Efficacy Of Low-dose Ketamine In The Management Of Peri Operative Analgesia In Patients Undergoing Abdominal Surgery

This is a prospective, randomised, controlled clinical trial designed to evaluate the effect of low-dose ketamine infusion on postoperative pain and opioid requirement in patients undergoing elective abdominal surgery under general anaesthesia. Fifty patients are randomly allocated to receive either ketamine or normal saline during surgery. Pain scores, haemodynamic parameters, total morphine consumption, recovery times, and postoperative side effects are monitored for twenty four hours. The primary aim is to determine whether ketamine reduces morphine requirement and improves postoperative analgesia compared to the control group.
