the need for opioids. Although its analgesic efficacy is well-established, there is currently only one older study regarding the pharmacokinetics and pharmacokinetic-pharmacodynamic (PK-PD) relationship of lidocaine in healthy elderly patients. In this study, conducted with a small sample size (13 subjects over 64 years old and 24 young subjects under 38 years old) and using a low bolus of 25 mg, the half-life of lidocaine was increased by 59% and clearance was decreased by 35% in elderly male subjects without significant differences in females. However, the recommendations for intravenous administration of lidocaine for analgesic purposes are the same for all: a bolus of 1 to 2 mg/kg followed by continuous administration of 1.5 to 2 mg/kg/h. Morphine sparing is particularly important in elderly patients due to their increased sensitivity to adverse effects. With this study, the investigators aim to define the optimal dose to administer in elderly subjects, in order to optimize analgesia while remaining within the therapeutic range to limit the adverse effects of lidocaine.

It also aims to evaluate the impact of both medications on intraoperative regional cerebral oxygen saturation (rSO₂).
Perioperative Lidocaine Infusions for the Management of Pain From Burn Injury
The purpose of this study is to find out if IV lidocaine infusion decreases the need of opioids, improves pain management, and reduces the risks of developing complications from prolonged opioid use in burn injury participants undergoing wound debridement in the operating room. Participants will: * be randomized to receive either an IV Lidocaine treatment or an IV Saline Placebo during their surgery. The IV treatment continues for 48 hours after surgery. * be asked about their pain and how they're feeling at 4 timepoints during the 48 hours. * be asked about their pain 2 weeks after surgery. The participant and medical care providers will both be blinded to what IV treatment is being received. Researchers will compare the 2 groups to see if IV Lidocaine helps decrease the need of opioids, improves pain management, and reduces the risks of developing complications from prolonged opioid use (this includes opioid tolerance, opioid dependence, and opioid induced hyper-sensitivity to pain).

Comparison of the Efficacy of Celiac Plexus Blockade, ESP and Lidocaine Infusion Under OFA
Modern anesthesiology, in search of alternatives to opioid-based pain management, is turning to low-opioid and non-opioid protocols. Replacing opioids with non-opioid analgesics, co-analgesics, and regional and local anesthesia techniques allows avoiding the adverse effects of opioids while maintaining satisfactory analgesia. This is of particular importance in bariatric surgery, where reducing the incidence of respiratory depression, sedation, opioid hyperalgesia, and postoperative nausea and vomiting is a priority. Standard non-opioid anesthesia (OFA) includes ketamine, lidocaine, and dexmedetomidine infusions, while regional techniques additionally reduce the need for analgesics. Despite the widespread use of these methods, there is no clear data on the superiority of any of them in bariatric procedures.

Comparing Quality of Recovery Between ESPB and IV Lidocaine After Major Breast Cancer Surgery
The erector spinae plane block (ESPB) is gaining popularity as a regional anesthetic technique for major breast cancer surgery. Although there is controversy about its mechanism of action, emerging evidence suggests that clinical analgesia observed after ESPB in breast surgery may be due to rapid and sustained local anesthetic absorption from the injection site. Hence intravenous LA infusion (IVLI) during the perioperative period could offer an effective alternative to invasive ESPB.
Perioperative Pain Management for Lumbar Spine Surgery
Perioperative pain management is crucial for patients undergoing elective lumbar spine surgery. Moderate to severe postoperative pain can significantly impact recovery, worsen patient outcomes, and potentially lead to chronic pain. Opioids have traditionally been the mainstay of postoperative pain management. However, their use is associated with several adverse effects, including nausea, vomiting, respiratory depression, and the risk of developing chronic pain. To mitigate these risks, there is a growing emphasis on multimodal analgesic approaches that combine various non-opioid medications to provide effective pain relief. Non-opioid analgesics, such as nonsteroidal anti-inflammatory drugs (NSAIDs), regional anesthesia techniques, and adjuvant medications, can be used to reduce opioid requirements and improve patient outcomes. By carefully selecting and combining these modalities, clinicians can optimize pain management strategies for individual patients, minimizing the need for opioids and their associated side effects.
Effects of Different Doses of Intravenous Lidocaine Infusion on Peri-operative Pain and Incidence of Postoperative Chronic Pain Within ERAS Protocols, a Dose Finding Study.
This study aimed To investigate the effects of different doses of Intraoperative intravenous lidocaine infusion on intraoperative opioid consumption, perioperative pain control and incidence of postoperative chronic pain.
Postoperative Pain Control Following Hysteroscopy
Intraoperative lidocaine infusion is a frequently preferred method in surgical procedures due to its reducing the need for opioids, providing better postoperative pain control, reducing postoperative nausea and vomiting and increasing rapid recovery. Our aim in this study is to show the effect of intraoperative lidocaine infusion on reducing complications such as pain, nausea, vomiting, and the need for opioid analgesia that occur after hysteroscopy operations, which are often performed in gynecology clinics.
Continuous Lidocaine Infusion in Thyroid Surgery Using Intraoperative Neurophysiological Monitoring
Thyroid surgery is a common procedure for the treatment of thyroid tumors, nodules and other related lesions. During this procedure, intraoperative neurophysiological monitoring is used to protect the recurrent laryngeal nerves. For the nerve monitor to work properly, a reduced muscle relaxant dosage is indicated. The main objectives of the anesthesiologist are maintaining deep sedation, analgesia and immobilization during surgery, as well as enhance post-operative recovery. Reduced muscle relaxant use during surgery poses the risk of inadequate immobilization during the operation, which may result in serious surgical complications. Intravenous bolus administration of fentanyl is currently the most popular method to maintain the depth of anesthesia during such operations. However, the side effects include intraoperative hypotension, bradycardia, and postoperative nausea and vomiting. The ultra-short acting remifentanil may be appropriate for inhibiting the bucking reflex during surgery, but the risk of opioid-induced hyperalgesia and opioid tolerance after surgery has been reported. In recent studies, intravenous lidocaine has been shown to increase the depth of anesthesia and provide analgesia, with no muscle relaxing effect. The aim of this study is to examine the depth of anesthesia, surgical operating conditions, and the recovery profile with the use of a continuous lidocaine infusion.
Effect of Lidocaine Infusion on Neuraxial Opioid-induced Pruritus After Cesarean Section
The aim of this study is to assess the efficacy and potency of lidocaine infusion as a preventive measure on pruritus response after injection of 200 micro gram morphine with bupivacaine subarachnoid block, spinal anesthesia, in cesarean section.
Effect of Intraoperative Intravenous Lidocaine on Postoperative Pain and Return of Bowel Function After Cesarean Sections
Postoperative discomfort is a frequently seen adverse event after to caesarean operation. Early mobilization and bonding of the mother and her infant are typically impacted by this phenomenon. Nevertheless, the current state of postoperative analgesia and recovery remains inadequate in clinical settings. In the context of major abdominal surgery, opioids are often regarded as the preferred postoperative analgesic. Nevertheless, they possess adverse side effects that might impact the process of recuperation after surgery. These symptoms include nausea and vomiting, decreased bowel movement, and shallow breathing. One additional challenging consequence after surgery is the delayed restoration of bowel function, which has the potential to extend the duration of hospitalization and impede the initiation of oral feeding, resulting in gaseous colonic distension. The administration of lidocaine infusion has been shown to possess analgesic, anti-hyperalgesic, and anti-inflammatory characteristics. The use of intravenous lidocaine after surgery is postulated to have the dual effect of mitigating postoperative pain and expediting the resumption of bowel movements. Recent studies have shown that the administration of intravenous lidocaine, either as a single dosage or by continuous infusion, may have potential advantages in maintaining gastrointestinal motility and exerting an impact on biochemical pain mechanisms. However, the literature presents contradictory data about the effectiveness of lidocaine in providing sufficient postoperative pain relief and reducing postoperative ileus. Consequently, this study was conducted and aimed to assess the effect of intravenous intraoperative lidocaine on postoperative pain and early return of bowel function following elective caesarean section. This randomized clinical trial was conducted at Obstetrics and Gynecology Department, Faculty of Medicine, Cairo University Hospitals from August till December 2023. A total of 60 pregnant women underwent elective caesarean section were enrolled and randomized into two groups; experimental group who received IV infusion of lidocaine starting with skin incision, which was maintained until skin closure and control group who received 0.9% normal saline at the same rate as that described in the experimental group. Both groups were compared as regard total operative time, medications given, start-stop time of the study drug infusion, and degree of pain using visual analogue scale, need for analgesics, time for first healing of normal intestinal sounds and time to first flatus and symptoms of lidocaine toxicity were recorded.
Esmolol Versus Lidocaine on the Quality of Postoperative Recovery in Patients Undergoing Functional Endoscopic Sinus Surgery
Functional endoscopic sinus surgery (FESS) is one of the effective modalities for the treatment of chronic sinusitis, with the advantages of deep approach, light trauma, and less pain. However, because the operation area involves the nose, eyes and cranial region, the surrounding tissue structure is complex and rich in blood vessels and nerves, and the use of epinephrine, intraoperative tissue damage, nerve stimulation, and postoperative inflammation, edema, hemorrhage, and nasal cavity stuffing can cause patients' stress reaction and postoperative pain, resulting in patients' anxiety, depression, and sleep disorders, which can reduce the quality of early postoperative recovery, and affect the patients' rapid postoperative recovery. Esmolol is a selective β1-adrenergic receptor blocker with fast onset of action and short duration of action, which has the ability to reduce heart rate, blood pressure and myocardial protection. In recent years, several studies have found that esmolol not only reduces perianesthesia stress, but also reduces postoperative pain, decreases intraoperative and postoperative opioid requirements, and reduces the incidence of postoperative nausea and vomiting.In addition, intravenous lidocaine infusion has been shown to improve the quality of early postoperative recovery and accelerate postoperative recovery in patients with FESS.However, the dose of the drug administered is unclear and the range of safe infusion doses is narrow, requiring plasma concentration monitoring to prevent toxic reactions to local anesthetics. Its clinical application may lead to prolonged sinus bradycardia, increasing the cardiovascular risk of patients. Therefore, this study was designed to characterize the FESS procedure with the aim of determining that esmolol is not inferior to lidocaine in FESS in terms of the quality of postoperative recovery and is more advantageous in terms of controlling hemorrhage, guaranteeing a clear operative field, and the safety of the medication.
The Effect of Continuous Intravenous Infusion of Lidocaine on PPCs and Prognosis in Emergency Surgical Patients With IAI
The main purpose of this study is to evaluate the impact of continuous 24-hour intravenous infusion of lidocaine on the incidence of PPCs in patients undergoing emergency laparotomy for intra-abdominal infection (IAI).The secondary objectives of this study are to assess the impact of continuous 24-hour intravenous lidocaine infusion on the proportion of patients requiring mechanical ventilation, protection of important organ function during the perioperative period, length of hospital stay, and outcomes within 30 days postoperatively.

