Summary
This prospective interventional study was carried out at Liaquat National Hospital and Medical College to evaluate and compare the postoperative analgesic effects of intravenous lidocaine and magnesium sulphate in patients undergoing laparoscopic cholecystectomy. A total of 168 ASA I-II patients were enrolled and randomly allocated into two groups of 84 participants each (Group L: Lidocaine, Group M: Magnesium Sulphate) using a sealed-envelope randomization technique in a double-blind, placebo-controlled design. All patients received standardized general anesthesia with propofol, isoflurane, and atracurium, and routine postoperative care included intravenous diclofenac sodium and ondansetron. Postoperative pain was measured at 1, 6, 12, and 24 hours using the Visual Analogue Scale (VAS) to assess and compare the efficacy and duration of analgesia between the two groups. The study aimed to provide insight into the relative analgesic performance of lidocaine and magnesium sulphate, supporting improved pain management strategies following laparoscopic cholecystectomy.
