目的:探讨一种简单而有效的人工流产术中镇痛方法。方法:孕6~12周,要求终止妊娠的健康妇女160例,随机分为两组,麻醉组用2%利多卡因宫颈旁阻滞麻后行人工流产术,对照组不用辅助药物。结果:镇痛效果、宫颈松弛程度麻醉组总有效率分别为94%、91%,对照组分别为58%、33%.人流综合征发生率两组分别为2.0%和8.3%,对比均有显著性差异(P<0.01),两组术后宫缩幅度及出血量对比均无显著性差异(P>0.05)。结论:2%利多卡因宫颈旁阻滞麻是一种操作简单而有效的镇痛方法。
Objective: To explore a simple and effective analgesia in induced abortion. Methods: Six to 12 weeks pregnant, 160 healthy pregnant women requiring termination of pregnancy were randomly divided into two groups. The patients in the anesthesia group were treated with 2% lidocaine and cervical paralysis followed by artificial abortion, and the control group without adjuvant drugs. Results: The total effective rate of analgesic effect and cervical relaxation were 94% and 91% respectively in the anesthetic group and 58% and 33% in the control group respectively. There was significant difference between the two groups (2.0% vs 8.3%, respectively) (P <0.01). There was no significant difference in the contractions rate and bleeding between the two groups P> 0.05). Conclusion: 2% lidocaine cervical paraquat is a simple and effective method of analgesia.
