目的:探讨利多卡因宫颈注射、笑气吸入、芬太尼与异丙酚联合静脉麻醉下行人工流产术中镇痛效果及宫颈扩张效果。方法:将2003年1月～2005年12月在本院门诊要求行无痛人工流产的早孕妇女376例分三组:一组宫颈注射利多卡因后行人工流产,为利多卡因组。一组笑气吸入后行人工流产,为笑气组。一组芬太尼与异丙酚联合静脉麻醉后行人工流产,为异丙酚组。比较3种方式下人工流产时镇痛效果、宫颈扩张效果及人流综合征发生率。结果:利多卡因组术中镇痛有效率65.1%,宫颈扩张有效率82.5%,人流综合征发生率22.2%。笑气组术中镇痛有效率74.6%,宫颈扩张有效率87.3%,人流综合征发生率13.6%。异丙酚组术中镇痛有效率100%,宫颈扩张有效率96.9%,人流综合征发生率2.6%。结论:芬太尼与异丙酚联合静脉麻醉下行人工流产术中镇痛效果及宫颈扩张效果均优于宫颈注射、笑气吸入下行人工流产术,且人流综合征发生率明显降低。
Objective: To investigate the analgesic effect and cervical dilation effect of lidocaine cervical injection, nitrous oxide inhalation, fentanyl and propofol combined with intravenous anesthesia in artificial abortion. Methods: From January 2003 to December 2005, 376 pregnant women with painless induced abortion in our hospital were divided into three groups: one group was treated with lidocaine, and the other group was given lidocaine. After a series of nitrous oxide inhalation abortion, as a laughing gas group. A group of fentanyl and propofol intravenous anesthesia after abortion, the propofol group. The analgesic effect, cervical dilatation effect and the incidence of abortion syndrome during abortion were compared between the three methods. Results: The effective rate of intraoperative analgesia was 65.1% in the lidocaine group, 82.5% in the cervical dilation and 22.2% in the flow syndrome. Analgesic group analgesia effective rate 74.6%, cervical dilatation effective rate 87.3%, the incidence of flow syndrome 13.6%. Intraoperative propofol analgesia effective rate of 100%, effective cervical dilatation 96.9%, the incidence of flow syndrome 2.6%. Conclusion: Analgesic effect and cervical dilation effect of fentanyl and propofol combined with intravenous anesthesia are better than that of cervical injection and nitrous oxide inhalation, and the incidence of abortion syndrome is significantly reduced.
