Regional Anesthesia for Spine Surgery.

Current advancements in spine surgery have led to a recent interest in regional anesthesia for spine surgery. Spinal anesthesia, epidural anesthesia, and their combination are commonly used modalities for regional anesthesia in spine surgeries. The successful use of regional anesthesia has led to the emergence of several new concepts such as awake spinal fusion and outpatient spinal surgery. Regarding analgesic techniques, several new modalities have been described recently such as erector spinae and thoracolumbar interfascial plane blocks. These regional analgesic modalities are aimed at decreasing perioperative pain and enhancing early recovery in patients undergoing spine surgery. This narrative review focuses on the techniques, indications and contraindications, benefits, and complications of regional anesthesia in the context of spine surgery.
