【摘要】 目的 探索和研究宫腔镜检查中CO 2 流量的大小对宫腔图像的影响以及患者所出现的不良反应。 方法 以340例宫腔镜检查患者为对象，随机分为试验组(138例)和对照组(202例)。试验组以8～15ml/min的CO 2 流量膨宫，对照组以60～70ml/min流量膨宫。 结果 试验组与对照组在宫腔气泡产生数量方面、患者在检查的30min内出现的不良反应和CO 2 总用量方面，差异均有显著性。经χ 2 检验结果显示:P<0.005，差异有显著性。 结论 小流量CO 2 膨宫具有减少宫腔气泡产生率，增加宫腔图像清晰度，减少对患者所产生的不良反应，减少CO 2 用量，安全实用等优点。

    【Abstract】 Objective To approach and research the effects of CO 2 flux on the uterine cavity image quality during hysteroscope examining and the side effects to the patients.Methods 340patients who were taken hystero-scope check were divided into experiment group(138cases)in which8～15ml/min CO 2 flux was used to expand u-terine cavity and control group(202cases)in which60～70ml/min CO 2 flux was used to expand uterine cavity.Re-sults There were significant differences in the amount of air bubble in uterine cavity ......
