目的分析48 h内冰冻机采血小板复融出现絮状物凝块效果分析。方法使用Amicus和Mcs+血细胞分离机采集血小板,分析了460 U冰冻机采血小板复融过程中出现絮状物凝块效果分析。结果冰冻机采血小板的复融过程出现絮状物凝占2.6%。结论制备高质量的冰冻机采血小板,冰冻机采血小板时间的选择很重要,血源的筛选是基础,注射DMSO的技巧是关键。 Objective To analyze the effect of flocculent clot formation in platelet reabsorption in a cryogenic machine within 48 h. Methods Platelets were collected using Amicus and Mcs + hemocytometer, and the flocculent clotting effect was analyzed during the 460 U cryoablation. Results Frozen platelet aggregation occurred in the process of flocculation 2.6%. Conclusion The preparation of high quality ice machine platelets, ice machine platelet selection time is important, the screening of blood is the basis, the injection of DMSO skills is the key.
