Comparison of the Analgesic Efficacy of Lumbar Erector Spinae Plane Block and Sacral Erector Spinae Plane Block in Lumbar Microdiscectomy Surgeries

Study Overview

Status

Completed

Conditions

Detailed Description

Postoperative pain is commonly observed in patients undergoing lumbar microdiscectomy surgery.

To manage this pain, the lumbar erector spinae plane (ESP) block is frequently administered as part of a multimodal analgesia regimen, particularly with the aim of reducing opioid consumption in these patients.

Recent publications have demonstrated the analgesic efficacy of the sacral erector spinae plane block in lumbar microdiscectomy surgeries.

In this study, the postoperative analgesic effectiveness of the lumbar ESP block-performed two vertebral levels above the surgical site-will be compared with that of the sacral ESP block-performed two vertebral levels below the surgical site.

It is anticipated that this approach will provide effective analgesia while avoiding the use of opioids.
