[Study of administration of buprenorphine suppository for postoperative pain relief following transvaginal hysterectomy].

Abstract

Buprenorphine suppository (BSP) has been available as an analgesic agent in Japan since 1990. It has gained considerable popularity in various clinical situations; however, its usefulness for postoperative pain relief has been controversial. The present study is addressed to postoperative pain in fifty-seven women who underwent transvaginal hysterectomy under spinal anesthesia with tetracaine and phenylephrine. We examined the analgesic effects of buprenorphine (0.4 mg) suppository. Patients were divided into four groups according to the timing of buprenorphine suppository administration: group A1, preoperative administration of BSP, n = 12; group A2, postoperative administration of BSP, n = 17; group A3, intravenous injection of 0.1 mg of buprenorphine during surgery and postoperative administration of BSP, n = 14; group C, control group, n = 14. All the patients in group C complained of pain within 24 hr. The onset time of pain after surgery was significantly longer in patients in group A1 (372 +/- 220 min) and A3 (481 +/- 161 min) than in control group C (282 +/- 97 min). The percentage of patients who did not complain of pain within 24 hr was the largest in group A3 (36%). However there were no significant differences in age, body weight, effective analgesic time, analgesic level or operation time among the four groups. Nausea and vomiting were observed in all groups: C (36%), A1 (41%), A2 (18%), and A3 (29%). From these results, we conclude that preoperative or intraoperative administration of buprenorphine is useful for control of postoperative pain; the method of administration of buprenorphine suppository needs further study.