The investigators hypothesize that effect of addition of dexmedetomidine or ketamine by IV infusion to lidocaine infusion may be more beneficial than lidocaine infusion alone on proinflammatory cytokines (IL-1, IL-6 and TNFα), and postoperative pain relief and decreased opioid consumption, reduced Length of stay.
The Safety of Ropivacaine TAP Block Combined With Intravenous Lidocaine in Patients Undergoing Colorectal Cancer Surgery
Many studies have confirmed the analgesic effect of intravenous infusion of lidocaine in abdominal surgery. Transversus abdominis plane (TAP) block is also often recommended for abdominal surgery. Ropivacaine TAP block and intravenous lidocaine infusion are important components of multimodal analgesia for colorectal surgery. However, both of them are the local anesthetics and the safety of combination is unknown, so investigators design the study to explore the safety of the synergistic application of ropivacaine TAP block and intravenous lidocaine infusion in patients undergoing colorectal surgery.
Relationship Between Lidocaine and Serum Orphanin FQ (N/OFQ)
The intravenous injection of lidocaine during the perioperative period has been widely used in various types of surgeries. Its clinical effect includes reducing stress response during anesthesia, decreasing pain and opioid consumption, lowering the incidence of postoperative nausea, vomiting, cognitive dysfunction, and reducing the injection pain of propofol. However, despite the positive impact of lidocaine on surgical patients, its mechanism of action remains unclear. Serum N/OFQ is a neurotransmitter that plays an important role in regulating pain and emotion. Therefore, this study aims to explore the effects of perioperative intravenous injection of lidocaine on stress responses in surgical patients, as well as its mechanism of action, and whether Serum N/OFQ participates in this process.
Hemodynamic Responses of Dexmedetomidine, Lidocaine or Propofol Infusions During Laparoscopic Cholecystectomy

Continuous Lidocaine Infusion Via Closed Chest Drainage Tube for Pain Control After Thoracoscopic Partial Lung Resection
The goal of this clinical trial is to learn about the effects on postoperative analgesia of continuous lidocaine infusion via closed chest drainage tube for patients undergoing thoracoscopic partial lung resection. The main questions it aims to answer are: * To explore whether continuous lidocaine pumping via closed chest drainage tube has good analgesic and anti-inflammatory effects for patients undergoing partial thoracoscopic pneumonectomy. * Whether the multimodal analgesia combined with continuous lidocaine pump can reduce the postoperative application of opioids, reduce the occurrence of postoperative complications, and promote the recovery of postoperative lung function and accelerate recovery. For participants who undergoing the thoracoscopic partial lung resection with postoperative indwelling drainage tube, the epidural tube fixed in the drainage tube is connected to the completed infusion pump (marking the chest drain for analgesia). The comparison group only accept the intravenous analgesia after surgery.
Efficacy of Ultrasound Guided PIFB Versus Lidocaine Infusion on Postoperative Pain After Thoracotomy
Chronic pain is a common complication after cardiothoracic surgery. The prevalence of post-thoracotomy pain syndrome (PTPS) ranges from 33% to 91%. Exact pathogenetic mechanisms for developing chronic pain after thoracotomy are unknown. Apart from intraoperative nerve damage and subsequent postoperative neuropathic pain, operation techniques, age, sex, pre-existing pain, genetic and psychosocial factors, severe postoperative pain, and analgesic management are suspected to have an impact on the development of PTPS .

Dose Systemic Lidocaine Improve the Quality of Recovery After Colorectal Endoscopic Submucosal Dissection
Endoscopic submucosal dissection (ESD) is a common procedure that requires a long procedural time. Procedure Sedation is commonly provided to alleviate patients' discomfort and facilitate the implementation of procedures. We conducted a prospective study to determine the effect of intravenous infusion of lidocaine in the cognitive domain of the postoperative quality of recovery scale on day 3 after ESD.
Lidocaine Improves Satisfaction in Labiaplasty
1.Written informed consent must be obtained before any study specific procedures are undertaken.Qualified participants were identified at the pre-anesthesia evaluation clinic or ward. 2.80 patients with American Society of Anesthesiologists (ASA) score of I-II in our medical center scheduled to undergo elective surgery for hypertrophy of labia minor with MAC. Patients were randomized 1:1 into the Group 1 (normal saline) or Group 2 (lidocaine 1.5 mg/kg/hr, ideal body weight) by using a table of random, computer-generated digits in sealed and numbered envelopes by an anesthesiologist. All surgical procedure was performed by the same surgeon and the anesthetic data was recorded by a nurse anesthetist. All patients were fasted overnight before the procedure, and no medications were allowed before induction of anesthesia. Standard monitoring, such as non-invasive arterial blood pressure, electrocardiography (lead II), pulse oximetry, end-tidal carbon dioxide pressure (EtCO2) was applied for each patient. Participants were pre-oxygenated and adequately maintained with 100% oxygen at 3 L/min via a nasal cannula during the entire procedure. During anesthesia induction, all patients received intravenous fentanyl 0.5-1 mcg/kg, continuous infusion of propofol with target-controlled infusion (TCI; Fresenius Orchestra Primea; Fresenius Kabi AG, Bad Homburg, Germany) with the Ce of 4.0 mcg/mL and parecoxib. In addition, continuous infusion of equal volume normal saline and lidocaine 1.5 mg/kg/hr (ideal body weight) in group I and 2, respectively. In all patients, maintenance of the Ce of propofol was adjusted upward or downward by 0.5 mcg/mL to keep patient adequate sedation with acceptable pain (remaining moveless). If upward 2 times of propofol and the patient still move which affect the surgical procedure, fentanyl 0.5 mcg/kg was prescribed, and mean arterial pressure (MAP) and heart rate (HR) within baseline levels. As soon as the last suture, the propofol and lidocaine were discontinued. After the procedure, all patients were sent to the PACU for further care under clear consciousness.

Intraoperative Lidocaine Infusion and Surgery-induced Release of Pro-inflammatory Cytokines After Abdominal Surgery
Lidocaine is an amide local anaesthetic and an antiarrhythmic agent, first synthesized in 1942, and after approval for human use was launched in 1948 in Sweden The first observations of post operative analgesic effects of perioperative intravenous lidocaine (IVL) were initially proposed in 1951 subsequently many more enthusiastic reports followed. Postoperative formal clinical evaluations in the perioperative setting were conducted in the late 1950s where IV Lidocaine was demonstrated to have a postoperative analgesic effect without posing the risk of respiratory depression, reducing the occurrence of postoperative nausea and vomiting (PONV), and enhance post-surgical recovery. IV Lidocaine also potentiated the depth of anesthesia and led to a better tolerance of endotracheal intubation.Around 40% of patients experience a delay in resumption of normal bowel function after colorectal surgery. This delay leads to symptoms of nausea, vomiting, constipation, and abdominal distension, which then require unpleasant supportive interventions such as intravenous fluids and nasogastric tube insertion. There is no remedy to address this delay. ALLEGRO, "A placebo-controlled randomized trial of intravenous Lidocainein accelerating Gastrointestinal Recovery surgery," is the latest ongoing multicenter research study across the United Kingdom, investigating the use of intravenous lidocaine to improve recovery after colorectal surgery

Lidocaine Infusion With ERAS Protocol for Pancreatic Cancer Surgery: Effect on Pain and Patient Immunity.
The whole world now is directed to implement strategies that enhance the patient's quality of life and prevent tumor relapse. Enhanced recovery after pancreatic surgery (ERAPS) program was found to improve the quality of life as it is an evidence-based protocol designed to standardize and optimize perioperative medical care in order to reduce surgical trauma, perioperative physiological stress, organ dysfunction, reduction of clinical complications, length of hospital stay and the health costs together with increase of patient satisfaction. lidocaine; it is an amide local anaesthetic Recently its use as intravenous perioperative infusion for abdominal cancer surgeries is encouraging, as it significantly reduces postoperative pain, opioid consumption and nausea and vomiting. it also promotes gastrointestinal function recovery, and shortens the postoperative hospital stay. In addition, lidocaine in particular can act directly and indirectly on pancreatic cancer cells and the tumor microenvironment. The investigators suggest that IV lidocaine infusion in combination with ERAPS protocol may achieve better postoperative outcomes after pancreatic surgery for cancer.
Lidocaine VS Hemodynamic, Metabolic and Hormonal Response

