目的 通过回顾分析广州地区Rh阴性血的采供情况,了解Rh阴性红细胞的供应特点,更好地实施Rh阴性血液库存管理,保障输血安全。方法 统计2011—2017年广州血液中心Rh阴性血液采集量与供应量,血型及医院供血量的分布情况。结果 2011—2017年广州血液中心Rh阴性全血采集量为11 283 U,占总采血量的0.39%(11 283/2 902 485),供应总量为11 693 U,占红细胞类成分血总供应量的0.43%(11 693/2 762 229),其中悬浮红细胞供应比例逐年增加,冰冻解冻去甘油红细胞供应比例逐年下降,并从2014年起Rh阴性悬浮红细胞供应增长率明显高于血液采集增长率;4种血型供应量总体比较,差异有统计学意义(F=22.217,P＜0.05),A、B型Rh阴性悬浮红细胞供应增长最快,增长率分别为137.3%和134.1%,医院分布以三级以上及综合医院为主。结论 应根据广州地区Rh阴性红细胞采供特点,来持续改进Rh阴性血源招募和采供策略。通过建立一支Rh阴性定期献血者队伍,加强Rh阴性血液统筹管理和临床科室-输血科-采供血机构的沟通,促进Rh阴性血液的供需平衡,保障Rh阴性患者输血安全。

Objective To understand the characteristics of Rh-negative red blood cells (RBC) supply, improve the management of storage and guarantee the safety of blood transfusion. The collection and supply of Rh-negative RBC in Guangzhou city was retrospectively analyzed. Methods The amount of Rh-negative RBC collection and supply, the distribution of ABO blood type and the consumption of blood by different hospitals in Guangzhou Blood Center from 2011 to 2017 were statistically analyzed. Results During 2011-2017, 11 283 U Rh-negative RBC was collected in Guangzhou Blood Center, accounting for 0.39% of total RBC collection (11 283/2 902 485); 1 693 U Rh-negative RBC was supplied, accounting for 0.43% of the total blood supply (11 693/2 762 229). The proportion of suspended RBC supply increased year by year, in contrast with the decease of proportion of frozen defrosteddeglyceal RBC supply. In addition, the growth rate of Rh-negative suspended RBC supply was higher than that of RBC collection since 2014 (F=217, P<0.05). A-and B-Rh negative suspended RBC supply increased, with growth rates of 137.3% and 134.1%, respectively. The Rh negative RBC was predominantly supplied to Grade III and general hospitals. Conclusion By establishing a team of Rh-negative regular blood donors, the strategies for recruitment, collection and supply of Rh-negative RBC should be continuously improved according to the characteristics of Rh-negative RBC collection and supply in Guangzhou. The coordinating management of Rh-negative, as well as the communication of clinical departments, departments of transfusion and blood banks should be improved. In addition, the balance between supply and demand of Rh-negative blood should be promoted, and the safety of blood transfusion for Rh-negative patients can be improved.

目的 分析抽检血液成分关键指标结果并采用趋势分析方法进行评估。方法 收集整理2015—2017年每月1次的8种血液成分质量控制的检测数据,选择关键指标并制作折线图,联合行动限和警戒限进行趋势分析。结果 未能100%达到GB 18469—2012《全血及成分血质量要求》的项目包括悬浮红细胞容量及Hct、单采血小板及浓缩血小板血小板含量、新鲜冰冻血浆及冷沉淀VIII因子含量。新鲜冰冻血浆及冷沉淀的VIII因子含量项目分别出现10次和5次偏离数据;单采血小板及浓缩血小板的血小板含量项目分别出现3次和4次偏离数据。结论 根据血液成分的关键指标结果进行趋势分析发现问题,主动寻找原因并及时采取相应措施,是确保血液质量的一种有效手段。

Objective To analyze and evaluate the results of key indexes of the blood component by trend analysis. Methods Collected and arranged the data of eight kinds of blood component quality control,which was did once month in 2015-2017.Selected the key indexes and made the line charts.Allied with the action limits and warning limits for trend analysis. Results The key indexes could not 100% meet the “Quality requirements for whole blood and component blood”,including capacity and Hct of suspended red blood cell,platelet content of apheresis platelets and platelets concentrate,factor VIII content of fresh frozen plasma and cryoprecipitate.The factor VIII of fresh frozen plasma and cryoprecipitate showed ten and five deviation data, respectively, the platelet content of apheresis platelet and platelets concentrate showed three and four deviations, respectively. Conclusion It's an effective way to ensure blood quality by trend analysis based on the results of key indexes of blood components, and actively find the cause and take corresponding measures in time.
