Intraoperative Intravenous Lidocaine for Pain After Laparoscopic Appendectomy (LIDO-APP)

Description détaillée
Postoperative pain following laparoscopic appendectomy remains an important clinical concern despite advances in multimodal analgesia. Intravenous lidocaine has been proposed as an effective adjunct because of its analgesic, anti-inflammatory, and antihyperalgesic properties, but evidence in laparoscopic appendectomy remains limited.
This prospective, randomized, double-blind, placebo-controlled trial compared continuous intraoperative intravenous lidocaine infusion with placebo in patients undergoing laparoscopic appendectomy under standardized general anesthesia. Patients were randomly allocated to receive either lidocaine or placebo according to the study protocol.
The primary outcome was postoperative pain intensity measured using the Visual Analogue Scale (VAS). Secondary outcomes included opioid requirements, postoperative nausea and vomiting, return of bowel function, length of hospital stay, incidence of adverse events, and perioperative plasma lidocaine concentrations measured at predefined intraoperative and postoperative time points.
The study aimed to determine the clinical efficacy and safety of intravenous lidocaine infusion as part of multimodal perioperative analgesia for laparoscopic appendectomy and to correlate analgesic effects with measured plasma lidocaine concentrations.

Intervention / Traitement |
|---|---|
|
Expérimental: Intravenous lidocaine group
Participants received intraoperative intravenous lidocaine infusion in addition to standardized general anesthesia according to the study protocol.
|
Intravenous lidocaine administered as a bolus followed by continuous infusion during laparoscopic appendectomy according to the study protocol.
|
|
Comparateur placebo: Placebo group
Participants received an equivalent volume of normal saline placebo under identical anesthetic conditions.
|
Intravenous isotonic saline administered using the same infusion schedule as the active treatment to maintain blinding.