A Clinical Trial of Intravenous Lidocaine After Spinal Surgery to Prevent Delirium and Reduce Pain
Postoperative delirium is one of the most frequent adverse events following elective non-cardiac surgery and is associated with cognitive impairment at discharge, as well as in-hospital and long-term mortality, however, despite being a well-recognized problem there is a dearth of effective interventions for prevention and management. A modifiable risk factor associated with postoperative delirium is poor postoperative pain control, and by improving the pain regimen the investigators may be able to decrease the incidence and/or severity of postoperative delirium. In this study, the investigators seek to study whether a postoperative intravenous infusion of lidocaine, known to improve pain control in other contexts, can decrease the risk of postoperative delirium and other opioid-related side effects, following major reconstructive spinal surgery.
Low-Dose Lidocaine Infusion for Acute Pain Management Pilot Study
The purpose of this study is to evaluate the safety and efficacy of lidocaine infusion in acute pain management following open abdominal surgery, including opiate use after surgery and the incidence of postoperative nausea and vomiting, Ileus, length of stays (ICU/hospital), and improvement in patient satisfaction.
Evaluation of Intravenous Lidocaine and Time to Regression of the Sensory Block After Spinal Anesthesia (ELSA Trial)
The use of intravenous lidocaine in continuous infusion in the perioperative period is associated with a reduction in postoperative pain scores, opioid use, incidence of nausea and vomiting, among other favorable outcomes. However, this therapeutic intervention has not yet been adequately evaluated by clinical trials when associated with regional anesthesia. The aim of this study is to evaluate whether the use of intravenous lidocaine in continuous infusion during spinal anesthesia with isobaric bupivacaine alters the time to regression of sensory block in patients undergoing surgical procedures for the treatment of bone and connective tissue tumor surgeries. This will be a triple-blind randomized trial. The sample size estimated was 66 patients. The study will include all patients who meet the pre-established inclusion and exclusion criteria, choose to participate, and agree with the Informed Consent Form. The main anesthetic technique will be spinal anesthesia with 13 mg of isobaric bupivacaine. Patients will be allocated in two groups in a blindly after randomization: Group S (lidocaine 0.75mg.kg-1 in bolus followed by infusion of saline solution) and Group L (lidocaine 1.5 mg.kg-1 followed by continuous infusion of lidocaine solution at 2 mg.kg-1.h-1). The primary outcome will be the time to T12 regression of the sensory block. Will also be evaluated: time to regression of the motor block, most rostral dermatome achieved by the sensory block, time to two-segment regression oh the sensory block, propofol dose in the operating room, postoperative pain score at rest, pain at movement score, quality of recovery, use of opioids in the postoperative period, nausea or vomiting, dizziness, shivering, arrhythmias, hypotension, urinary retention, and length of stay. The records will be assigned to the RedCap database. The data will be extracted without identification of the allocation groups for the R software and the groups will be revealed to the researcher after the end of the statistical analysis to write the summary of the results. The results will be submitted to scientific journals afterward.

In the lidocaine groups, at the beginning of surgery, lidocaine 0.5mg/kg, 1.0mg/kg, and 1.5mg/kg per hour were continuously infused (using ideal body weight) respectively during the whole procedure. In contrast, the control group was infused with the same dose of normal saline. All the infusion procedures will be stopped at the end of surgery
Continuous Nerve Block Block vs Combination of Single Block Plus Intravenous Lidocaine for Postoperative Pain.
A multimodal analgesic regimen including regional anesthesia is used at UPMC Shadyside for primary thoracic and major abdominal surgeries. The current standard-of-care regional anesthesia techniques include Erector Spinae Plane (ESP) block for video assisted thorascopic surgery (VATS) and Quadratus Lumborum (QL) block for major abdominal surgery. These blocks are routinely administered as a continuous catheter technique in order to extend the duration of postoperative analgesia. Although rare, continuous nerve block techniques carry risks and limitations, including catheter dislodgement, migration, kinking and leaking at the site, bleeding, and infection. They are also much more expensive to perform and maintain than single-injection nerve blocks at this institution. Perioperative intravenous (IV) lidocaine is one of the safest local anesthetics, and its use has been shown to provide analgesia and reduce opioid requirements. Furthermore, it has been hypothesized that part of the analgesic efficacy of continuous peripheral nerve blocks may be due to the systemic effects of the local anesthetic infused at the site. Therefore, it is possible that the combination of a single block followed by an infusion of IV lidocaine may provide the same benefits as a continuous nerve block at a lower cost. The purpose of this study is to show that a single block technique plus IV lidocaine is non-inferior to a continuous block technique. For the purpose of this study we chose two surgical models--VATS and major abdominal surgery--and ESP and QL blocks, respectively. The study will be conducted as a prospective, randomized (1:1), open-label, active-comparator, noninferiority trial. The study will prospectively investigate the efficacy of continuous block versus single block plus IV lidocaine infusion for postoperative pain management in patients undergoing primary unilateral VATS or primary major abdominal surgery.

Opioid-sparing technique with multimodal analgesia is recommended but the evidence supported is still limited. Multimodal analgesia, particularly lidocaine and ketamine, has been used effectively in various type of surgery. However, the evidence supported their use in obese patients undergoing bariatric surgery is limited.
Effect of Co-administration Lidocaine and Dexmedetomidine on Quality of Recovery
BACKGROUND: Some studies have revealed that intravenous (IV) lidocaine or dexmedetomidine might improve the quality of recovery undergoing laparoscopic surgery. The investigators investigated whether co-administration lidocaine and dexmedetomidine could better improve the the quality of recovery after laparoscopic total hysterectomy. METHODS: One hundred and forty-four women with elective laparoscopic total hysterectomy were randomly divided into four groups: Patients in group L received a bolus infusion of lidocaine (2%; 1.5 mg/kg over 10 min before the induction of anesthesia), and then lidocaine was infused at a rate of 1.5 mg/kg/h until close the pneumoperitoneum. Patients in group D received a bolus infusion of dexmedetomidine (0.5 µg/kg over 10 min before the induction of anesthesia), and then dexmedetomidine was infused at a rate of 0.4 μg/kg/h until close the pneumoperitoneum. Patients in group LD received a bolus infusion of lidocaine (2%; 1.5 mg/kg) and dexmedetomidine (0.5 µg/kg) over 10 min before the induction of anesthesia, and then lidocaine and dexmedetomidine were infused at a rate of 1.5 mg/kg/h and 0.4 µg/kg/h until close the pneumoperitoneum, respectively. Patients in group C received the same volume of normal saline 10 min before the induction of anesthesia, and then normal saline (0.9%) was continuously infused in an equal volume until close the pneumoperitoneum. Primary outcome was the quality of recovery (QoR-40) at 1 day prior to sugery, 1 day after sugery, and 2 days after sugery. The secondary outcomes included perioperative remifentanil consumption, postoperative VAS scores, the incidence of postoperative nausea and vomiting, postoperative rescue analgesics and anti-emetics, recovery time, extubation time, and Ramsay sedation scale at 5 min, 10min, 30 min, 60 min after extubation.
Opioid Sparing Anaesthesia for Prevention of Postoperative Nausea and Vomiting in Laparoscopic Gynecological Surgery
In spite of multimodal analgesic strategies, which consist of opioids, dexamethasone, non-steroidal anti-inflammatory drugs, and local anesthetics applied into the surgical wound, postoperative pain and postoperative nausea and vomiting (PONV) are still common complaints reported after laparoscopic gynecological surgery. So, it is hypothesized that the infusion consisting of lidocaine, dexmedetomidine and ketamine, as an opioid substitute was a feasible technique for laparoscopic gynecological surgery and would be associated with less incidence of PONV and lower opioid requirements in the early postoperative period. The aim of this study was to evaluate the effect of opioid sparing technique via infusion of Dexmedetomidine, Ketamine and Lidocaine on post-operative nausea and vomiting in laparoscopic gynecological surgery.
Lidocaine Versus Duloxetine for the Prevention of Taxane-Induced Peripheral Neuropathy In Breast Cancer Patients

The current study is a single blinded randomized controlled study, assumed that lidocaine could prevent and reduce TIPN similar to duloxetine in patient with breast cancer. Method of randomization: The allocation sequence was generated using permuted block randomization technique and the block size was variable. Allocation sequence/code was concealed from the person allocating the participants to the intervention arms using sealed opaque envelopes. Primary outcome: Degree of neuropathic pain measured by neuropathy pain scale (NPS) among breast cancer patients on Taxane chemotherapy after the pretreatment with either lidocaine or duloxetine. Secondary outcomes are: The incidence of TIPN using DN4 questionnaire and nerve conduction study and Patients' quality of life using The European Organization for Research and Treatment of Cancer (EORTC) QLQ-CIPN20 as well as the Change in serum level natural killer cell to estimate cell mediated immunity.
Intravenous Lidocaine for Pain Associated With Pancreatic Cancer and Chronic Pancreatitis
Pain is a major clinical problem for many patients with pancreatic cancer and chronic pancreatitis (CP).In pancreatic cancer, nearly 75% of patients suffer from pain at the time of diagnosis, with over 90% of patients in advanced stages. In CP, pain occurs in 80-90% of patients and strongly affects quality of life. For both conditions, the majority of pain is addressed using the WHO analgesic ladder. However, more invasive pain therapies are often necessary. Currently, in several centers in the Netherlands, treatment with IV lidocaine is already used in clinical practice in patients with pancreatic cancer and CP. Based on practical experience, the majority of patients benefit from this therapy, however, its efficacy in terms of duration of pain relief, decrease in pain scores, increase in patient satisfaction and adverse events is unknown. Therefore, the aim of this study is to investigate the efficacy of monitored single intravenous infusion in patients with pancreatic cancer and CP.

Half of the patients will receive intravenous lidocaine and the other half will receive intravenous NaCl 0,9 % as placebo.
PVB vs Ketamine/Lidocaine in Rib Fracture Patients
Rib fractures are a common admission to the trauma service. The mainstay of treatment is pain control to improve respiratory effort in order to offset the risk of pneumonia and mechanical ventilation. In addition to standard pain control modalities, the investigator's institution utilizes paravertebral blocks as well as lidocaine and ketamine infusions for pain control. The current standard of care for pain control is to begin with acetaminophen, ibuprofen or celecoxib and opioids with the addition of paravertebral blocks as needed. In certain situations, a paravertebral block is contraindicated, and pain control is relegated to lidocaine and ketamine infusion. The use of lidocaine infusion alone and ketamine infusion alone for pain control has been studied and has been shown to be safe. However, concurrent use of these two medications to control rib fracture pain is relatively new and the efficacy compared to paravertebral block is not known. The goal of the study is to show non-inferiority of simultaneous lidocaine and ketamine infusions versus paravertebral blocks.

