Quadratus Lumborum Block: Ultrasound-guided quadratus lumborum block performed preoperatively using local anesthetic injection at the thoracolumbar fascia for postoperative analgesia in lumbar disc herniation surgery.
Retrolaminar Block: Ultrasound-guided retrolaminar block performed preoperatively using local anesthetic injection into the retrolaminar space for postoperative analgesia in lumbar disc herniation surgery
Study summary
This study aims to compare the analgesic efficacy of quadratus lumborum block (QLB) and retrolaminar block (RLB) in patients undergoing lumbar disc herniation surgery. Both regional anesthesia techniques are increasingly used for postoperative pain management, but there is limited evidence directly comparing their effectiveness. The primary outcome is the postoperative pain score, while secondary outcomes include opioid consumption and patient satisfaction.
