Analgesic Efficacy of Bilateral Erector Spinae Plane Block in Pediatric Tethered Cord Syndrome Surgery

Plain-language summary

Tethered Cord Syndrome is a developmental anomaly of neuroaxis characterized by stretching of the spinal cord and is diagnosed in the pediatric age group. Surgical release of the tight and tethered filum terminale is performed. Intraoperative neurophysiological monitoring (IONM) is used to preserve functional nerve tissue and prevent postoperative neurological deficits. Total intravenous anesthesia (TIVA-TCI) with propofol and remifentanil is used as the anesthesia method to ensure accurate measurements. Postoperative pain is acute pain caused by surgical trauma and signal transmission in afferent neurons. Pediatric postoperative pain is associated with adverse behaviors, prolonged hospital stay, and impaired functional recovery. Although good progress has been made in pain management, ineffective postoperative pain management in children remains a global problem. Regional anesthesia is increasingly used in pediatric patients to provide postoperative analgesia and support intraoperative anesthesia. Ultrasound-guided erector spinae plane block (ESPB) is a new approach. First introduced in 2016 by Forero et al., ESPB is a novel regional anesthesia technique that blocks the branches of spinal nerves by injecting a local anesthetic into the fascial plane between the erector spinae muscle and the transverse process. The aim of our study was to reduce intraoperative anesthetic drug consumption, postoperative pain levels in the first 24 hours, the need for analgesics, and unwanted side effects associated with analgesics by applying bilateral ESPB in pediatric patients operated on for Tethered Cord Syndrome. Our hypothesis in this study is that bilateral ESPB reduces intraoperative anesthetic drug consumption and the need for postoperative analgesia in pediatric patients operated on for Tethered Cord Syndrome.
