About

The investigators aim to compare the postoperative analgesic efficacy of the classical erector spinae plane block and the modified erector spinae plane block in the management of postoperative analgesia after lumbar disc surgery.

Full description

Lumbar spinal stenosis may lead to variable signs and symptoms such as low back pain, radiating pain to the lower extremities, and reduced walking capacity. Lumbar disc surgery itself causes significant pain due to extensive dissection and muscle retraction during the procedure. A multimodal analgesic approach is preferred for postoperative pain management after lumbar spine surgery. The addition of regional anesthesia techniques reduces opioid-related side effects and is associated with earlier mobilization, shorter hospital stay, and improved patient satisfaction.

In patients undergoing lumbar disc surgery, the classical erector spinae plane block and the modified erector spinae plane block provide effective analgesia for postoperative pain control.
