冷沉淀制备时间对凝血因子和纤维蛋白原含量的影响

Influence of preparation time of cryoprecipitate on the contents of coagulation factors and fibrinogen

目的：分析冷沉淀制备时间对凝血因子和纤维蛋白原含量的影响。方法选取2013年9月至2013年12月采集的93份新鲜冰冻血浆，均分为3组（各31份），分别于6h、8h、10h再将各组新鲜血浆制备成冷沉淀。对3组冷沉淀中纤维蛋白原及凝血Ⅷ因子含量进行测定并进行对比分析。结果制备时间分别为6h、8h、10h的3组冷沉淀中凝血因子和纤维蛋白原含量比较，差异均无统计学意义（P＞0.05）。结论全血采集后10h内不同时间点制备冷沉淀对其凝血因子和纤维蛋白原含量无较大影响。

Objective To analyze the influence of preparation time of cryoprecipitate on the contents of coagulation factors and fibrinogen. Methods 93 samples of fresh frozen plasma collected from September of 2013 to December of 2012 were selected and divided into 3 groups, 31 samples in each group. The fresh frozen plasma in 3 groups were prepared cryoprecipitate at the 6th, 8th, 10th hours respectively. The contents of coagulation factors and fibrinogen in 3 groups were detected and compared. Results The contents of coagulation factors and fibrinogen in 3 groups had no statistical difference (P>0.05). Conclusion The preparation time of cryoprecipitate within 10 hours after collecting the fresh frozen plasma had no influence on the contents of coagulation factors and fibrinogen.
