Background and objectives: The provision of adequate analgesia is necessary after any surgery and is all the more important in children. Pain after surgery is inevitable. It has been recognized for some time that management of acute pain, especially postoperative pain, has been consistently and systematically inadequate, situation being worse in children. Bupivacaine has been for long used in caudal for post-operative analgesia but had back drop considerations of toxicity in large doses thus making it necessary to be able to use an alternative drug like Ropivacaine and levobupivacaine with lower toxicity but similar analgesic capability.
