Posterior Quadratus Lumborum Block versus Subcostal Transversus Abdominis Plane Block in Laparoscopic Cholecystectomy

Abstract

Background and objectives: Effective perioperative an-algesia with laparoscopic cholecystectomy enhances early recovery, ambulation, and discharge. Subcostal TAP block has been shown to reduce perioperative opioid use and provide effective perioperative analgesia. Currently, the QLB is performed as one of the perioperative pain management procedures for patients undergoing abdominal surgery. In the current study, we hypothesized that the analgesic efficacy of posterior QLB would be equal to or better than the subcostal TAP block in laparoscopic cholecystectomy.
