About this study
Official title: Analgesic Efficacy of Bilateral Erector Spinae Plane Block in Pediatric Tethered Cord Syndrome Surgery: A Prospective, Randomized Controlled Trial
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.
Read the detailed description
Ultrasound-guided erector spinae plane block (ESPB) that aims for the ventral and dorsal rami of the spinal nerves was recently introduced in spine surgery to treat postoperative pain. ESPB was reported to be effective in scoliosis surgery as it reduced the need for analgesic drugs. Due to its relative technical simplicity, the main advantages postulated for the ESPB are few complications and minimal risk for spinal cord injury.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
UNDER ULTRASOUND GUİDANCE ESPB BLOCKDevice
Also called ESPB BLOCK
In the ESP Block group, with the patient in the prone position, the research anesthesia team will insert a block needle through the skin one level above the surgical level using a linear probe guided by USG. The needle will pass through the trapezius and erector spinae muscles, and upon reaching the transverse process (approximately 2-3 cm deep), a test dose of 0.5-1 mL of 0.9% NaCl will be applied between the erector spinae fascia and the vertebral transverse process to confirm needle placement. After confirmation of fascial opening, a local anesthetic volume of 2 mL per vertebral pressure will be calculated, not exceeding a maximum dose of 2 mg/kg of 0.5% bupivacaine. This total volume will be diluted by half with 0.9% NaCl solution to prepare a 0.25% bupivacaine concentration. The calculated local anesthetic solution will be applied to the erector spinae region for ESPB. The same procedures will be performed on the opposite side.
PROCEDURE/SURGERY: ERECTOR SPİNAE (ESP) BLOCK WİTH BUPİVACAİNEProcedure or surgery
Also called PLANE BLOCKS
For the ESP Block group, under USG guidance with the patient in prone position, a linear probe will be placed in the parasagittal plane one level above the operative level, and after visualizing the transverse process with an in-plane approach, a 50 mm long block needle will be inserted through the skin. A test dose of 0.5-1 mL of 0.9% NaCl will be administered between the erector spinae fascia and the transverse process of the vertebra to confirm needle placement. After confirming that the fascia has opened, a local anesthetic volume of 2 mL per vertebral pressure will be calculated, not exceeding a maximum dose of 2 mg/kg of 0.5% bupivacaine. This total volume will be diluted halfway with 0.9% NaCl solution to prepare a 0.25% bupivacaine concentration. The calculated local anesthetic solution will be administered to the erector spinae area, and ESPB will be performed. The same procedures will be performed on the opposite side.
