KETAMINE FOR CAUDAL ANALGESIA IN CHILDREN: COMPARISON WITH CAUDAL BUPIVACAINE

Abstract
Fifty children undergoing inguinal herniotomy were allocated randomly to three groups to receive a caudal injection of either 0.25% bupiv-acaine 1 ml kg−1 with or without ketamine 0.5 mg kg−1 or ketamine 0.5 mg kg−1 with normal saline 1 ml kg−1. There was no significant difference in quality of pain relief, postoperative behaviour or analgesic requirements between the ketamine group and the two other groups. The bupivacaine-ketamine mixture provided better analgesia than the bupivacaine solution alone. Side effects such as motor weakness or urinary retention were not observed in the ketamine group.
