弥漫性血管内凝血(DIC)系指在某些致病因素作用下,促凝物质进入血流,引起毛细血管、小静脉、小动脉内广泛的纤维蛋白沉积和血小板凝聚,形成弥散的微血栓。它可给机体带来不良的后果:1.微循环内发生闭塞性血栓栓塞,导致细胞破坏死亡和多脏器功能障碍,以致衰竭;2.消耗大量凝血因子和血小板,并使体内纤维蛋白溶解系统活化,形成纤维蛋白裂解产物,造成血液凝固障碍和低凝状态,而渗血不止;3.释放大量血管活性物质加重微循环的淤滞和血浆渗
Diffuse intravascular coagulation (DIC) refers to the role of certain causative factors, procoagulant into the bloodstream, causing capillary, venules, small arteries extensive fibrin deposition and platelet aggregation, the formation of diffuse microthrombi . It can bring adverse consequences to the body: 1. occlusive thromboembolism occurs within the microcirculation, leading to cell destruction and multiple organ dysfunction, resulting in failure; 2. Consumption of large amounts of coagulation factors and platelets, and the body fibrinolysis System activation, the formation of fibrin cleavage products, resulting in blood coagulation disorders and low coagulation state, and bleeding more than 3. Release of a large number of vasoactive substances increase microcirculation stasis and plasma permeability
