In a prospective study 383 from 712 women attending our antenatal clinic were found on examination to have pregnancy risks. These were followed with regard to the time of first occurrence, duration and time of last occurrence, as well as their relation to other risk factors occurring in both history, examination or during labour. The method of delivery, necessity for postpartal intensive pediatric care and the perinatal mortality were considered. Risks included antepartal haemorrhage in the first trimester (median time of onset 11 weeks); in the second trimester: hypotension (20 weeks), cervical incompetence (21 weeks), anaemia (25,5 weeks), premature labour (29 weeks) and uterus size inappropriate to gestational age (34,5 weeks) in the third trimester. Antepartal haemorrhage tends to be episodic (median duration of bleeding one week). The average duration for a cerclage was 16 weeks. The other risk factors were observed to last between 3 and 8 weeks. The onset and duration of risk factors found on examination considered alone do not present a sufficient criterion to enable their gravidity to be judged.
在一项前瞻性研究中，对前来我们产前诊所就诊的712名女性进行检查后发现，其中383人存在妊娠风险。对这些风险进行了跟踪，记录首次出现的时间、持续时间和最后一次出现的时间，以及它们与病史、检查或分娩期间出现的其他风险因素的关系。考虑了分娩方式、产后新生儿重症监护的必要性和围产期死亡率。风险包括孕早期的产前出血（发病中位时间为11周）；孕中期的低血压（20周）、宫颈机能不全（21周）、贫血（25.5周）、早产（29周）以及孕晚期子宫大小与孕周不符（34.5周）。产前出血往往呈间歇性（出血中位持续时间为1周）。宫颈环扎术的平均持续时间为16周。观察到其他风险因素持续3至8周。仅考虑检查中发现的风险因素的发病时间和持续时间，不足以作为判断其妊娠严重程度的充分标准。
