A comparison between ilioinguinal-iliohypogastric nerve block performed by anaesthetist or surgeon for postoperative analgesia following groin surgery in children.

A study was performed to compare postoperative analgesia in children undergoing groin surgery. Patients were randomly allocated to receive ilioinguinal-iliohypogastric (I-I) nerve blocks using 0.25% plain bupivicaine (0.5 ml.kg-1) performed either percutaneously by the anaesthetist after the induction of general anaesthesia, before surgery commenced, or intraoperatively, under direct vision, by the surgeon. Analgesia was assessed by pain scoring in the recovery room and at hourly intervals for eight h postoperatively. Analgesic requirement was also noted. Statistical analysis of the results revealed no difference in pain score between groups treated either by anaesthetist or surgeon. However, children under two years of age had significantly higher pain scores than those over two.
