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.

Conditions

  • Lumbar Disc Herniation
  • Postoperative Pain
