孕龄对未足月胎膜早破围生儿及分娩方式的影响

目的：探讨孕龄对未足月胎膜早破围生儿及分娩方式的影响。方法：选择本院2007年1月～2010年12月住院的86例未足月胎膜早破患者进行回顾性分析,按发病孕龄分为两组：A组32例,发病孕龄28～34＋6周;B组54例,发病孕龄35～36＋6周。比较不同孕周对围生儿及分娩方式的选择的影响。结果：两组围生儿胎儿窘迫率分别为45.7%、31.5%,新生儿窒息率分别为51.4%、35.2%,肺部并发症及感染率分别为57.1%、31.5%,围生儿死亡率分别为22.9%、5.6%。差异有统计学意义（P〈0.05）。两组的分娩方式比较,阴道分娩和剖宫产比较差异无统计学意义（P〉0.05）。结论：对于孕周为28~34＋6周胎膜早破的孕妇宜采用期待疗法,尽可能延长孕周,同时给予促胎儿肺成熟、预防感染治疗,以减少新生儿并发症的发生,降低新生儿死亡率。

The impact of the gestational age on the premature rupture of membranes of preterm perinatal child and the delivery mode

Objective： To investigate the impact of the gestational age on the premature rupture of membranes of preterm perinatal child and the delivery mode. Methods： Chose 86 cases of hospitalized patients with preterm premature rupture of membranes from January 2007 to December 2010 in our hospital for retrospective analysis, on the basis of the incidence of gestational age divided into two groups, group A of 32 cases, the incidence of gestational age was 28-34＋6 weeks; group B of 54 cases, the incidence of gestational age was 35-36＋6 weeks. Compared the effects of different gestational age on the perinatal child and the choice of the delivery mode. Results： The rate of the fetal distress of two groups respectively was 45.7%, 31.5%, the neonatal respectively was 51.4%, 35.2%, the pulmonary complications and infection respectively was 57.1%, 31.5%, the mortality rate respectively was 22.9%, 5.6%. Difference was statistical significance （P〈0.05）. Compared the delivery mode of two groups, there was no statistical significance between the vaginal delivery and the cesarean section （P〉0.05）. Conclusion： Choose expect therapy for the premature rupture of membranes pregnant women in the gestational age of 28-34＋6 weeks, extend the gestational age as long as possible, while giving to promote fetal lung maturation, prevent the infection treatment to reduce the incidence of neonatal complications and reduce the neonatal mortality.
