After the fetus’s birth the adequate contraction of the uterus as well as the local blood coagulation in the arteries (thrombus creation) is responsible for the bleeding diminution. Considering the significant blood flow of the uterus during the pregnancy and the great area of the lesion, it is comprehensible that in case of complications of these mechanisms grave bleeding may occur (haemorrhagia postpartum) which can endanger the mother’s life. The bleedings after delivery may occur due to scaling or retention anomalies of the placenta, inadequate contraction of the uterus, lesion of the uterine canal and thrombotic disturbance. If the postpartum bleeding is laid during delivery and in the next 24 hours then we speak about primaer (early) postpartum bleeding; if the postpartum bleeding is laid after the first 24 hours but during the 6 weeks postpartum there is a secundaer (late) postpartum bleeding. Postpartum bleedings can be observed at 5% of total deliveries where 80% are early and 20% are late postpartum bleedings. In our study we attempted to identify the predisposing factors by investigating the causes of postpartum bleedings. If these factors exist, there is a major chance of postpartum bleeding. It is essential to know these predisposing factors regarding the treatment, because with their early recognition we can take measures of precautions and most postpartum bleedings can be prevented.
