The Efface of Ketamine vs. Lidocaine in the Management of Pain After Laparoscopic Cholecystectomy

Abstract

This prospective interventional study conducted at Liaquat National Hospital and Medical College compared the analgesic efficacy of ketamine and lidocaine in managing postoperative pain after laparoscopic cholecystectomy. Total of 76 ASA I-II patients were randomly assigned into two equal groups (Group K: Ketamine, Group L: Lidocaine) using a sealed-envelope method in a double-blind, placebo-controlled design. Standard anesthesia with propofol, isoflurane, and atracurium was administered, and all patients received postoperative diclofenac sodium and ondansetron. Pain intensity was assessed using the Visual Analogue Scale (VAS) at 1, 6, 12, and 24 hours postoperatively. The study aimed to compare the pain-relieving effects of ketamine and lidocaine, contributing to improved strategies for postoperative pain management following laparoscopic cholecystectomy.
