Summary

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.

  • Laparoscopic Cholecystectomy Surgery
  • Postoperative Pain Management

Interventions

DRUG

IV ketamine 0.5 mg/kg

Here is a rewritten and unbolded version of your paragraph: \--- Patients in the ketamine group were given intravenous ketamine at a dose of 0.5 mg/kg of body weight, diluted with normal saline to a total volume of 10 mL. The solution was administered as a single intravenous injection at the time of anesthesia reversal, immediately after completion of laparoscopic cholecystectomy. The drug was given under aseptic conditions by an anesthetist who was unaware of group allocation. All patients received standard postoperative care, including intravenous diclofenac sodium 75 mg every 8 hours for baseline analgesia and intravenous ondansetron 4 mg for nausea prophylaxis. Postoperative pain was assessed at 1, 6, 12, and 24 hours using the Visual Analogue Scale (VAS). Patients reporting significant pain were given intravenous Kinz 5 mg as rescue analgesia, with the timing of administration recorded.

DRUG

IV 2mg of Magnesium Sulphate

Patients in the magnesium sulfate group received 2 mg of the drug, which was diluted with normal saline to a total volume of 10 mL and administered intravenously as a single stat dose at the time of anesthesia reversal following completion of laparoscopic cholecystectomy. The injection was performed under aseptic conditions by an anesthetist who was blinded to group assignment. All participants received routine postoperative care, including intravenous diclofenac sodium 75 mg every 8 hours for baseline pain control and intravenous ondansetron 4 mg to prevent nausea. Postoperative pain intensity was measured using the Visual Analogue Scale (VAS) at 1, 6, 12, and 24 hours. Patients experiencing significant pain were given intravenous Kinz 5 mg as rescue analgesia, and the timing of administration was recorded for documentation.
