About this trial
This prospective randomized controlled study aims to evaluate the effects of preoperative ultrasound-guided erector spinae plane (ESP) block combined with low-flow anaesthesia on postoperative quality of recovery and opioid consumption in patients undergoing elective laparoscopic cholecystectomy. The study will compare postoperative recovery quality, pain scores, analgesic requirements, and perioperative outcomes between patients receiving ESP block with low-flow anaesthesia and those receiving standard anaesthetic management.