Effects of Lidocaine Infusion on Quality of Recovery and Agitation After Functional Endoscopic Sinus Surgery
The essential anesthesia requirements for FESS include airway management, considerations for facilitating surgical access, provision of a clear and still surgical field for precision surgery, assuring quick and non-stimulating emergence from anesthesia, and fast-tracking patients for discharge. Postoperative agitation, although short-lived, is potentially harmful to both patients and recovery room staff, it has a potential for self-injury by removing intravenous catheters, tubing, oxygen masks and nasal packs. Furthermore, very agitated patients can pose an immediate danger to operating theatre staff.
Therapeutic Efficacy of Intravenous Lidocaine Infusion Compared With Epidural Analgesia for Postoperative Pain Control in Adult Patients Undergoing Major Abdominal Surgery: Non-Inferiority Clinical Trial
Major abdominal surgery continues is one of the most performed surgical procedures in the world, both electively and urgently. One of the main problems of this type of intervention is postoperative pain. it is shown that it increases health costs related to longer recovery times, longer hospital stay and related complications such as the increased risk of presenting chronic POP pain, which it has been estimated up to 20%, much higher if the surgery involves surgery in the gastrointestinal system. The goal of analgesia in the postoperative setting is precisely to provide comfort to patients, minimize adverse effects and complications arising from the procedure. The epidural analgesic technique (has been proposed as an analgesic management standard, since multiple studies have shown that it reduces opioid consumption, improves recovery and is a useful strategy for pain control. However, it is an invasive technique, with risk of complications such as hematomas and epidural abscesses, and it may be difficult to perform. Currently it has been shown in multiple studies that the intravenous infusion of a local anesthetic, such as lidocaine, in this type of surgical scenarios can reduce the intensity of pain, opioid consumption, hospital stay and ileus with few adverse effects. In addition, these studies propose that, being a less invasive technique, it could be easier to implement and even be safer than the epidural technique. The main hypothesis of this study is precisely that the infusion of lidocaine may be non-inferior to epidural analgesia in the analgesic management of patients undergoing major abdominal surgery.
Continuous Intravenous Lidocaine Infusion Versus Placebo for Rib Fracture Analgesia
The current cornerstone of pain control for rib fractures is oral and intravenous opioids, especially in the form of patient-controlled analgesia (IV PCA), which are are associated with multiple adverse effects including sedation, respiratory depression, cough suppression, and increased risk of delirium. In the past few decades, intravenous lidocaine infusion (IVL) has emerged as a new tool in the arsenal of multimodal analgesia. Multiple randomized clinical trials have indicated that IVL is overall well tolerated and have shown other beneficial effects such as anti-inflammatory properties. To this date, there have been no published randomized clinical trials (RCT) evaluating the effectiveness of IVL in management of traumatic rib fracture pain. Therefore, the purpose of this study is to evaluate whether IV Lidocaine infusion can provide improved pain control as demonstrated by decreased OME consumption at 24 and 48 hours compared to placebo in adult patients with acute traumatic rib fractures.
Systemic Lidocaine Infusion for Pain Control in Ventral Hernia
Ventral hernia repair leads to more than expected pain. This is thought to be secondary to nerve pain at the lateral transfixion sutures. Systemic lidocaine given pre-op has in other situations decreased neurogenic pain. This study will examine its effects on pain experienced after ventral hernia repair.
Intravenous Lidocaine in Open Lung Resection Surgery
Management of postoperative pain in 2020 remains a challenge for anesthesiologists in the perioperative period. Lidocaine is an amide local anesthetic, it is one of the oldest adjuvant analgesics and is known to possess analgesic, anti-hyperalgesic and anti-inflammatory properties. Lidocaine is proven to be as effective as epidural analgesia in colorectal surgery. However, no study has evaluated the effect of a continuous lidocaine infusion for open lung resection in the post-operative period. The present study aims to evaluate the influence of IV lidocaine given during and 24 hours after surgery, on pain scores, opioid consumption, and possible benefits on patient outcome via the opioid-sparing effect in open thoracic surgery
Effect of Opioid Free Anesthetic on Post-Operative Opioid Consumption After Laparoscopic Bariatric Surgery
A comparison of post-operative opioid use in laparoscopic bariatric surgery patients receiving opioid or opioid-free anesthesia.
IV Lidocaine Analgesia in Pediatric Scoliosis Surgery
Surgical correction of scoliosis in children is a long procedure, with an equivalently long recovery time, that is commonly performed at BC Children's Hospital. Treating pain immediately after the procedure is a priority for children during recovery. Morphine is one medication that can be used to manage post-operative pain, but unfortunately, its use is accompanied by a number of side effects which can affect recovery. These include nausea, vomiting, pruritus, sedation, dysphoria, respiratory depression, constipation, ileus, and urinary retention. In order to control pain and reduce morphine consumption, intravenous lidocaine is being investigated. This therapy has been beneficial in adult populations undergoing abdominal surgery and has been associated with decreased post-operative pain, decrease use of opioids including morphine, and ileus. These all contribute to shorter lengths of stay in the hospital and better recovery in the adult population. Intravenous lidocaine is used by some anesthesiologists at BC Children's Hospital to manage post-operative pain in children receiving surgical correction for scoliosis, but this is not a standard of practice. We now propose to conduct a double-blind randomized controlled trial to determine if intravenous lidocaine, infused from start of anesthesia up to 48 hours post-operatively, will reduce morphine use and improve post-operative pain in the pediatric population.
Perioperative Lidocaine and Ketamine in Abdominal Surgery
The investigators propose to test the hypothesis that perioperative infusions of lidocaine and/or ketamine reduce opioid consumption and pain scores in adults recovering from elective inpatient abdominal surgery.
Intrauterine Anesthesia in Operative, Awake, Office Hysteroscopy. A Randomized Double-blind Placebo-controlled Trial
Objective: to evaluate intrauterine lidocaine infusion effectiveness in reducing pain associated with operative, awake office hysteroscopy Methods: A total of 100 patients will be randomized for this study The control group underwent hysteroscopy using a saline distension medium. The study group underwent hysteroscopy using 10ml of 2% lidocaine that was added to the first liter of distension medium. Patients quantified their pain using a 0-10 VAS score, at the following five predefined points: baseline, before the procedure; while inserting the hysteroscope through the cervix; during the operative procedure; immediately after the procedure and 15 minutes following the procedure.
The Study of Perioperative Intravenous Infusion of Lidocaine on Postoperative Analgesia in Patients Undergoing Single-port Thoracoscopic
The purpose of this study is to evaluate the effect of intravenous lidocaine infusion on pain and opioid dosage in patients undergoing single-port thoracoscopic surgery,and to evaluate the effects of perioperative catecholamine levels, extubation time, incidence of nausea and vomiting, patient satisfaction and hospital stay.
RIB PAIN (Rib Fractures Treated With Parental Analgesia With Infused LidocaiNe)
Traumatic rib fractures (RF) are a relatively common occurrence in patients of all ages, with a 10% incidence in all trauma patients and are associated with significant morbidity and mortality. Adequate analgesia is paramount for preventing pulmonary complications and can reduce morbidity and mortality. There is longstanding evidence of lidocaine's effectiveness and safety in the post-operative patient and the investigators hypothesize that this modality may prove to be ideal in trauma patients with RF. Therefore, it is imperative that intravenous lidocaine be investigated to ascertain if there is significant benefit for pain reduction in patients who have sustained rib fractures. A single-centre, double-blind, randomized control trial to evaluate the analgesic efficacy of a 72-96 hour IV lidocaine infusion plus standard analgesics versus placebo infusion plus standard analgesics will be performed on patients (age 18 or older) diagnosed with two or more traumatic rib fractures ,from blunt thoracic trauma, requiring hospital admission at Victoria Hospital. The primary outcome is mean pain score, as measured on the Visual Analog Scale (VAS) when the patient is at rest and with movement. Secondary outcomes are protocol adherence, patient satisfaction as measured on the VAS, incidence of respiratory failure requiring mechanical ventilation, hospital length of stay, ICU length of stay, mortality, incidence of lidocaine toxicity, treatment regimens (use of additional non-opioid analgesics) and total morphine equivalents used (including breakthrough doses). This trial will serve to quantify the analgesic efficacy of intravenous lidocaine for patients with traumatic rib fractures. Successful completion of a single centre trial will inform the development of a multi-centre trial powered to demonstrate a reduction in respiratory failure in the trauma population.
Dexmedetomidine Combined With Lidocaine Infusion Affect PONV
BACKGROUND: Few researches have manifested that intravenous (IV) lidocaine or dexmedetomidine decreased the incidence of postoperative nausea and vomiting (PONV). The investigators investigated whether IV lidocaine plus dexmedetomidine infusion could better reduce the incidence of PONV after laparoscopic hysterectomy. METHODS: Two hundred and forty women with elective laparoscopic hysterectomy were randomly divided into four groups: the control group (group C, n=60) received an equal volume of saline, the lidocaine group (group L, n=60) received IV lidocaine (bolus infusion of 1.5 mg/kg over 10 min, 1.5 mg/kg/h continuous infusion), the dexmedetomidine group (group D, n=60) received dexmedetomidine administration (bolus infusion of 0.5 µg/kg over 10 min, 0.4 µg/kg/h continuous infusion), the lidocaine plus dexmedetomidine group (group LD, n=60) received combination of lidocaine (bolus infusion of 1.5 mg/kg over 10 min, 1.5 mg/kg/h continuous infusion) and dexmedetomidine administration (bolus infusion of 0.5 µg/kg over 10 min, 0.4 µg/kg/h continuous infusion). Primary outcome was the incidence of the first 48 h nausea, vomiting and PONV after surgery. The secondary outcomes included perioperative propofol and remifentanil consumption, postoperative fentanyl requirement, Ramsay sedation score, and bradycardia during post-anaesthesia care unit (PACU) stay.
Effect of Introperative Ketamine and Lidocaine Infusion on Postoperative Opioid Consumption in Posterior Spinal Fusion Surgery
Objective: The primary aim of this study was to investigate the effect of ketamine and lidocaine on postoperative opioid consumption in posterior spinal fusion surgery. Materials and Methods: Ethics committee approval was received from our faculty. Seventy-five cases between the ages of 18-65, who have an ASA (American Society of Anesthesiologists) risk classification I-II-III in the preanesthetic evaluation, planned to be operated by the Neurosurgery clinic for lumbar posterior spinal fusion surgery under elective conditions have been included in the study after the informed volunteer consent form was read and approved. The patients were randomly divided into 3 groups using the closed envelope method. The ketamine group (Group K) (n = 25), the lidocaine group (Group L) (n = 25) and the placebo group (Group P) (n = 25). Propofol, rocuronium and fentanyl i.v. done. In group K, 0.5 mg / kg i.v. ketamine bolus and 0.25 mg / kg / hr i.v. ketamine infusion was administered. In group L, 1.5 mg / kg i.v. lidocaine bolus and 1.5 mg / kg / hr i.v. lidocaine infusion was administered. In group P, i.v. saline (in the same volume and duration) was applied. Maintenance of anesthesia was provided by propofol and remifentanil infusion. The propofol and remifentanil doses were adjusted according to the BIS monitoring and the increase or decrease in basal blood pressure and heart rate values of 20% or more. The BIS value was kept between 40-60. At the end of surgery, infusions were closed. After extubation, the patients were taken to the recovery room. Patient controlled analgesia (PCA) prepared with fentanyl was applied to the patients for postoperative analgesia. The PCA device was attached for 24 hours postoperatively. Postoperative 0-4 hours, 4-8 hours, 8-24 hours and total fentanyl consumption of the patients were evaluated. Pain scores were measured at 1, 2, 4, 8, 12 and 24 hours in the postoperative recovery room. Intraoperative propofol and remifentanil consumption was recorded. Tramadol 1 mg / kg i.v. as rescue analgesia (in patients with VAS pain score of 4 and above) done. Possible side effects due to opioid, ketamine and lidocaine were followed.
Lidocaine Infusion for Pain Relief in Children Scheduled for Tonsillectomy and Adenoidectomy
Lidocaine is widely available and is a very commonly used local anesthetic. When administered intravenously, lidocaine infusions have anti-inflammatory effects and have significantly decreased the reliance on opioid use for adequate pain management in adult abdominal and spine surgeries. A major advantage of lidocaine infusion is that it is not associated with a significant side effect profile.The role of lidocaine in pediatric acute perioperative pain remains limited.
Intravenous Lidocaine in Children Undergoing Laparoscopic Appendectomy
Intravenous lidocaine - a potent local anesthetic with analgesic and anti-inflammatory properties has been shown to be an effective adjunct that reduces intra and postoperative opioid consumption and facilitates pain management in adults. In children population promising but limited evidence is available. The study was planned to evaluate the efficacy of continuous intravenous infusion of lidocaine to reduce opioid consumption during and after laparoscopic appendectomy in children.
Effect of Perioperative Intravenous Lidocaine Infusion in Robotic-Assisted Urologic Surgery
Controlling pain is fundamental during and after surgical procedures. This study examines pain associated with robotic assisted surgery on prostate cancer or a kidney mass. In recent years, the risk of opioids in the postoperative period has gained interest due to the growing epidemic of addiction, dependence, and overdose. In this study, the investigators expect a continuous infusion of intravenous lidocaine during the perioperative period to result in less pain and less opioid use.
Impact of Intra- and Postoperative Continuous Infusion of Lidocaine on Analgesia in Vascular Anaesthesia
The aim of the study is to test the effectiveness and safety of the use of lidocaine infusion in multimodal analgesic management. A group of patients undergoing vascular surgery performed with the classic technique on the aorta - with the opening of the abdominal cavity will be enrolled. The population of patients qualified for this type of vascular surgery is usually burdened with multiple diseases, mainly risk factors or cardiovascular diseases, which, combined with hemodynamic fluctuations, large fluid shifts (including bleeding) and stress for the body, affects the risk of serious cardiological complications, which in this group exceeds 5% and is the highest, according to the ESC / ESA (European Society of Cardiology / European Society of Anesthesiology) classification from 2014. Proper postoperative pain control is therefore becoming one of the key pillars of postoperative care in this group of patients. Due to the numerous disease burden of patients and the operational specifics, the use of multimodal therapy in the management of pain is of particular importance, as the use of high doses of opioids improves hemodynamic stability, but at the same time affects the occurrence of side effects - mainly excessive sedation, respiratory disorders, hypoventilation and, consequently, for hypoxia of the heart muscle. The risk of myocardial injury in non-cardiac surgery (MINS) is significant in the light of the available literature. Lidocaine used in intravenous infusion is one of the recommended components of multidirectional analgesia. Its adjuvant properties make it possible to reduce the amount of opioid drugs used, and thus - to reduce the frequency of their side effects. The high effectiveness of such a procedure has been proven in numerous experimental and epidemiological studies. Due to the low frequency of side effects associated with its use, the therapy has a strong recommendation for use in relieving perioperative pain. The analysis of the literature on the subject shows that there is little data assessing effectiveness of lidocaine infusion in relation to the group of patients after surgery on the abdominal aorta.
Lidocaine Infusion in Pancreatic Cancer

