The Effect of Intravenous Lidocaine and Intraperitoneal Lidocaine Irrigation on Pain After Laparoscopic Cholecystectomy

Comparison of Intravenous Lidocaine and Intraperitoneal Lidocaine Irrigation for Effective Pain Relief After Laparoscopic Cholecystectomy: A Prospective, Randomized, Double-blind, Placebo-controlled Study

This prospective randomized study aims to comparison the effectiveness of intravenous lidocaine injection and intraperitoneam lidocaine irrigation on the relief of pain in patients undergoing laparoscopic cholecystectomy.

A total of 83 patients will be randomized into one of three groups (group C or group I or group P) based on Excel number generation.

Patients in group C will receive normal saline intravenous injection, and patients in group I will receive an intravenous bolus injection of 1.5 mg/kg lidocaine followed by a continuous lidocaine infusion of 2 mg/kg/hr.

Patients in group P will receive intraperitoneal lidocaine irrigation with 3.5 mg/kg lidocaine and normal saline 100cc.

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 2, 4, 8, 12, 24, 48 hours postoperatively.
