The analgesic efficacy of bilateral ultrasound - guided quadratus lumborum block in patients undergoing laparoscopic cholecystectomy
Main Article Content
Abstract
This study aimed to evaluate the analgesic efficacy of bilateral ultrasound-guided quadratus lumborum block (QLB) for patients undergoing laparoscopic cholecystectomy. This was a single-blind, controlled intervention study on 80 patients who underwent laparoscopic cholecystectomy at Hanoi Medical University Hospital from June 2025 to October 2025. The patients were randomly divided into two groups: the bilateral quadratus lumborum block group and the trocar site infiltration group. The study variables included intraoperative and postoperative opioid consumption, VAS pain scores while in action and at rest, the incidence of postoperative nausea and vomiting (PONV), and heart rate and blood pressure before, during, and after surgery. The results showed that the group receiving bilateral quadratus lumborum block used less intraoperative fentanyl (147.50mcg vs. 236.25mcg), had less postoperative morphine consumption (0.58mg vs. 1.53mg), and had significantly lower mean postoperative VAS scores during movement and at rest (p < 0.05) compared to the group receiving trocar site infiltration.
