弥漫性血管内凝血(DIC)是一个病理过程,在临床上由于某些致病因素的影响,在微循环内发生广泛的纤维蛋白原沉积和血小板凝聚,因此引起一系列病理生理变化。妊娠晚期血液处于高凝状态,凝血栓子不断形成,不仅消耗大量凝血物质而导致消耗性的低凝性出血,也会造成组织器官的栓塞或衰竭,如不及时诊断、治疗,病情有可能急剧恶化甚至死亡。在产科,妊娠高血压综合征、前置胎盘、 Diffuse intravascular coagulation (DIC) is a pathological process, clinically due to some of the risk factors, the occurrence of extensive fibrin deposition within the microcirculation and platelet aggregation, thus causing a series of pathophysiological changes. In the third trimester of pregnancy, the blood is hypercoagulable and coagulation emboli continue to form, which not only consumes a large amount of coagulation substances and causes consumptive low condensable bleeding, but also causes embolization or failure of tissues and organs. If not timely diagnosis and treatment, the condition may be abrupt Worsen or even die. In obstetrics, pregnancy-induced hypertension syndrome, placenta previa,
