连硬外麻醉子宫切除６０例。随机分为丁组（丁丙诺啡组，ｎ＝３０）和吗组（吗啡组，ｎ＝３０）。术毕分别经导管一次性注入丁丙诺啡０．１５ｍｇ和吗啡２ｍｇ。术后比较两组间镇痛效果、不良反应和两组中出现与未出现瘙痒者的镇痛效果。结果：术后８，１２小时，丁组ＶＡＳ明显低于吗组（Ｐ＜０．０５）。至术后２４小时丁组才达到吗组８，１２小时水平。从本组资料分析丁丙诺啡０．１５ｍｇ的镇痛时间和不良反应均优于吗啡组，瘙痒与镇痛间似存在某种平行关系。
Combined with external anesthesia hysterectomy 60 cases. Randomly divided into groups (buprenorphine group, n = 30) and the group (morphine group, n = 30). At the end of surgery, buprenorphine 0.15 mg and morphine 2 mg were injected through the catheter once. Postoperative analgesic effect between the two groups, adverse reactions and two groups of patients with and without itching analgesic effect. Results: At 8 and 12 hours after operation, VAS in group D was significantly lower than that in group B (P <0.05). Twenty-four hours after operation did the group reach the level of 8,12 hours. From this group of data analysis of buprenorphine 0.15mg analgesic time and adverse reactions were better than morphine group, itching and analgesia may exist some parallel relationship.
