Abstract

In relief of postoperative pain, the value of epidural or subdural injection of opioids including morphine, methadone, petidine and fentanyl is now well established. The advantages of epidural or subdural over parenteral opioids is prolonged duration of analgesia, which last from several hours to several days, without sympathetic and motor blockade. But undesirable side effects include pruritus, urinary retention, delayed onset of somnolence, and cardiovascular and respiratory depression. To reduce postoperative pain, we evaluated the effects of caudal pentazocine 0.2-0.4 mg/kg with lidocaine 1.5% 400 mg for perianal surgery in 36 cases. The results were as follows: 1) There was no difference in analgesic onset between the Control Group (used lidocaine only) and Group A and B (mixed use of lidocaine and pentazocine: Group A, 0.2 mg/kg pentazocine; Group B, 0.4 mg/kg) 2) Mean duration of analgesia following caudal pentazocine and lidocaine injection was over 12 hours, but was less than 5 hours in the used lidocaine only. 3) Urinary retention was observed in all groups; 3 case in the Control group, and 4 cases in Group A and B. 4) In Group A and B, 6 cases had not used analgesics within 24 hours after caudal anesthesia. 5) No specific clinical changes were noted in the vital signs in all groups.
