[Comparison among three techniques of postoperative regional analgesia with ropivacaine in children.].

Background And Objectives: Postoperative pain increases cost and generates dissatisfaction among parents regarding to the analgesics prescribed to their children. Ropivacaine has a broad safety margin to be used for regional block in pediatric patients. The aim of this study was to compare caudal epidural block (CE) with ilioinguinal/iliohypogastric nerve block (IINB) and infiltration of surgical wound (ISW) with ropivacaine for postoperative analgesia in children.
