晚期妊娠米索前列醇引产出现过强宫缩的对策

目的：探讨晚期妊娠米索前列醇(Misoprostol以下简称米索)引产出现过强宫缩的对策，为临床干预米索引产的过强宫缩提供理论和实践依据，减少并发症的发生，提高引产分娩的安全性。方法：将2003—05～2004—08我院产科晚期妊娠米索引产出现过强宫缩的80例，随机分为硬膜外阻滞组40例(观察组)，高浓度硫酸镁VD组40例(对照组)，应用美国惠普公司M1351A型胎儿监护仪，观察和比较两组子宫收缩各项指标(间隔时间、持续时间、强度)的变化。结果：硬膜外阻滞对过强宫缩的缓解效果明显优于高浓度硫酸镁VD，应用30min后子宫收缩的各项指标与对照组比较差异有显性。结论：硬膜外阻滞是安全、有效、实用的干预米索引产出现过强宫缩的措施。

Analysis of the Countermeasure of Over Intensity Uterine Contraction Induced by Misoprostol in Late Trimester of Pregnancy

Objective:To explore the countermeasure of over intensity uterine contraction induced by Misoprostol in late trimester of pregnancy, and to provide theoretical and practical basis for interventing over intensity uterine contraction during Misoprostol induced labor, to decrease complications and to increase the reliability of induced labor.Methods:80 cases that produced over intensity uterine contraction induced by Misoprostol in late trimester of pregnancy in our hospital from 2003 May to 2004 August were analyzed, and were randomly divided into peridural anesthesia group(40 cases) and the control group(40 cases). Type M1351A fetus monitor from American Feipu Company was used to observe and compare the index of uterine contraction, including septum, duration, and intensity.Results:The remission effect of peridural anesthesia on over intensity uterine contraction was evidently better than of high concentration MgSO 4 solution. The index of 30 minutes later showed significant difference between peridural anesthesia group and control group.Conclusions:Peridural anesthesia was the safe, effective and practical intervention countermeasures against over intensity uterine contraction induced by Misoprostol.
