本文讨论妊娠并发症时低纤维蛋白原综合征,纤维蛋白原为凝血过程中不可缺少的凝血因子,其含量正常为0.2—0.4克%。如降低至0.1克,可以发生出血现象。孕妇血浆纤维蛋白原含量,随妊娠各时期而逐渐增高,分娩时略为下降,产后轻度上升,患有某些妊娠并发症时,纤维蛋白原减少,致使血液凝固发生障碍,其机制有两种学说:(一)凝血活素学说:凝血活素由胎盘及蜕膜组织释放,进入母体血循环,加速凝血过程,大量消耗纤维蛋白原,以致血管
This article discusses the complications of pregnancy fibrinogen syndrome, fibrinogen coagulation factor essential for the process of coagulation, its normal content of 0.2-0.4 g%. If reduced to 0.1 grams, bleeding can occur. Plasma fibrinogen levels in pregnant women, with each period of pregnancy and gradually increased, a slight decline during childbirth, mild postpartum increase, with some complications of pregnancy, decreased fibrinogen, resulting in blood coagulation disorders, the mechanism of two Doctrine: (a) thrombospondin theory: thromboplastin released from the placenta and decidua, into the maternal blood circulation, accelerate the process of coagulation, consumption of fibrinogen, resulting in blood vessels
