曾称为冷沉淀,是新鲜冰冻血浆在1℃~6℃融化后分离大部分血浆,剩余的血浆与冷不溶物在1小时内快速冰冻呈固态,是新鲜冰冻血浆中大部分凝血因子的浓缩制品,主要有效成分有FⅧ、血管性血友病因子(v WF)、纤维蛋白原和纤维结合蛋白等。主要适应证有:1.血友病A及获得性FⅧ缺乏症。2.血管性血友病。3.先天性和获得性纤维蛋白原缺乏症。4.大出血、DIC等快速补充纤维蛋白原。5.创面、溃疡面局部使用促进愈合。 Once known as cryoprecipitate, fresh frozen plasma melts at 1 ° C to 6 ° C and separates most of the plasma. The remaining plasma and cold insolubles rapidly solidify in 1 hour, which is the concentration of most of the clotting factors in fresh frozen plasma Products, the main active ingredient F Ⅷ, von Willebrand factor (v WF), fibrinogen and fiber-binding protein. The main indications are: 1. Hemophilia A and acquired FⅧ deficiency. 2. Vascular hemophilia. 3. Congenital and acquired fibrinogen deficiency. 4. Bleeding, DIC and other rapid replenishment of fibrinogen. 5 wounds, ulcers and local use to promote healing.
