Quadratus Luborum Block Using Bupivacaine Versus Bupivacaine-Dexamethasone in Laparoscopic Cholecystectomy

The aim of the present study was to compare the effectiveness of transmuscular Quadratus Lumborum block using Bupivacaine versus Bupivacaine- Dexamethasone in providing analgesia in patients undergoing laparoscopic cholecystectomy. Because postoperative pain after laparoscopic surgery is complex, specialists suggest that effective analgesic treatment should be a multimodal support. Quadratus lumborum block (QLB) is a new abdominal truncal block for controlling somatic pain in both the upper and lower abdomen. Dexamethasone, through its anti-inflammatory and blocking effects on neural discharge, and nociceptor C fibers transmission could be used as a local anesthetic adjuvant.
