摘要 [目的]对两种不同融化新鲜冰冻血浆制备冷沉淀的方法进行比较。[方法]取40袋新鲜冰冻血浆,分别采用4℃冰箱融化离心法和冰冻血浆解冻箱虹吸法制备冷沉淀,并比较其凝血因子Ⅷ(FⅧ)、纤维胶原蛋(Fbg)的含量。[结果]4℃冰箱融化离心法和冰冻血浆解冻箱虹吸法FⅧ每袋含量分别为47.6IU±4.1IU、64.2IU±6.0IU,差异有统计学意义(P<0.01),Fbg每袋的含量分别为88.3mg±3.5mg、92.8mg±4.9mg,差异无统计学意义(P>0.05)。前者新鲜冰冻血浆融化平均所需时间约为8.5h,而后者平均所需的时间仅为1h。[结论]两种方法都能制备出符合GB18469-2001《全血及成分血质量要求》的冷沉淀,但冰冻血浆解冻箱虹吸法能制备高质量的冷沉淀,且简便、快速。
