Intravenous lidocaine enhances the efficacy of ondansetron and dexamethasone in postoperative vomiting prophylaxis among high-risk children.

Scientific reports •

A combination of dexamethasone, ondansetron, and total intravenous anaesthesia (TIVA) is recommended as prophylaxis for preventing postoperative vomiting (POV) in high-risk children. Implementing TIVA in paediatric patients undergoing anaesthesia presents challenges due to its excessive inter-individual variability and difficult estimation. Regarding lidocaine's antiemetic effect in paediatric patients, incorporating lidocaine can mitigate POV in high-risk children. Among 204 children undergoing elective tonsillectomy (with/without adenoidectomy), those with postoperative vomiting score ≥ 4 was randomised into Group C (saline) and Group L (lidocaine). The primary outcome was POV incidence within the first 24 h after surgery. The POV incidence differed among 15 patients in Group C (14.7%) and 5 in Group L (4.9%) presenting with one or more episodes of POV (P = 0.019). The secondary outcome was the number of coughs within the first 30 min after surgery. The number of coughs within the first 30 min after surgery significantly differed between Group L (0 [0-0.125]) and Group C (1 [0-2]) (P = 0.007). Significant between-group differences in the time to extubation were also observed, with a 3-min longer time in Group L. A lower percentage of patients experienced adverse events in Group C (2.2%) compared with Group L (1.1%) (P = 0.567); no severe events occurred. Adding intravenous lidocaine to ondansetron and dexamethasone was effective in reducing the POV incidence and extubation coughs in high-risk children following volatile anaesthesia for tonsillectomy.

Lidocaine and risk of postoperative vomiting in children undergoing tonsillectomy: a randomised clinical trial.

Scientific reports •

The dose-response of intravenous lidocaine in preventing postoperative vomiting (POV) in children remains unclear. This study investigated whether intravenous lidocaine dose-dependently decreased POV risk within 24 h postoperatively in children undergoing tonsillectomy (with or without adenoidectomy) without severe complications. Patients aged 3-12 years (American Society of Anesthesiologists grade I-II) scheduled for elective tonsillectomy (with or without adenoidectomy) were enroled from December 2021 to March 2022. They were randomly grouped according to the lidocaine dose (A [0 mg kg], B [1 mg kg], C [1.5 mg kg], and D [2 mg kg]) and were administered the same induction protocol (sufentanil, propofol, and suxamethonium chloride). Anaesthesia was maintained with sevoflurane. The incidence of POV within 24 h postoperatively was 46, 40, 36, and 20% in groups A, B, C, and D, respectively, with significant differences between groups D and A. Postoperative analgesic rescues in groups A, B, C, and D were 62, 36, 34, and 16%, respectively, with significant differences between groups D and B, C and A, and D and A. No severe adverse events were reported. Intravenous lidocaine has a dose-dependent effect on reducing the risk of POV in children undergoing tonsillectomy (with or without adenoidectomy) without serious adverse events.Trial registration: Chinese Clinical Trial Registry, ChiCTR2100053006.
