目的 统计分析茂名市2016—2021年各种成分血临床供血情况,分析不同成分ABO血型供血特点,总结供血趋势,为今后采供血工作提供参考。方法 通过血液信息管理系统和统计“血库库存监控”中血库预警情况,统计分析茂名市2016—2021年各类成分血临床供应情况。结果 2016—2021年茂名市中心血站临床供血总量1 635 494.5 U,年平均增长率10.74%;红细胞类、血浆类、冷沉淀和浓缩血小板临床供应量年平均增长速度分别为11.58%、8.68%、5.88%、19.41%,各血型占比均为O型>A型>B型>AB型;2018年后机采血小板临床供应量逐年增长;AB型浓缩血小板报废占比最大。结论 2016—2021年茂名市中心血站临床血液供应量逐年增长,O型用血在茂名地区所占比例最大,AB型所占比例最小。在未来采供血工作中,结合临床不同血型成分血使用特征,注意不同血型血液库存,优化血库库存警戒线,防止过多血液过期报废。

Objective To statistically analyze the clinical supply of various blood components in Maoming City from 2016—2021, analyze the characteristics of various ABO blood components supply, and summarize the trend of blood supply as a reference for future blood collection. Methods Using the blood information management system and the early warning situation of the blood bank in “blood bank inventory monitoring”, the clinical supply of various blood components from 2016 to 2021 was statistically analyzed. Results The total supply amount of clinical blood from Maoming Central Blood Bank in 2016-2021 was 1635 494.5 U, with an average annual growth of 10.74%; the percentage of each blood components (red cell, plasma, cryoprecipitate and pooled platelets) was O>A>B>AB, with an average annual growth rate of 11.58%, 8.68%, 5.88% and 19.41%.After 2018, the clinical supply of mechanically collected platelets increased year by year.Scrapped pooled platelets of AB type accounted for the largest proportion. Conclusions Clinical blood supply in Maoming central blood bank was increasing yearly from 2016 to 2021, with the largest proportion of blood type O in Maoming region and the smallest proportion of blood type AB.In the future blood collection and supply, we will pay attention to blood products for different blood types in stock by taking into account the different blood types usage,pay attention to the blood stocks of different blood types, optimize the alarm threshold of blood bank stocks, to prevent overmuch blood from expiring and being scrapped.
