Dorsal Penile Nerve Block via Perineal Approach, an Alternative to a Caudal Block for Pediatric Circumcision: A Randomized Controlled Trial

摘要

Background General anesthesia combining with a caudal block (CB) has been commonly performed in pediatric patients undergoing circumcision surgeries. However, some severe complications have been suspected of a caudal block in the combined use. To avoid these issues of a caudal block, this study introduces a novel dorsal penile nerve block (DPNB) via perineum guided by ultrasound as an alternative to a caudal block in pediatric circumcision surgeries.
