Ultrasound-guided erector spinae plane block versus thoracic epidural analgesia: Postoperative pain management after Nuss repair for pectus excavatum.

Aim Of The Study: Postoperative pain management is a significant challenge in patients undergoing Nuss repair for pectus excavatum chest wall deformity. Therapeutic anesthetic options primarily include patient-controlled intravenous analgesia, thoracic epidural analgesia (TEA), and cryoanalgesia. However, TEA is limited to inpatient use and both TEA and cryoanalgesia can result in neurologic injury.
