Clinical trials

The aim of this study is to evaluate the effects of non-pharmacological factors-such as age, sex, body mass index, paraspinal muscle mass, vertebral canal anatomy, patient positioning, and injection technique-on the duration of sensory and motor block in patients undergoing spinal anesthesia, and to investigate the potential relationships between these factors and block duration.

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.
