283 patients with vaginal bleedings in the first three months of pregnancy were included in an analysis and compared to a control group. We could not find a correlation between bleeding in the early weeks of pregnancy and the age of the mother, the onset of menarche, parity, and preceded premature deliveries. On the other hand we found a significantly high number of bleedings in women, who already had abortions before, and diseases during pregnancy (infections, hyperemesis gravidarum). No statistical differences could be discovered in relation to the control group referring to the course of labour (rupture of membranes, changes of the amniotic fluid, operative deliveries, obstetrical presentation, first and second stage of labour, and complications of the delivery). The average birth weight was significantly lowered because of the large amount of premature births. We could not prove any increase of the rate of deformity after bleeding in the early weeks of pregnancy.
283例妊娠前三个月出现阴道出血的患者被纳入一项分析，并与一个对照组进行比较。我们未发现妊娠早期出血与母亲年龄、初潮年龄、产次及既往早产之间存在相关性。另一方面，我们发现既往有过流产史以及孕期患有疾病（感染、妊娠剧吐）的女性出现出血的数量显著偏高。在分娩过程（胎膜破裂、羊水变化、手术分娩、胎位、第一和第二产程以及分娩并发症）方面，与对照组相比未发现统计学差异。由于大量早产，平均出生体重显著降低。我们未能证实妊娠早期出血后畸形率有任何增加。
