正常人体内有凝血和抗凝血系统,两者处于动态平衡,故血管内的血液不会凝固。在某些致病因素影响下,常可使血管内皮受损,或因释放组织凝血活酶或其他凝血成份,从而促进体内凝血过程,使微循环内发生血小板聚集和纤维旦白沉着,形成血栓,称弥漫性血管内凝血。常见于下列情况: 1.各种严重感染性疾患:败血症、中毒 Normal human coagulation and anticoagulant system, both in a dynamic balance, so the blood vessels will not coagulate blood. Under the influence of certain pathogenic factors, can often make the vascular endothelial damage, or due to the release of tissue thromboplastin or other coagulation components, thereby promoting the process of coagulation in vivo, so that microcirculation platelet aggregation and fibrin deposition, the formation of thrombus , Said diffuse intravascular coagulation. Common in the following situations: 1. A variety of serious infectious diseases: sepsis, poisoning
