Objectives: We compared the quality and duration of analgesia, the effect on perioperative sevoflurane requirement after a single, presurgical caudal block with either tramadol or morphine in children undergoing inguinal herniorrhaphy. Our study was also designed to evaluate the preemptive analgesic efficacy of morphine administered caudally in children.
