目的：描述分娩终止妊娠的阴道出血和相关疼痛。设计：描述性研究的基础上获得的信息，在怀孕期间进行问卷调查。地点：丹麦奥胡斯大学医院产科的产科护理诊所。受试者：妇女（n = 8714）与单胎妊娠参加常规产前保健部门在1989年至1991年的2年期间。在怀孕期间进行了三次问卷调查，5868名（67%）妇女完成了所有问卷。主要测量指标：出血的特征为频率、首次发生时的胎龄、持续时间和量。还描述了与腹痛和住院相关的出血。结果：出血的总频率为19%（n = 1091）。首次发病的中位孕周为8周。出血的中位持续时间为2天，中位发作次数为1次。研究发现出血量与出血持续时间之间存在相关性，三分之二的女性没有与出血相关的腹痛。有疼痛的女性比没有疼痛的女性出血更严重，流血的时间更长。出血导致五分之一的妇女住院治疗。尤其是妊娠中期出血、出血量大、持续时间长和伴有疼痛的妇女住院治疗。结论：通过使用自填式问卷，发现出血频率高于先前的研究，其中信息基于医疗记录。因此，必须仔细考虑和描述妊娠和出血相关妊娠并发症研究的信息来源。
Objective: To describe vaginal bleeding and associated pain in pregnancies terminated by childbirth. Design: A descriptive study based on information obtained by questionnaires administered during pregnancy. Setting: Antenatal care clinic at the Obstetrical Department, Aarhus University Hospital, Denmark. Subjects: Women (n = 8714) with singleton pregnancies attending routine antenatal care at the Department during a 2-year period from 1989 to 1991. Three questionnaires were administered during pregnancy and 5868 (67%) women completed all questionnaires. Main measures: Bleeding was characterized by frequency, gestational age at first occurrence, duration, and amount. Hemorrhage associated with abdominal pain and hospitalization was also described. Results: The overall frequency of bleeding was 19% (n = 1091). The median week of first occurrence was 8 gestational weeks. The median duration of bleeding was 2 days, and the median number of episodes was one. An association between the amount and duration of bleeding was found. Two thirds of the women had no abdominal pain associated with bleeding. Women with pain experienced heavier bleeding and bled for more days than women without pain. Bleeding resulted in hospitalization in one out of five women. In particular, women with second trimester bleeding, with heavy bleeding, long duration, and associated pain were hospitalized. Conclusion: By the use of self-administered questionnaires a higher frequency of bleeding was found than in previous studies in which information has been based on medical records. Thus, the source of information in studies of pregnancy and bleeding-associated pregnancy complications must be carefully considered and described.