Lidocaine Infusions for Rib Fractures
Patients with traumatic rib fractures not receiving regional anesthesia through a epidural or nerve block catheter will be recruited for the study. Once enrolled, they will be randomized to receive either intravenous lidocaine or intravenous saline for control of pain related to their rib fractures. In addition, they will receive other pain medications, such as acetaminophen, gabapentin, and opioid pain medications. Our primary outcome is a decrease in their opioid medication requirements.
The Effect of Perioperative Intravenous Lidocaine Infusion on Opioid Consumption After Lumbar Spine Surgery
The purpose of this study is to determine whether an infusion of lidocaine during surgery can reduce the need for postoperative opioid pain medication use in patients undergoing lumbar spine surgery. Participants will be recruited by spine surgeons from their pool of patients who are presenting for surgery at University of Vermont Medical Center. If they agree to participate, patients will be assigned at random to receive either an infusion of lidocaine during surgery, or an infusion of saline with 5% dextrose. Subjects will also be asked to complete a 15-item questionnaire that asks about health, quality of life, and level of pain, at three timepoints. Patients will also be asked to rate their level of pain at multiple timepoints after surgery, and we will collect the additionally data from patients' medical records.
Multimodal Analgesia Versus Traditional Opiate Based Analgesia
Pain after cardiac surgery can be moderate to severe with incisions to the sternum and lower extremities, and also the placement of chest tubes. Postoperative pain may contribute to delirium, stress, myocardial oxygen demand supply imbalance, etc. Traditionally postoperative pain management after cardiac surgery has been based on opiate analgesics. However, opiates have many deleterious side effects including nausea/vomiting, ileus, bladder dysfunction, and respiratory depression, which substantially influence patient recovery and may delay discharge after surgery. The current study is designed to evaluate if an opiate sparing multimodal regimen of tylenol, gabapentin, ketamine, lidocaine and dexmedetomidine provided better analgesic effect (pain score, postoperative PCA opioid dose), less side effects (PONV) and improved cardiac surgery outcome (delirium, a-fib, AKI, dysglycemia) compared to a traditional fentanyl and hydromorphine regimen after cardiac surgery. Additionally, it aims to investigate if the benefit of multimodal regimen is achieved by combination of all drugs or all drugs except dexmedetomodine by introducing third group of study patients who will be randomized to all interventions except saline placebo instead of dexmedetomodine infusion.
Usefulness of Lidocaine in Oral and Maxillofacial Surgeries Under General Anesthesia for Pain Control After Operation

Lidocaine group will receive intravenous bolus 1.5 mg/kg at induction followed by continuous infusion of 2 mg/kg/hr until the completion of surgery.Normal saline group will receive same amount of intravenous normal saline .The primary outcome will be postoperative pain using the NRS scale during first 24 hours and time to first analgesic request
Effect of Perioperative Intravenous Lidocaine Infusion on Postoperative Recovery in Patients Undergoing Arthroscopic Rotator Cuff Repair Under General Anesthesia
Arthroscopic rotator cuff repair is a commonly performed procedure but is known to cause significant postoperative pain. Effective analgesia after rotator cuff repair is crucial in improving the well-being of the patient but also to ensure long-term rehabilitation. The most commonly used analgesic for acute postoperative pain is opioids. However, the use of opioids is accompanied by several side effects which include but are not limited to nausea/vomiting, urinary retention, itching sensation and sometimes dizziness, respiratory depression and hypotension in higher doses. As of late, many efforts are aimed toward decreasing the use of opioids by using multimodal analgesia. Among such methods, intravenous lidocaine has been reported to be effective, safe and economic in various procedures. However, the existing evidence is mostly focused on laparoscopic procedures. The present study aims to find whether perioperative infusion of lidocaine is able to decrease opioid requirements after surgery and also improve postoperative pain compared to placebo in patients undergoing arthroscopic rotator cuff repair.
Ambulatory Infusions of Lidocaine and Ketamine for Management of Chronic Pain
As lidocaine and ketamine provide analgesia by acting on different molecular pathways, administering them together may produce synergistic effects, which can allow for using a lower dose of each medication and thereby reducing the corresponding side effects. To the investigator's knowledge, despite the common practice of multimodal analgesia, lidocaine-ketamine infusions have never been studied prospectively in an out of hospital setting to treat neuropathic pain. The aim of the present study is to evaluate the effectiveness of the current routine practice of lidocaine-ketamine infusions conducted at Allevio Pain Management Clinic, a large outpatient community based chronic pain management facility. Lidocaine-ketamine infusions are prescribed to patients that have pain that is considered to be neuropathic for which standard anti-neuropathic medications have been ineffective or poorly tolerated by patients. A prospective longitudinal study.

Adverse events will be recorded.
Anesthesia and Postoperative Outcome in Colorectal Cancer Patients
Study aims to compare the influence of TIVA and sevoflurane anesthesia with or without lidocaine on postoperative short and long term outcome in patients with colorectal cancer undergoing surgery. As short term endpoints postoperative pain and opioid consumption, resumption of bowel function, PONV, LOS will be registered. Long term outcome parameters include: the incidence of chronic pain, 1 and 5 years cancer recurrences incidence and mortality.
IV Lidocaine Infusion for Neuropathic Pain
The investigators will conduct a retrospective cohort study of patients who have undergone i.v. lidocaine infusions in the previous 2 years for suspected neuropathic pain of heterogeneous origin. The investigators hypothesize that the analgesic response to intravenous (i.v.) lidocaine will be bimodal with clear responders and clear non-responders. The investigators also hypothesize that more refractory patients, who have failed previous multimodal analgesic therapy, will be less likely to respond to i.v. lidocaine. The investigators goals are to report what percentage of patients will achieve relief, the degree of relief that can be expected, and identify the type of patients who will most likely to benefit from systemic lidocaine. The investigators secondary objective is to report the correlation between infusion rates and patterns of infusion rate adjustments with regard to efficacy and adverse effects.

