Intraperitoneal Ketamine Versus Bupivacaine for Postoperative Pain Control After Laparoscopic Cholecystectomy

The intraperitoneal approach is used in anesthesia to manage the pain associated with abdominal procedures. Few studies have been conducted comparing intraperitonela ketamine with bupivacaine for pain control in laparoscopic cholecystectomy (LC) patients. To compare effect of intraperitoneal ketamine versus bupivacaine for postoperative pain control after LC. Department of Anesthesiology, Critical Care and Pain Management, Liaquat National Hospital and Medical College, Karachi. Group K received ketamine whereas Group B received bupivacaine. In Group K, ketamine 0.25mg/kg diluted in normal saline to a total volume of 40 ml was instilled by the surgeon. In Group B, bupivacaine 2mg/kgdiluted in normal saline to a total volume of 40ml was administered. Tramadol 1.5 mg/kg to a maximum of 100 mg IV was given as rescue analgesia. The pain was assessed using a numeric rating scale (NRS) with zero being no pain to ten being the worst possible pain. Pain was assessed using NRS at 0 hour (immediate postoperative period), 2 hour, 4 hour, 6 hour and 12 hours postoperatively.
