早发型重度子痫前期86例治疗分析

Treatment analysis of 86 cases of early-onset severe preeclampsia

目的探讨早发型重度子痫前期最佳终止妊娠的时间及方式。方法回顾分析2005-01～2011-12该院收治的86例早发型重度子痫前期病例的临床资料,比较不同孕周严重并发症发生情况和妊娠结局。结果孕周低于30周的新生儿存活率低,但母体并发症发生概率低。孕30～34周者新生儿存活率高于其他孕周,且随孕周增加新生儿患病率降低。延长孕周在14d内母体并发症概率无明显增加。结论早发型重度子痫前期最佳终止妊娠时间为34周左右。估计胎儿存活可能性小者,应以阴道分娩为主。

Objective To explore the best time and mode of termination of pregnancy for early-onset severe preeclampsia. Methods The clinical data of 86 cases of early-onset severe preeclampsia treated from January 2005 to December 2011 were retrospectively analysed. The complications and pregnancy outcome in different weeks of preg- nancy were compared. Results The survival rate of newborn whose week of pregnancy less than 30 weeks was low, but complications rate of the mater was low;the survival rate of newborn whose weeks of pregnancy between 30 and 34 was higher than other pregnant weeks, prevalence rate was lower with the increase of the gestational weeks of new- born. The complications rate of mater did not increase obviously with weeks of pregnancy extended less than 14 days. Conclusion The best time of termination of pregnancy for early-onset severe preeclampsia is about 34 weeks. The fetus whose survival possibility is small, should choose vaginal delivery mainly.