Efficacy and Safety of Lidocaine Infusion Treatment in Management of Neuropathic Pain
The investigators conducted a randomized, Double blind, and Controlled Study to evaluate the Efficacy and safety of Lidocaine Infusion Treatment in Management of Neuropathic pain.
Systemic Effects of Lidocaine Infusion for TAP Block Catheter
Lidocaine is a local anesthetic that is usually used for nerve blocks to sensory/motor blockade. However, lidocaine can also been given intravenously, and it has been shown that this method can be used to help alleviate chronic pain. We wish to investigate if lidocaine is infused via the transversus abdominis plane (TAP) block catheter will exert systemic effect, hence reduce opioid consumption and pain score in patients compared with using local anesthetic such as ropivacaine.
Efficacy of Intravenous Lidocaine in the Operative Management of Thyroid Surgery With Intraoperative Nerve Monitoring
Intra operative Nerve Monitoring ( IONM ) is rapidly becoming the standard of care for thyroid surgery to prevent injury to the recurrent laryngeal nerve. However the laryngo tracheal reflexes need to be adequately suppressed to permit proper utilization of intra operative nerve monitoring. Increasing the depth of anesthesia to achieve this often leads to side effects. Intravenous lidocaine infusion has been shown to be effective in blunting these reflexes. The planned study intends to look at the efficacy of intravenous lidocaine infusion in decreasing the amount of anesthesia medications needed to suppress the reflexes. Also the study looks at the analgesic and anti emetic properties of intravenous lidocaine infusion post operatively by measuring these outcomes. The study is designed as a double blinded randomized controlled trial with 30 subjects in the group who will receive intravenous lidocaine during surgery and 30 subjects in the group who will receive placebo. Blunting of the laryngo tracheal reflexes intra operatively will be recorded as the primary outcome. The amount of anesthesia medications, the post operative patient comfort level, pain control, usage of narcotic pain medications, nausea, vomiting will be recorded as secondary outcomes.
Longterm Postoperative Analgesia, Intravenous Lidocaine Infusion

Comparison of intraoperative infusion of lidocaine and esmolol in the postoperative requirement of opioid for postoperative pain management after laparoscopic cholecystectomy to decrease opioid related side effects and enhance postoperative recovery with multimodal analgesia approach.
Lidocaine Infusion for Chronic Pain in Opioid Dependent Patients
Prescription drug abuse represents a major healthcare problem, with treatment costs reaching billions of dollars annually in the United States alone. Today opioids are commonly prescribed for chronic non-cancer pain and are only partially effective for short-term pain relief. Whereas opioids are initially part of the solution for pain, it eventually often turns to be a problem in patient with chronic pain. Long-term treatment with opioids can be complicated by development of tolerance, dependency, addiction, abnormal pain sensitivity, hormonal changes, and immune modulation. Unfortunately, the chronic use of anti-inflammatory drugs is associated with a marked increase in adverse effects. The purpose of this study is to determine whether systemic administration of lidocaine provides effective pain relief in opioid dependent chronic pain patients. Investigators intend to demonstrate that lidocaine infusion can improve pain relief and physical function in opioid dependent patients, thus improving compliance and patient satisfaction, which may potentially help wean patients off narcotics. The long-term goal of this proposal is to decrease opioid dependence in chronic pain patients by using lidocaine infusion.
(TAP) Block vs. Systemic Lidocaine: Effects on Recovery
It has been demonstrated that female patients have poor quality of surgical recovery compared to male patients. Increased sensitivity to pain and increased susceptibility to postoperative nausea and vomiting have been attributed as causal factors. Currently, few strategies have been shown to improve quality of recovery in female patients undergoing laparoscopic hysterectomy. A better recovery in female patients undergoing outpatient laparoscopy is particularly desirable since those patients do not have access to potent intravenous medications and nursing support after hospital discharge. Our group has previously demonstrated that both TAP block and systemic lidocaine improve quality of recovery after outpatient laparoscopic gynecological surgery. The TAP block, however, requires expertise, equipment (ultrasound), and additional time to perform as compared with a simple lidocaine infusion. It is currently unknown if a systemic lidocaine infusion provides non-inferior quality of recovery when compared to TAP block for outpatient laparoscopic gynecological surgery. The main objective of the current investigation is to examine the effect of TAP block on quality of recovery compared to a systemic lidocaine infusion. We hypothesize that systemic lidocaine infusion would provide non-inferior quality of recovery when compared to TAP block for outpatient laparoscopic gynecological surgery. Significance: This is the first study to compare systemic lidocaine to TAP block with regard to quality of recovery. The research question; does systemic lidocaine provide similar quality of recovery as TAP block for outpatient laparoscopy? The hypothesis; systemic lidocaine provides non-inferior quality of recovery as TAP block for outpatient laparoscopy. Research significance: It has been shown that females have poor surgical recovery compared to males; this project intends to demonstrate that systemic lidocaine provides similar recovery as TAP blocks but it does not require the expertise, equipment, and time needed to perform TAP blocks.
Intravenous Lidocaine and Quality of Recovery After Cesarean Delivery
When given intravenously, the local anesthetic lidocaine has been shown to decrease the amount of pain medication patients require when recovering from several types of surgeries. Cesarean delivery is a very common surgery in the United States, effecting more than 1 million women each year. The investigators hypothesize that lidocaine, given during and immediately after a patient undergoes a cesarean section, will help improve a mother's overall recovery experience, as well as positively influence bonding with her new baby.
Perioperative Pregabalin and Lidocaine to Reduce Chronic Breast Cancer Pain
Breast tissue and the areas surrounding the breast contain many small to medium-sized nerves. During surgery on the breast, these nerves can be inadvertently cut or damaged. Chemotherapy and radiotherapy after surgery worsen the injury experienced by these nerves. These nerves eventually become abnormal and provide pain signals to the brain well beyond the healing period after surgery. Patients with these abnormal nerves suffer from chronic pain in the breast area that persists for several years after surgery. Chronic pain is associated with a reduced quality of life, daily functioning, psychological distress, and contributes to excessive health care expenditures. There is encouraging data suggesting that an infusion of Lidocaine during surgery and Pregabalin given around the time of surgery can prevent the development of chronic pain after breast cancer surgery. A large randomized controlled trial is needed to determine the efficacy of these two interventions on reducing chronic pain after breast cancer surgery (e.g. within 3 months of surgery). A pilot trial is first needed to determine the feasibility of undertaking such a trial.
Long Term Outcome After Serial Lidocaine Infusion in Peripheral Neuropathic Pain
The purpose of this study to evaluated Long term outcome after serial Lidocaine infusion when compared with placebo in peripheral neuropathic pain patients in acute stage (less than 6 months) at 3 months after first time of infusion
Effect of Infusion of Lidocaine, Magnesium and Remifentanil Perioperatively in Patients Undergoing Mastectomy
This study aims to compare the quality of perioperative analgesia of lidocaine, magnesium sulphate and remifentanil in patients undergoing mastectomy
Effect of Perioperative Intravenous Lidocaine Infusion and Magnesium Infusion on the Functional Recovery After General Anesthesia in the Patients Undergoing Breast Mastectomy
Postsurgical pain is a relevant side effect following surgery which increases the risk of various complications and delays postoperative patient recovery. Among the many types of surgeries, mastectomy causes not only acute but also chronic pain in many patients. Therefore, it is important to control pain and increase patients' recovery satisfaction following many kinds of operations by using as small an opioid analgesic dose as possible and adding a nonopioid analgesic to reduce the side effects of narcotic analgesics. Among nonopioid analgesics, lidocaine and magnesium are drawing attention, having been shown to be helpful in controlling postoperative pain by lowering pain hypersensitivity to surgical stimuli. An intraoperative intravenous injection of lidocaine has been reported to improve postoperative pain control by reducing postoperative pain and opioid consumption. Another report showed that an intraoperative intravenous injection of lidocaine improved the quality of postoperative functional recovery after general anesthesia in a laparoscopic cholecystectomy patient. In addition, a review article on the effect of intraoperative intravenous injection of magnesium found it to be an effective analgesic that may be added to conventional opioid-based therapy because it generally reduces opioid consumption, decreases pain assessment for 24 hours after surgery, and lacks severe side effects in relation to magnesium administration. However, there has been insufficient research comparing the intraoperative intravenous injection of lidocaine or magnesium in terms of which is more helpful for general functional recovery and decreased postoperative pain. Recently, the scope of research on anesthesia has come to embrace postanesthetic recovery; to help patients return to daily life, the research trend is now shifting from the improvement or resolution of a specific symptom to the measurement of general recovery. A widely used method to measure postoperative recovery is the Quality of Recovery 40 (QoR-40) survey. Therefore, in this study, the researchers investigated the intraoperative intravenous injection of lidocaine and the intravenous injection of magnesium to compare these drugs' helpfulness in the functional recovery of mastectomy patients after general anesthesia.
Influence of Dexmedetomidine and Lidocaine on Opioid Consumption in Laparoscopic Intestine Resection
Using combination of opioid analgesics and analgesics with different mechanism of action the investigators can decrease the consumption of opioid analgesics and their side effects. The investigators will use opioid analgesic fentanyl alone or in combination with dexmedetomidine or lidocaine.The participants scheduled for laparoscopic intestine resection will be divided in three groups: in the first group, the participants will receive single boluses of fentanyl, in the second group, the participants will receive continuous infusion of lidocaine and single boluses of fentanyl, and in the third group, the participants will receive continuous infusion of dexmedetomidine and single boluses of fentanyl. Participants with intraoperative infusion od dexmedetomidine or lidocaine will need less boluses of fentanyl during the operation and less opioid analgesics after the operation in comparison to those who will receive only fentanyl boluses. Better cognitive function after the operation is expected in participants receiving dexmedetomidine infusion. There will be minimal incidence of neuropathic pain because of minimal surgical injury of peripheral nerves in all groups of patients.
Lidocaine Infusion as a Treatment for Cocaine Relapse and Craving
We propose that the systemic administration of lidocaine following the induction of cue-induced craving, relative to saline plus cue-induced craving or lidocaine without cue-induced craving, will block the reconsolidation of cue memories. This will lead to a reduction in cue-induced craving upon repeated testing as well as subsequent cocaine use and basal craving.

