Single- Versus Two-Level ESP Block for Analgesia After 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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • ASA I-II-III,
  • BMI:18-40,
  • Patients undergoing lumbar stabilization surgery involving 2 to 4 vertebral levels
  • Patients who personally provide written informed consent to participate in the study

Exclusion criteria

  • Patients with chronic pain conditions
  • Patients with a history of chronic opioid use
  • Patients undergoing emergency lumbar stabilization surgery

Treatment and study plan

Single-Level Erector Spinae Plane Block

Procedure

Ultrasound-guided erector spinae plane block performed at a single vertebral level for postoperative analgesia.

Two-Level Erector Spinae Plane Block

Procedure

Ultrasound-guided erector spinae plane block performed at two adjacent vertebral levels for postoperative analgesia.

Primary outcomes

  1. Intraoperative Remifentanyl Consumption

    Time frame: During the intraoperative period

    The amount of Remifentanyl that patients need to maintain anesthesia during the intraoperative period will be recorded

Secondary outcomes

  1. Pain Scores

    Time frame: First 24 hours after surgery

    Pain will be assessed at rest and while movement using the from 0 ( no pain) to 10 (worst pain). Pain assessment will be done at the 1st, 2nd, 4th, 12th and 24th hours after surgery
