异丙酚静脉麻醉联合宫颈喷淋管表面麻醉应用于无痛人工流产的研究

目的:探讨异丙酚3种麻醉方法用于无痛人工流产的效果及安全性。方法:选择停经40～70天,自愿无痛人工流产的健康妇女600名,随机分为P组,单独异丙酚静脉麻醉;P+F组,异丙酚+芬太尼静脉麻醉;P+S组,异丙酚+宫颈喷淋管表面静脉麻醉。结果:各组年龄、体重、孕产次、停经天数等均无显著差异,3种方法麻醉满意率均为100％。联合用药可减少异丙酚用量,减缓注药速度,呼吸抑制发生比率明显降低(P<0.05),但P+F组麻醉清醒后有眩晕感的人数明显多于其它两组,离院时间也相应延长(P<0.05)。P+S组与其它两组比较有明显的扩张宫颈作用(P<0.01),且术后无眩晕感。结论:异丙酚静脉麻醉联合宫颈喷淋管表面麻醉用于无痛人工流产可提高麻醉的安全性并有利于手术操作。

Study of Painless Induced Abortion Using Intravenous Transfusion of Propofol and Cervix Sprayer Surface Anesthesia

Objective: To study effects of the three kinds of anesthesia methods for painless induced abortion. Methods: 600 women in good health who asked for painless induced abortion were randomly divided into three groups. In group P(n=200) , everyone used intravenous injection of propofol only. In group P F( n=200) , everyone used intravenous injection of propofol and fentanie. In group P S( n =200) , everyone used vein anesthesia of propofol and cervix sprayer surface anesthesia. There was no obvious difference in ages, avoirdupois, gravidity among the three groups. Results: The satisfaction rate of three meth-ods all was 100%. Combining drugs could reduce amount of propofol, slow down injection speed, reduce respiratory depres-sion significantly (P < 0. 05). More women in group P F felt dizzy than ones in the other two groups, and they stayed much longer in hospital ( P < 0. 05 ). The action of cervical dilatation in group P S was significantly better than one in the other group (P <0. 01 ) , and few patient felt dizzy after operation. Conclusion: It is a safe and effective method for painless induced abortion using intravenous transfusion of propofol and cervix sprayer surface anesthesia .
