Investigational drug(s) / intervention(s)

Erector Spinae Plane BlockRhomboid Intercostal-Subserratus Plane Block

Erector Spinae Plane Block: Bilateral ultrasound-guided erector spinae plane block performed before laparoscopic cholecystectomy for postoperative analgesia.

Rhomboid Intercostal-Subserratus Plane Block: Bilateral ultrasound-guided rhomboid intercostal-subserratus plane block performed before laparoscopic cholecystectomy for postoperative analgesia.

Study summary

This prospective randomized controlled trial aims to compare the analgesic efficacy and effects on diaphragmatic function of bilateral erector spinae plane (ESP) block and bilateral rhomboid intercostal-subserratus plane (RISS) block in patients undergoing elective laparoscopic cholecystectomy. Postoperative pain scores, opioid consumption, diaphragmatic excursion, pulmonary function, and recovery outcomes will be evaluated.
