The Effect of Quadratus Lumborum Block vs Erector Spinae Block in Postoperative Analgesia in Patients Undergoing Laparoscopic Cholecystectomy

Abstract

Abstract Background However, the postoperative pain following laparoscopic cholecystectomy consists of both somatic and visceral components with pain originating from port entry wounds, gallbladder resection and abdominal insufflation that leads to peritoneal distention and peritoneal damage. Aim of the Work to compare analgesic efficacy of Quadratus lumborum block versus erector spinae block in postoperative analgesia in patients undergoing laparoscopic cholecystectomy. Study Design prospective randomized controlled clinical trial Methods This prospective randomized controlled clinical trial was conducted at operative theatres, Anesthesiology, Intensive Care and Pain Management Department, Faculty of Medicine, Ain Shams University Hospitals from March until August 2023. During this study, 80 patients electively scheduled for laparoscopic cholecystectomy were enrolled and divided into two equal groups; group A subjected to quadratus lumborum block and group B subjected to erector spinae block. Intraoperative, Post Anaesthesia Care Unit and postoperative haemodynamic, postoperative VAS score, first time of postoperative analgesic request, total amount of postoperative analgesia, time needed for postoperative mobilization and side effects of study procedures were evaluated. Results In this study there was no significant difference between the two groups as regards VAS score. In this study there was no significant difference between the two groups according to total amount of analgesia needed post operatively. In this study there was no significant difference between the two groups according to total amount of analgesia needed post operatively. In this study time needed for mobilization was insignificant different between two groups. In this study, no statistically significant disparity was observed between the two groups in terms of side effects. In this study, no significant difference was found between the two groups according to the first time postoperative analgesia. Conclusion This study showed comparable effect of both QLB and ESPB in patients undergoing laparoscopic cholecystectomy.
