Efficacy and safety of erector spinae plane block for postoperative analgesia after surgery: An Umbrella review protocol

Abstract

Background: Poorly managed postoperative pain after thoraco-abdominal surgery has several consequences in the postoperative period. The postoperative pain after thoraco-abdominal surgery has been managed with systemic opioids and different regional anesthesia techniques. The erector spinae plane block is a relatively new method that is simple to perform and generally associated

with few complications. Despite these advantages, the strength of the evidence supporting its effectiveness remains limited, and further studies are needed to confirm its clinical value.

Objective: This systematic review aimed to provide the quality of evidence on the efficacy and safety of erector spinae block after surgery.

Method: A comprehensive search was carried out in PubMed/Medline, Cochrane, Science Direct, CINHAL, and LILACS without restrictions on date or language. Only randomized trials assessing wound infiltration for postoperative pain after cesarean section were included, while observational studies and reviews were excluded. Data extraction was performed independently by two authors using a tailored format. Study quality was assessed with the AMSTAR tool, and overall evidence strength was rated through GRADEpro. The review followed PRISMA guidelines for systematic reviews and meta-analyses.

Discussion: Postoperative pain is common after thoraco-abdominal surgery and places a heavy burden on patients, families, and healthcare systems. This review evaluates the effectiveness and safety of both landmark-guided and ultrasound assisted erector spinae plane block techniques for managing pain after surgery.
