【摘要】 目的 研究我国省级血液中心疫情前后血小板成分血生产量、单采血小板采集量和浓缩血小板制备量的变化趋势。方法 收集19家省级血液中心2016—2021年与单采血小板采集量及浓缩血小板制备量相关的数据，分别计算疫情发生之前4年(2016—2019年)及新冠疫情期间(2020年和2021年)血小板成分血的生产量、单采血小板采集量和浓缩血小板制备量，分析其变化趋势。结果 2016—2019年19家血液中心血小板成分血生产总量稳步增长，2020年降低4.16%,2021年增加15.60%,超过疫情前水平。2020年42.11%(8/19)的血液中心血小板成分血的生产量较上一年有所降低，2021年94.74%(18/19)的血液中心血小板成分血的生产量较上一年有所增加。单采血小板采集量变化趋势同血小板成分血生产量趋势基本一致。2017、2018年浓缩血小板制备总量较前一年均翻番；2019年浓缩血小板制备总量较前一年减少了67.98%;2020年增加30.38%,2021下降27.08%。结论 新冠疫情前血小板成分血生产总量稳步增长。受疫情影响，2020年生产总量减少，部分血液中心受到较大冲击。2021年，随着我国防控措施优化，在政府的大力支持和各采供血机构采取的各种有力措施下，血小板成分血的生产总量增加。更多还原

【Abstract】 Objective To study the changes of platelet components(PC), apheresis platelets(AP) and pooled platelet concentrates(PPC) production of 19 provincial blood centers before and during the COVID-19 epidemic. Methods The data related to the collection of AP and the preparation of PPC from 2016 to 2021 of 19 provincial blood centers was collected. The production of PC, AP and PPC during the four years before the epidemic(i.e. 2016-2019) and during the COVID-19 epidemic(i.e. 2020 and 2021) were calculated respectively, and the change of production was analyzed. Results The total production of PC in 19 blood centers steadily increased from 2016 to 2019, with a decrease of 4.16% in 2020 and an increase of 15.60% in 2021, exceeding the output before the COVID-19 epidemic. In 2020, the production of PC of 42.11%(8/19) blood centers decreased compared with 2019, while 94.74%(18/19) in 2021 increased compared with 2020. The changes of AP output was basically consistent with the trend of PC. The total production of PPC in 2017 and 2018 both doubled compared to the previous year, while decreased by 67.98% in 2019, increased by 30.38% in 2020 and decreased by 27.08% in 2021. Conclusion The total production of PC kept increasing steadily between 2016 and 2019, but decreased in 2020 under the COVID-19 epidemic, with some blood centers being significantly affected. In 2021, with the strong support from government and various measures by blood centers, the total production of PC increased.更多还原
