In the presented material the frequency of postpartum haemorrhage is 0.74%. In the study sixty-nine histologically confirmed cases were considered. At histological examination three main factors were found--subinvolution of the placental site, retained placental tissue, and inflammation, each of them responsible for about one third of all cases. The possible influence of such factors as parity, time of delivery, frequency of caesarian section, frequency of intrauterine exploration, manual extraction of the placenta, and induction and stimulation of the delivery on late postpartum haemorrhage is discussed.
在呈现的资料中，产后出血的发生率为0.74%。该研究纳入了69例经组织学确诊的病例。组织学检查发现三个主要因素——胎盘附着部位复旧不全、胎盘组织残留和炎症，每一个因素约占所有病例的三分之一。文中还讨论了诸如产次、分娩时间、剖宫产频率、宫腔探查频率、人工剥离胎盘以及引产和催产等因素对晚期产后出血的可能影响。
