Non-efficacy of ultrasound-guided erector spinae plane block in postoperative analgesia of non-instrumented spine surgery: a randomized, double-blind, controlled trial.

ABSTRACT:

Introduction

Postoperative pain management is a challenge after lumbar spine surgery. Erector spinae plane (ESP) block is one solution and seems to limit opioid consumption after lumbar fusion. This RCT explored the effectiveness of ESP block versus placebo in non-instrumented spine surgery within an ERAS program.

Research question

The hypothesis suggested the superiority of ESP block across all endpoints, emphasizing its potential as a safe and effective element.

Material and methods

In this prospective, single-center, randomized, double-blinded controlled trial using a 1:1 allocation with an intent-to-treat, patients undergoing non-fusion lumbar surgery for one or two levels were included from January to November 2022. Ultrasound-guided ESP block was performed by an
