EARLY SYMPTOMS OF PRETERM LABOR AND PREMATURE RUPTURE OF MEMBRANES

这项研究将试图界定早产的症状 (PTL)和胎膜早破（PROM），以更好地 在PTL或PROM发作之前诊断和治疗这些症状。 将检验两个假设。 1)女人也会经历同样的事情 无论最终结果是PTL还是PROM。 （二） 后倾“高危”妇女产前表现出不同的 比那些长期怀孕的症状。

This study will attempt to define the symptoms of preterm labor (PTL) and premature rupture of membranes (PROM) in order to better diagnose and treat these symptoms prior to onset of PTL or PROM. Two hypotheses will be tested. 1) Women experience the same symptoms whether the eventual outcome is PTL or PROM. (2) Retrospectively "high risk" women present prenatally with different symptoms than those term pregnancy.
