Background:
Patients undergoing spine surgery may experience substantial postoperative pain. The aim of this systematic review is to examine the clinical efficacy of a newly introduced regional anesthetic block, the erector spinae plane block (ESPB), for adults undergoing posterior spine surgeries.
Methods:
A formal systematic database search was conducted in PubMed, Ovid Medline, Embase, Cochrane library, and Google Scholar for randomized controlled trials comparing ESPB with control or placebo.
Results:
Our systematic review demonstrates a reduction of postoperative pain and opioid consumption in patients who had ESPB compared with control groups for lumbar spine surgery. However, the effect obtained revealed only a short-term benefit.
Conclusions:
Current evidence is insufficient to support the widespread use of ESPB for spine surgery. More studies are warranted to confirm or refute its role in clinical practice.
