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

Abstract

This prospective interventional study was conducted at Liaquat National Hospital and Medical College to compare the postoperative analgesic effects of ketamine and magnesium sulphate in patients undergoing laparoscopic cholecystectomy. A total of 78 ASA I-II patients were included and randomly allocated into two equal groups (39 patients in each group) using a sealed-envelope technique. One group received ketamine, while the other received magnesium sulphate, following a standardized intraoperative anesthesia protocol. All patients were provided routine postoperative medications according to institutional practice. Pain scores were recorded using the Visual Analogue Scale (VAS) at 1, 6, 12, and 24 hours after surgery. The objective of this study was to determine which drug offered better postoperative pain relief, thereby contributing to improved analgesic strategies for patients undergoing laparoscopic cholecystectomy.
