Single- Versus Two-Level ESP Block for Analgesia After Lumbar Stabilization Surgery (ESP-Lumbar)

January 15, 2026 updated by: Hatice Ayça Sarıbudak, Ankara Etlik City Hospital

Comparison Of Single- Versus Two-Level Erector Spinae Plane Block For Postoperative Analgesia In Patients Undergoing Lumbar Stabilization Surgery

Lumbar stabilization surgery is commonly associated with moderate to severe postoperative pain. Effective pain control is important to improve patient comfort, early mobilization, and recovery. The erector spinae plane (ESP) block is a regional anesthesia technique that has been increasingly used for postoperative pain management in spine surgery.

This study aims to compare the effectiveness of single-level versus two-level ultrasound-guided ESP block for postoperative pain control in patients undergoing lumbar stabilization surgery. Patients will be randomly assigned to receive either a single-level ESP block or a two-level ESP block in addition to standard analgesic treatment.

Postoperative pain scores, opioid consumption, and the incidence of side effects will be evaluated during the postoperative period. The results of this study may help determine the most effective ESP block technique for pain management after lumbar stabilization surgery.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Single Level Erector Spinae Plane Block
Participants in this arm will receive an ultrasound-guided erector spinae plane (ESP) block performed at a single vertebral level corresponding to the surgical site, in addition to standardized general anesthesia and postoperative multimodal analgesia.
Ultrasound-guided erector spinae plane block performed at a single vertebral level for postoperative analgesia.
Active Comparator: Two Level Erector Spinae Plane Block
Participants in this arm will receive an ultrasound-guided erector spinae plane (ESP) block performed at two adjacent vertebral levels, in addition to standardized general anesthesia and postoperative multimodal analgesia.
Ultrasound-guided erector spinae plane block performed at two adjacent vertebral levels for postoperative analgesia.
