连续硬膜外麻醉镇痛在中期妊娠引产中应用

Application of continuous epidural anesthesia in the midtrimester induction of labor

目的探讨连续硬膜外麻醉镇痛在中期妊娠引产中的临床效果。方法行中期妊娠引产孕妇80例,依据自愿原则实施分娩镇痛40例为镇痛组,未行分娩镇痛40例为对照组。采用视觉模拟评分法(visual analogue scale,VAS)观察2组疼痛程度,比较2组产程时间、产后出血量及不良反应发生率。结果镇痛组分娩过程中VAS评分[(2.5±1.1)分]低于对照组[(7.7±1.5)分](P<0.05),产程时间[(7.1±2.5)h]、产后出血量[(135.3±25.2)mL]和不良反应发生率(2.5%)与对照组[(7.6±2.8)h、(143.2±24.9)mL、7.5%]比较差异无统计学意义(P>0.05)。结论连续硬膜外麻醉镇痛用于中期妊娠引产安全、有效,对产程、产后出血量无明显影响。

Objective To investigate the clinical effect of continuous epidural anesthesia analgesia on the midtrimester induction of labor. Methods Eighty women undergoing midtrimester induction of labor were divided into analgesia group and non-analgesia group according to the principle of voluntary labor analgesia, with 40 women in each group. Visual analogue scale （VAS） was used to observe the pain degree in both groups to compare the labor time, the amount of postpartum hemorrhage and the incidence of adverse reactions. Results The VAS score was significantly lower in analgesia group （2.5± 1. 1） than that in non-analgesia group （7. 7± 1. 5） （P〈0.05）, and there were no significant differences in labor time, the amount of postpartum hemorrhage and the incidence of adverse reactions between analgesia group （（7.1±2.5） h, （135. 3±25.2） mL, 2.55） and non-analgesia group （（7.6±2.8） h, （143.2±24.9） mL, 7.5%） （P〉0.05）. Conclusion Continuous epidural anesthesia is safe and effective for midtrimester induction of labor, and has no obvious influence on labor process or the amount of postpartum hemorrhage.