Systemic lidocaine infusion may improve the patients' chronic post surgical pain after video-assisted thoracic surgery
Effect of Perioperative Intravenous Lidocaine Infusion and Magnesium Infusion on the Functional Recovery After General Anesthesia in the Patients Undergoing Thyroid Surgery
Studies have attempted to control pain and increase patients' recovery satisfaction following many kinds of operations by using as small an opioid analgesic dose as possible and adding a nonopioid analgesic to reduce the side effects of narcotic analgesics. Among nonopioid analgesics, lidocaine and magnesium are drawing attention, having been shown to be helpful in controlling postoperative pain by lowering pain hypersensitivity to surgical stimuli. Lidocaine acts as an antagonist of the N-methyl-D-aspartate (NMDA) receptor. An intraoperative intravenous injection of lidocaine has been reported to improve postoperative pain control by reducing postoperative pain and opioid consumption. Another report showed that an intraoperative intravenous injection of lidocaine improved the quality of postoperative functional recovery after general anesthesia in a laparoscopic cholecystectomy patient. In addition, a review article on the effect of intraoperative intravenous injection of magnesium found it to be an effective analgesic that may be added to conventional opioid-based therapy because it generally reduces opioid consumption, decreases pain assessment for 24 hours after surgery, and lacks severe side effects in relation to magnesium administration. However, there has been insufficient research comparing the intraoperative intravenous injection of lidocaine or magnesium in terms of which is more helpful for general functional recovery and decreased postoperative pain. Recently, the scope of research on anesthesia has come to embrace postanesthetic recovery; to help patients return to daily life, the research trend is now shifting from the improvement or resolution of a specific symptom to the measurement of general recovery. Postoperative recovery is a complicated process related to such catamnestic factors as physiological end-points, the incidence of adverse events, and changes in psychological status. A widely used method to measure postoperative recovery is the Quality of Recovery 40 (QoR-40) survey. The QoR-40 includes a total of 40 questions that may be divided into five sub-categories: emotional state, physical comfort, psychological support, physical independence, and pain. The respondent answers each question on a 5-point scale, with one being worst and five being best. The QoR-40 takes 6.3 minutes on average to complete and is known to have good test-retest reliability, internal consistency, and split-half reliability. With respect to anesthetic recovery, the QoR-40 has been used in various studies to investigate how the surgery type, anesthesia method, administration of an additional drug, and gender affect anesthesia and surgery. The validity of the QoR-40 for research purposes has already been established. Therefore, in this study, we investigated the intraoperative intravenous injection of lidocaine and the intravenous injection of magnesium to compare these drugs' helpfulness in the functional recovery of thyroidectomy patients after general anesthesia.

The aim of the present study is to compare the antiarrhythmic and myocardial protective effect between lidocaine, dexmedetomidine, and their combined infusion in subjects undergoing coronary artery bypass graft.
Continuous Lidocaine Infusion for Management of Perioperative Burn Pain
Thermal injury results in one of the most intense and prolonged forms of pain the body can experience. Opioid narcotics are the most powerful drugs for acute and chronic pain, and their use in the perioperative period has been the mainstay of treatment; although medication requirements in burn patients are often underestimated. More medication may not be the answer, as relatively large doses of short acting opioids in the operative theater are associated with greater postoperative opioid consumption and higher pain scores. Furthermore, extensive use of opioids has resulted in the development of by hyperalgesia and allodynia. Lidocaine is an amide local anesthetic that has analgesic, anti-hyperalgesic, antiarrhythmic, and anti-inflammatory properties. Over the past 25 years, systemic lidocaine has been used for perioperative pain management in a variety of surgical procedures. The design of this study will examine if lidocaine will reduce the pain scores and narcotic utilization in patients undergoing surgical procedures for burn injuries. The intervention group will receive a bolus dose of lidocaine followed by a continuous infusion over 24 hours. The control group will get an equal volume of saline. The investigators will compare pain scores, opioid use, and narcotic equivalents based on body weight and burn surface area (BSA) grafted.
Perioperative Ketorolac-lidocaine in the Patients With Valvular Heart Diseases During Cesarean Delivery
Rheumatic heart valve diseases are prevalent among the young people in Egypt secondary to the socioeconomic conditions. The goal of anesthetic management of these patients is maintenance of sinus rhythm, systemic blood pressure, preload, coronary perfusion, and cardiac output. Many women still prefer general anesthesia rather than regional techniques at the author's country. The pharmacological modifications of the sympathetic response to tracheal intubation and surgical stimulation using opioids have adverse effects on the neonatal outcome after cesarean delivery. The authors have demonstrated in their previous studies the safety of both perioperative infusion of both of ketorolac and lidocaine in the attenuation of the hemodynamic and hormonal responses of tracheal intubation and surgery during cesarean delivery with favorable neonatal outcome and without added risk of perioperative bleeding. Therefore, the authors reported successful anesthetic management of a parturient with infective endocarditis on top of rheumatic mitral valve disease with use of paracetamol-lidocaine-ketorolac-propofol anesthesia. The investigators hypothesize that the perioperative use of ketorolac-lidocaine would reduce the maternal hemodynamic responses to intubation and surgery without any harmful effects on mother or baby during uncomplicated cesarean delivery in the parturients with valvular hear diseases. The investigators are aiming to compare the effects of ketorolac-lidocaine and fentanyl on surgical stress responses, intraoperative fentanyl and vasoactive drugs consumption and neonatal outcome during cesarean delivery in the parturients with valvular hear diseases.
Analgesic Efficacy of Intravenous Lidocaine for Postoperative Pain Following Adult Spine Surgery

The effect of perioperative intravenous lidocaine infusion on postoperative rehabilitation and the inflammatory response will also be examined.
NK Activity Modulation Induced by Intravenous Lidocaine During Colorectal Laparoscopic Surgery
Surgical resection is the best treatment option for colorectal cancer. Despite this radical approach, recurrences within five years are still common. Several authors have proposed that the immunosuppressive state surrounding the perioperative period was a key element of cancer cells spread. A particular subtype of T lymphocytes, the Natural Killer cells (NKs), is the main actor of the innate immune system. Several factors of the perioperative period can reduce activity of NKs such as stress, pain, opioids and general anaesthetics. Lidocaine is a local anaesthetic that has been widely used intravenously for abdominal surgeries. Intravenous lidocaine has been shown to reduce pain scores, morphine consumption, ileus time and length of stay in major colorectal surgeries. It reduced markers of systemic inflammation as well. The authors hypothesize that the use of intravenous lidocaine during laparoscopic surgeries for colorectal cancer resection will preserve NKs activity.
Subcutaneous Lidocaine For Cancer-Related Pain
This study's primary objective is to test the hypothesis that a single infusion of subcutaneous lidocaine can cause a clinically useful reduction in cancer pain within 48 hours of infusion and lasting a minimum of 7 days. A clinically useful reduction in pain is defined by either a 2-point reduction (on a 0-10 scale) in the worst pain experienced over a 24-hour period, or a ≥30% reduction in 24-hour opioid requirement. We will use a composite endpoint of reduction in pain without increase in 24-hr opioid requirement or no decrease in pain with a ≥30% reduction in 24-hour opioid requirement.Subjects will receive either lidocaine or placebo, followed at least 1 week later by the alternate agent.

This study will also aim to determine whether intraoperative lidocaine infusion during general anesthesia improves recovery and patient outcome, as well as to determine whether lidocaine infusion decreases postoperative opioid (pain medication) usage.
Peri-Operative Lidocane, Ketamine, or Lidocane and Ketamine Combination, Infusion for Patients Undergoing Spine Surgery
This study has been designed as a controlled clinical trial to evaluate the efficacy of brief lidocaine infusion, brief ketamine infusion and a lidocaine/ketamine combined infusion when added to conventional opioid therapy following major spine surgery, as well as to evaluate the effects of the lidocaine/ketamine pain protocol on the feasibility of performing routine intraoperative neurophysiology during spine surgery in adults and determine whether this infusion protocol is compatible with intraoperative neurophysiology on spine surgery patients. If one or more of the approaches is confirmed as efficacious and safe, it could have a significant impact on the routine management of postoperative pain in this context.
Ketamine, Lidocaine and Combination for Postoperative Analgesia in Open Liver Resection
Lidocaine and ketamine both are being used for perioperative analgesia. Perioperative lidocaine infusion has been shown to reduce postoperative pain and opioid consumption. Perioperative low dose Ketamine has shown improved postoperative pain and reduced opioid usage. We therefore tested the hypothesis that the combination would provide better analgesia in the milieu of intrathecal morphine.

Visual analogue scale pain scores, fentanyl consumption and the frequency at which patients pushed the button (FPB) of a patient-controlled analgesia system will be recorded at 4, 12, 24, 48 hours postoperatively.
IV Lidocaine on Postoperative Pain and QOR on Morbid Obese Patients Undergoing Bypass Surgery
Can Intraoperative systemic lidocaine decrease postoperative opioid consumption and improve quality of recovery after laparoscopic gastric bypass surgery? The hypotheses:does the use of intraoperative systemic lidocaine decrease postoperative opioid consumption and improve quality of recovery after laparoscopic gastric bypass surgery. This study has the potential to confirm an opioid sparing strategy for morbid obese patients undergoing laparoscopic gastric bypass surgery. The high incidence of obstructive sleep apnea and the increased risk of postoperative hypoxemia make the development of opioid sparing techniques in this patient population warranted.
Effect of Lidocaine and Esmolol to Improve the Quality of Recovery
The purpose of this prospective, randomized, double-blinded, active-controlled study is: To assess the effectiveness of systemic administration of lidocaine and esmolol in combination (vs. either drug alone) will result in improved postoperative outcomes for patients undergoing abdominal surgery (e.g., less pain and postoperative constipation, nausea and vomiting, faster return of bowel function, resumption of normal activities of daily living), leading to a shorten length of hospital stay, maintaining hemodynamic stability during general anesthesia, when administered as intravenous adjuvants
Lidocaine Infusion for Major Abdominal Pediatric Surgery
In this study, the investigators hypothesized that perioperative i.v. infusion of lidocaine in major abdominal pediatric surgery, may have a beneficial effect on hemodynamic and hormonal responses. Also, it could decrease the hospital stay, opioid requirement and hasten return of bowel function.

