Caudal analgesia for perianal surgery . A comparison between bupivacaine and diamorphine . Seventy-three patients undergoing elective perianal surgery were randomly divided into a control group , a group who received a caudal injection of 20 ml bupivacaine 0.5 % plain and a group who received diamorphine 2.5 mg in 10 ml normal saline by caudal injection ; a comparison was then made of postoperative analgesia requirements . The bupivacaine group had better analgesia than the control group for the first 8 hours , after which there was no difference . The diamorphine group had better analgesia than the control group for the first 24 hours postoperatively . Side effects were less in the diamorphine group than the control , or the bupivacaine group . In particular , 41 % of the bupivacaine group complained of some degree of urinary retention and one patient required temporary catheterisation . It is concluded that caudal diamorphine gives good postoperative analgesia for perianal operations , particularly when motor blockade is not wanted by the surgeon .
