氧化亚氮、利多卡因联合用于人工流产镇痛的临床观察

The clinical observation on the analgesia effect of Nitrous oxide combined with Lidocaine for induced abortion

目的比较氧化亚氮联合利多卡因和氧化亚氮单用时在人工流产术中的镇痛作用及软化宫颈等临床效果。方法将320例孕40～70d无阴道分娩史的妇女随机分为氧化亚氮、利多卡因联合镇痛组(观察组)和单用氧化亚氮镇痛组(对照组)各160例。观察组术中吸入氧化亚氮,并于宫颈注射2%利多卡因5ml。对照组仅给予氧化亚氮吸入。结果观察组镇痛效果、软化宫颈与对照组比较,差异均有非常显著性(P<0.01);不良反应发生率无统计学差异(P>0.05)。结论氧化亚氮联合利多卡因用于人工流产术中安全、简便,镇痛效果比单用氧化亚氮更好。

Objective To compare the analgesia effect and cervical relaxation of Nitrous oxide single - used with Nitrous oxide combined with Lidocaine applied on the induced abortion. Methods The 320 cases without the history of vaginal delivery were divided into the observation group that there was 160 - case given Nitrous oxide combined with Lidocaine with cervical injection and control group that there was 160 - case given Nill-ous oxide single - used. Results There was significant difference on the analgesia effect and cervical relaxation between two groups （P 〈0.01 ）. While there was no difference on the incidence of adverse reactions. Conclusion It was safer and simpler of Nitrous oxide combined with Lidocaine than that of Nitrous oxide single - used.
