Analgesic Outcomes of Ultrasound-Guided QLB vs TAP Block in Midline Laparotomy
This randomized controlled trial compares the analgesic efficacy of ultrasound-guided bilateral lateral quadratus lumborum block (QLB, QL1) versus ultrasound-guided bilateral transversus abdominis plane (TAP) block in adults undergoing elective midline laparotomy under general anesthesia. The primary focus is postoperative pain intensity, time to first rescue analgesia, proportion requiring rescue analgesia, and total opioid consumption in the first 24 hours.
