Regional Anesthesia for Spine Surgery.

Recent advancements in spine surgery anesthesia techniques and pain management has led to a paradigm shift from conventional open spinal procedures to minimally invasive spine surgeries performed on an outpatient basis. Spinal anesthesia and epidural anesthesia alone or in combination with spinal are common regional anesthesia modalities used in spine surgeries. New modalities of regional analgesia have emerged recently including erector spinae and thoracolumbar interfascial plane block, aimed at decreasing perioperative pain and enhancing early recovery in patients undergoing spine surgery. In this narrative review we discuss the characteristics of regional anesthesia including its types, indications, contraindications, benefits, and potential complications along with new modalities of regional analgesia.
