Erector spinae plane block (ESPB) is a safe and effective regional anesthesia technique in pediatric patients and can be performed at any level of the thoracic and lumbar vertebrae. In addition, ESPB can be performed at the sacral region in the midline. In pediatric patients, sacral ESPB provides effective analgesia and this method can replace caudal blocks.~This study aims to investigate the efficacy of sacral ESPB retrospectively. Demographical data of the patient, indication/surgery type, total volume applied, additional analgesic use, type of the analgesic if used will be investigated.
Patients who were operated by Department of Pediatric Surgery and who received sacral erector spinae plane blocks as a part of postoperative analgesia management will be scanned.
