The effect of erector spinae plane block on postoperative analgesia and respiratory function in patients undergoing laparoscopic cholecystectomy: A double-blind randomized controlled trial.

Study Objective: Laparoscopic cholecystectomy (LC) causes moderate-to-severe postoperative pain. Postoperative pain is one of the leading contributors to respiratory dysfunction following surgery. This study investigated the effect of erector spinae plane (ESP) block on postoperative analgesia and respiratory function in patients undergoing LC.