The hypothesis is that continuous lidocaine infusion during video-assisted thoracoscopic surgery (VATS) reduces morphine consumption and postoperative pain.
Lidocaine For Neuroprotection During Cardiac Surgery
The purpose of this study is to see if a drug called lidocaine prevents cognitive injury (a decline in mental abilities) after heart surgery. Lidocaine is currently FDA approved and is commonly used for treating some heart rhythm disorders and for regional anesthesia (blocking nerves). The investigators are enrolling subjects in this research project to see if lidocaine will reduce the high incidence of cognitive injury seen after heart surgery. As part of this study, the investigators will also evaluate the relationship between cognitive injury and genetic makeup and the chemical changes in the subjects blood during and after surgery.
Safety of Intravenous Lidocaine Infusions
The purpose of this study is to prospectively determine the side effects profile in adults with neuropathic pain receiving intravenous infusions of lidocaine 5 mg per kg of lean body weight, infused over 45 minutes.
Analgesic Effect of Perioperative Systemic Lidocaine in Patients Undergoing Unilateral Mastectomy Surgery
The aim of this study is to determine if perioperative systemic lidocaine administration will decrease the amount of opioid analgesics required in women undergoing mastectomy surgery. In addition, patients receiving systemic lidocaine will have a lower incidence of post-mastectomy pain syndrome. This study will have 2 groups. Participants will be randomized into one of each group. The first group will be administered the drug lidocaine prior to surgery and the second group Group B will be administered saline (salt water). This is a blinded study which means the participant will not know which group they have been assigned. The subjects participation will last 12 months (surveys post operatively).
Intravenous Lidocaine and Postoperative Outcomes After Cardiac Surgery

Participants undergoing cardiac surgery will be randomized to receive either lidocaine or placebo.
The Effect of Intravenous Lidocaine on Allodynia
The purpose of this study is to study if lidocaine, given intravenously, reduces pain.
Effect of IV Lidocaine Infusions on Pain
Our goals for this study involve using intravenous lidocaine as it is normally used in the Stanford Pain Management Center to assess the effect of intravenous lidocaine on chronic pain. Studies have been done determining the efficacy of intravenous lidocaine for treating pain but little research has been done to determine the effects of an intravenous lidocaine infusion on the different components of the pain experience. Our study will incorporate pain quality measures both before and during the infusions of lidocaine to determine changes in present pain intensity.
Lidocaine and Ketamine in Abdominal Surgery
This study is being done to determine if combined infusions of lidocaine and ketamine is better than a lidocaine or ketamine infusion alone, or to placebo in improving recovery after abdominal hysterectomy. Participants will be randomized into one of four groups. Evaluations will be done through walking tests, pain and fatigue questionnaires and blood tests.
Perioperative Intravenous Lidocaine or Epidural Anesthesia on Outcomes in Complex Spine Surgery
The purpose of this study is determine if epidural anesthesia administered after surgery or lidocaine administered during surgery will decrease inflammation after spinal surgery and decrease the need for post operative pain medication compared to intravenous patient controlled analgesia. Participants undergoing spine surgery will be randomized into one of two groups; \- A.) General Anesthesia and postoperative Patient Controlled Analgesia and placebo IV infusion. B.) General Anesthesia plus perioperative intravenous lidocaine infusion, and post operative Patient Controlled Analgesia.
Treatment of Postoperative Pain After Total Hip Arthroplasty Using Intravenous Lidocaine Infusion
This study will focus on patients undergoing total hip arthroplasty and Loma Linda University Medical Center \& East Campus. These patients will be randomized to receive a low dose lidocaine infusion or placebo, in addition to the patient controlled analgesia pump. These groups will be compared to one another statistically to determine which group shows the safest and most satisfying pain control.
Treatment of Postoperative Pain After Total Knee Arthroplasy Using Intravenous Lidocaine Infusion
Total knee replacement is often associated with severe postoperative pain, especially in the first 24 hours. Patient controlled analgesia (PCA) and continuous femoral block with PCA are commonly used to treat postoperative pain after total knee arthroplasty. However, PCAs use opioids. Opioids are excellent painkillers but their use is hampered by side effects such as nausea, vomiting, bowel dysfunction, urinary retention, pruritus, sedation and respiratory depression. We propose to test the hypothesis that adding a low dose lidocaine infusion to PCAs will lower the amount of opioids that these patients receive, thereby improving patient safety while still providing adequate analgesia. In addition, continuous femoral block has been shown to provide superior postoperative pain control when compared to morphine PCA. Therefore, postoperative pain levels of study subjects will be compared to those subjects who receive a combination of a continuous femoral block catheter with a PCA.
Lidocaine and Pain Management in First Trimester Abortions
The purpose of this study is to examine the effect of lidocaine (a numbing medication) inside the uterus on patient pain during an early abortion, compared to the paracervical block (lidocaine injected on either side of the cervix).
Intrauterine Lidocaine Infusion for Essure Sterilization Procedures
The purpose of this study is to assess the level of pain women experience with an Essure procedure and the effect that lidocaine might have on that pain. We will also assess the absorption of lidocaine in the uterus by measuring lidocaine levels in the blood.
Intraoperative Lidocaine Infusion for Analgesia (ILIA)
The purpose of this study is to evaluate the efficacy of intravenous lidocaine infusion administered during general anesthesia in: 1. Reducing length of hospital stay following total abdominal hysterectomy 2. Reducing postoperative analgesic requirement following total abdominal hysterectomy. Hypothesis: The addition of an intraoperative lidocaine infusion to a balanced anesthetic technique will result in up to 50% of patients being discharged after postoperative day 2 compared with the current 21%. Also, it will result in a 30% reduction in opiod consumption during the first 48 hours following total abdominal hysterectomy. Assumption: Patients in the intervention and control groups will be titrated to approximately equal analgesia because they will self-administer enough pain-controlling medications to make their postoperative pain experience the same. Primary outcomes: 1. Length of hospital stay 2. Total opioid use at 48 hours postoperatively Secondary outcomes. The following data will be collected and analyzed: 1. Intraoperative data: BIS scores (to control depth of anesthesia); intraoperative serum lidocaine levels; intraoperative opioid use 2. Opioid use in the recovery room 3. Patient Controlled Analgesia (PCA) morphine requirements postoperatively up to 48 hours 4. Oral pain controlling medication use up to 48 hours postoperatively if IV PCA discontinued before 48 hours 5. Verbal Analogue Scale (VAS) pain scores in recovery room and during first 2 days post-operatively 6. Incidence of side effects that can be attributed to local anesthetic toxicity 7. Incidence of nausea and vomiting and anti-emetic use up to 48 hours postoperatively 8. Time of first flatus and first bowel movement.
Intra-op Lidocaine and Ketamine Effect on Postoperative Bowel Function
Bowel function after bowel surgery is delayed (postoperative ileus)by both opiates and the surgery itself. We hypothesized that decreasing opiate use by other analgesics will speed the return of bowel function after surgery. Lidocaine and Ketamine are drugs that appear to be synergistic and do not slow peristalsis. This study is a Randomised Controlled Trial of Lidocaine Infusion Plus Ketamine Injection versus Placebo to to determine whether they will decrease opiate use and then whether decreased opiate use will speed the return of bowel function.
Intravenous Lidocaine for Fibromyalgia
The effect of intravenous lidocaine infusion on manifestations of fibromyalgia manifestations were recorded before and 4 weeks after treatment. Pain intensity was rated on a numerical scale.The combination of 240 mg intravenous lidocaine (once a week) and 25 mg amitriptyline for 4 weeks did not modify pain intensity or manifestations in patients with fibromyalgia.
Intravenous Lidocaine and Acute Rehabilitation
Background: Intravenous infusion of lidocaine may decrease postoperative pain and speed return of bowel function. The investigators therefore tested the hypothesis that including perioperative lidocaine infusion improves recovery from laparoscopic colectomy and shortens the duration of hospitalization. Methods: Forty patients scheduled for laparoscopic colectomy were randomly allocated to receive intravenous lidocaine (bolus injection of 1.5 mg.kg-1 lidocaine at induction of anesthesia, then a continuous infusion of 2 mg.kg-1.h-1 intraoperatively and 1.33 mg.kg-1.h-1 for 24 h postoperatively) or an equal volume of saline. All patients received similar intensive postoperative rehabilitation. Postoperative pain scores, opioid consumption, and fatigue scores were measured. Times to first flatus, defecation, and hospital discharge were recorded. Postoperative endocrine (cortisol and catecholamines) and metabolic (leucocytes, C-reactive protein, and glucose) responses were measured for 48 h. Data (median \[25%-75% interquartile range\] Saline vs Lidocaine groups) were analyzed using Mann-Whitney tests. P\<0.05 was considered statistically significant.
4% Intrauterine Lidocaine Infusion for Pain Management in First Trimester Abortions
Recent studies have investigated the use of local anesthetics (i.e. lidocaine, mepivacaine) to lessen the pain experienced with minor gynecologic procedures such as endometrial biopsy and office hysteroscopy. Local anesthetic injected into the uterine cavity has been demonstrated effective in some studies at decreasing patient pain associated with these intrauterine procedures at an anesthetic concentration of at least 2%. Based on this evidence, we hypothesized that an intrauterine lidocaine infusion may reduce patient pain during first trimester abortions.
