Effects of Erector Spinae Plane Block on Postoperative Pain Following Lumbar Fusion Surgery

The erector spinae plane block (ESPB) is a method for injecting local anesthesia to reduce pain related to a surgical procedure. The anesthesia is theorized to spread along the paraspinal fascia and anesthetize a larger area, resulting in patients reporting less pain and using less opioids postoperatively.

Subcutaneous anesthesia injection involves placement of local anesthesia under the skin around the surgical incision. This is thought to reduce pain from the incision site postoperatively.
