妊娠晚期羊水过多57例临床分析

The clinical analysis of 57 polyhydramnios in the last trimester.

目的 探讨妊娠晚期羊水过多的妊娠结局及无激惹试验的临床应用价值。方法 对妊娠晚期羊水过多孕妇 5 7例进行回顾性分析和总结 ,以比较羊水过多的发生时间、性质、程度与胎儿畸形的相关性 ,及无激惹试验正常和异常与围生儿预后的关系。结果 羊水过多发生在妊娠中晚期 (2 9～ 36 + 6周 )胎儿畸形发生率明显高于妊娠足月 (37～ 42周 ,P <0 0 5 ) ;急性或重度羊水过多和无激惹试验异常的胎儿窘迫、新生儿窒息及胎儿畸形发生率明显高于慢性或轻中度羊水过多和无激惹试验正常的孕妇 (P <0 0 5 )。结论 妊娠晚期羊水过多的妊娠结局与其发生时间、性质、程度有密切的相关性 ;无激惹试验在其预测围生儿预后具有较好的临床价值。

Objective To study the pregnancy outcome and the clinical value of NST in polyhydramnios in the last trimester.Methods We retrospectively analysed 57 cases of polyhydramnios in the last trimester in our hospital.The relationship between the time of onset,quality,degree of polyhydramnios and fetal congenital abnomalities,and that between the results of NST and perinatal prognosis were all studied.Results The rate of fetal congenital abnormalities in 29～36 +6 gestational weeks was higher than that in full-term(P<0 05).The rate of fetal distress,neonatal asphyxia and fetal congenital abnomalities in acute or severe cases and abnormal NST were higher than those in chronic or mild and moderate cases and normal NST(P<0 05).Conclusion There is close relationship between pregnancy outcome of polyhydramnios in the last trimester and its time of onset,quality and degree.Non-stress test has a higher clinical value in foretelling perinatal prognosis of polyhydramnios.
