1、一次性宫颈扩张棒联合笑气在人工流产术中镇痛的临床应用潘伟芳韩春艳胡铧文（深圳市南山区计划生育服务屮心518052）【摘要】目的：探讨一次性宫颈扩张棒联合笑气（氧化亚氮）在人工流产术屮镇痛的临床效果。方法：将200例实施人工流产术的妇女分成两组，观察组100例，术前5min放置一次性宫颈扩张棒；对照组100例，术前1小时于后穹窿放置米索前列醇600μg,两组术屮吸入笑气。观察两组术屮及术后镇痛效果、宫颈扩张情况、吸入笑气时限、手术前后血压和脉搏变化、副反应发生率、人均诊疗时间以及术后10天子宫
2、复旧情况。结果：观察组与对照组比较：术屮镇痛有效率分别为94%和96%;术后镇痛有效率分别为96%和58%;无阻力通过6.5号Hegar宫颈扩张器分别为97%和81%；吸入笑气时限分别为2.58和4.97min,诊疗时限分别为35min和108min，两者差异有统计学意义；人流综合征发生率均较低；观察组未发生副反应，而对照组为13%,术后10天子宫复旧均良好。结论：一次性宫颈扩张棒联合笑气对于人工流产术有良好的镇痛效果，而且术后仍然能持续镇痛，不影响子宫复旧，缩短了笑气吸入时限及诊疗时间，降低了手
3、术风险，副反应少，故值得临床使用。【关键词】宫颈扩张棒氧化亚氮人工流产镇痛【中图分类号】R714【文献标识码】A【文章编号】1672-5085（2014）02-0030-02ClinicalApplicationonPainlessInducedAbortioninArtificialAbortionforDisposableCervicalDilatorCombinedwithNitrousOxidePanWeifang，QiuXinjiao,HuHuawen.DeparmentofGyneco
