About

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.

60 participants in 2 patient groups

Single Level Erector Spinae Plane Block

Active Comparator group

Description:

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.

Treatment:

Procedure: Single-Level Erector Spinae Plane Block

Two Level Erector Spinae Plane Block

Active Comparator group

Description:

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.

Treatment:

Procedure: Two-Level Erector Spinae Plane Block
