Sacral Erector Spinae Plane Block Provides Surgical Anesthesia in Ambulatory Anorectal Surgery: Two Case Reports

Abstract

Erector spinae plane block (ESPB) is a new and popular interfacial fascial plane block which has been used in many different surgeries. There are a few cases in which ultrasound-guided sacral ESPB was used for postoperative analgesia. This article presents the successful use of bi-level, bilateral sacral ESPB for main anesthetic method in anorectal surgery. Anesthetic level required for surgery was accomplished in 30 minutes, and none of the patients experienced pain throughout the surgery. The patients were discharged at the postoperative fourth hour without any complications. The patients, who were contacted later, indicated no need for any analgesic for 24 h postoperatively. To the best of our knowledge, this is the first case report in the literature where sacral ESPB is used as the sole anesthetic technique. The sacral ESPB can be considered in anorectal surgery as an alternative technique for spinal or general anesthesia.
