【摘要】 目的 探讨2014—2020年血液成分制备技术的应用现状。方法 选取2014—2020年我国采供血机构执业比对平台血液中心16家，分析其具有旁路系统的血袋耗材、去除白细胞、血液辐照和血浆成分病原体灭活技术的应用情况。结果 16家血液中心中，11家（68.75%）采集全血使用旁路系统分流前端血液。14家（87.50%）开展红细胞成分血储存前去除白细胞，其中去白细胞悬浮红细胞的质控抽检结果显示，200 ml规格白细胞残留量平均值为（0.18～0.42）×106/袋，300 ml规格的平均值为（0.22～0.33）×10~6/袋，400 ml规格的平均值为（0.78～0.86）×106/袋。16家（100.00%）单采血小板均去除白细胞。12家（75.00%）进行红细胞成分血和血小板成分血发放前辐照，辐照技术使用率呈现较大差异。11家（68.75%）血浆成分血进行病原体灭活处理。结论 具有旁路系统的血袋分流前端血液、去除白细胞、辐照和病原体灭活等血液成分制备技术的使用率在不同血液中心呈现较大差异，应用血液成分制备技术预防输血传染病的空间有待进一步提升。更多还原

【Abstract】 Objective To explore the application status of blood component preparation techniques. Methods A total of 16 blood centers of blood collection and supply institutions from 2014 to 2020 were selected, the application of blood bag consumables with bypass system, leukocyte removal technology, blood irradiation and plasma component pathogen inactivation technology were analyzed. Results Diversion pouch was applied in 11(68.75%) blood centers while collecting whole blood. Leukocyte reduction of red cells before storage was applied in 14(87.50%) blood centers. The leukocyte residue of red blood cells in additive solution leukocyte reduced were(0.18 ～ 0.42) × 106/bag in 200 ml,(0.22 ～ 0.33) × 106/bag in300 ml,(0.78 ～ 0.86) × 106/bag in 400 ml. Leukocyte reduction of apheresis platelet was applied in 16 blood centers.Irradiation of red cells and platelets prior to issue was applied in 12(75.00%) blood centers, but there was great difference in the use rate of irradiation among the above blood centers. Pathogen inactivation of plasma was applied in 11(68.75%) blood centers. Conclusions The preparation capability of blood components is different in different blood centers, such as using diversion pouch, leukocyte reduction, irradiation and pathogen inactivation. We should do more to improve blood component preparation techniques to reduce the residual risk of transfusion.更多还原
