Erector Spinae Plane Block: A Newer Regional Anesthetic Technique in Spine Surgery

Abstract

The erector spinae plane (ESP) block is a relatively new regional anesthetic technique that has gained increasing attention in spine surgery. It involves the injection of local anesthetic deep to the erector spinae muscle, targeting the dorsal and ventral rami of the spinal nerves. This approach provides effective analgesia, reduces perioperative opioid consumption, and improves postoperative recovery. Compared with traditional neuraxial blocks, ESP block is technically simpler, safer, and associated with fewer complications.
