This study was designed to determine whether administration of caudal bupivacaine with fentanyl would have any effect on analgesia in paediatric patients undergoing inguinal herniorrhaphy repair. Fifty-six outpatient paediatric patients undergoing inguinal hernia repair were evaluated. Patients received, in a randomized manner, 1 of either bupivacaine 0.25% or 0.125% with or without fentanyl 1 There was no difference in pain scores in the hospital, the night of surgery, or 24 h postoperatively nor was there a difference in the oral analgesics administered between any of the groups. There was a higher incidence of vomiting at home in both 0.25% bupivacaine groups irrespective of the use of fentanyl. The 0.125% bupivacaine group had significantly more patients who received intravenous fentanyl in the PACU than did the other three groups (P<0.001). Increasing the concentration of bupivacaine from 0. 125% to 0.25% increased the incidence of postoperative vomiting. We recommend that clinicians utilize bupivacaine 0.125% with 1 microg. kg-1 fentanyl as the caudal injectate in paediatric patients undergoing inguinal hernia repair.
