Summary Forty boys aged from one to five years undergoing orchidopexy were randomly allocated to receive one of two solutions for caudal epidural injection. Group A received 1 ml??kg −1 of 0.125% bupivacaine with ketamine 0.5 mg??kg −1 and Group B received 1 ml??kg −1 of bupivacaine 0.25% with ketamine 0.5 mg??kg −1 . Postoperative pain was assessed by means of a modified Objective Pain Score and analgesia was administered if this score exceeded four. The median duration of caudal analgesia was 8 h in Group A compared with 9.5 h in Group B ( P <0.05). The time taken to recover the ability to walk was a median of two h in Group A and three h in Group B ( P <0.05). There were no differences between the groups in the incidence of urinary retention or postoperative sedation.
