Dexmedetomidine for ESPB in Pain Management After Pediatric Idiopathic Scoliosis Surgery

This study proposes to explore the effect of perineurial Dexmedetomidine on the duration of erector spinal plane block for pediatric idiopathic scoliosis surgery. Children need good analgesia after scoliosis surgery. Peripheral nerve blocks have provided a safe, effective method to control early postoperative pain when symptoms are most severe. The safety of local anesthesia is essential in children due to the much lower toxicity threshold of local anesthetics. An effective adjuvant, such as Dexmedetomidine, could allow for a higher dilution of local anesthetics while maintaining and enhancing their analgesic effect.
