Postoperative pain control by ultrasound guided brachial plexus block reduces emergence delirium in pediatric patients

Background: Pediatric patients awakening from general anesthesia may experience emergence delirium (ED), often due to inadequate pain control. Nerve block completely inhibits innervation of the surgical site and is superior to systemic analgesics. This study assessed whether pain control through nerve block relieves ED after general anesthesia.
