Randomized Controlled Trial
Anterior Quadratus Lumborum Block at Lateral Supra-arcuate Ligament vs Lateral Quadratus Lumborum Block for Postoperative Analgesia after Laparoscopic Colorectal Surgery: A Randomized Controlled Trial.
Quadratus lumborum block (QLB) has been found to be advantageous for laparoscopic colorectal surgery. This study hypothesized that preoperative anterior QLB at lateral supra-arcuate ligament (QLB-LSAL) would decrease postoperative opioid usage and offer improved analgesia within the context of multimodal analgesia compared with lateral QLB (LQLB) for laparoscopic colorectal surgery. ⋯ Preoperative bilateral ultrasound-guided QLB-LSAL reduces morphine usage and extends the duration until the first patient-controlled analgesia demand within the framework of multimodal analgesia when compared with LQLB after laparoscopic colorectal surgery.
