Efficacy of caudal fentanyl and ketamine on post-operative pain and neuroendocrine stress response in children undergoing infraumbilical and perineal surgery: A pilot study

Abstract

Caudal ketamine in a dose of 0.5 mg/kg provides prolonged analgesia when compared to fentanyl 1 μg/kg. Blunting of the NESR was observed in all the groups though the indicators of the response were lowest with ketamine.
