Open Technique Erector Spinae Plane Block in Spinal Surgery

Comparison of the Effectiveness of Preoperative Ultrasound-Guided Erector Spine Plane Block and Erector Spine Plane Block Performed by the Intraoperative Surgeon in Postoperative Analgesia in Patients Undergoing Lumbar Disc Herniation Surgery

Erector spinae plane (ESP) block is an interfacial plane block with visceral and somatic analgesic activity at paraspinal muscles.ESPB has been successfully applied as a part of multimodal analgesia in treating postoperative pain in spinal surgery. However, it may be difficult or impossible to perform lumbar ESPB in obese patients or cases of increased lumbar lordosis. This study aims to investigate the effectiveness of ESPB applied by the intraoperative surgeon.
