ABSTRACT
【Objective】 To investigate the safety of regular plasma donors aged 55 to 60, so as to provide reference for retention and recruitment of elderly plasma donors in China. 【Methods】 Plasma donors from 9 blood products manufacturing enterprises from 2018 to 2020 and the local general population were selected as the research objects. The total protein level, albumin and globulin ratio(ALB/GLB, A/G) and adverse reactions of plasma donation of regular plasma donors and local general population were retrospectively analyzed. 【Results】 The total protein level (g/L) and A/G of plasma donors aged 56 to 60 and the general population were 61.21±5.62 vs 60.04±6.93 and 1.610±0.299 vs 1.635±0.330, respectively, and the differences were statistically significant. The total protein level of regular plasma donors was higher than that of general population, but A/G was slightly lower than that of general population. From 2018 to 2020, there were a total of 23 056 302 plasma donations in 108 plasma stations, and adverse reactions occurred in 20 932 donations, with a total incidence of 0.09%, with no serious adverse reactions. 【Conclusion】 It is safe for regular plasma donors aged 55 to 60 to donate plasma, and the retention of them can alleviate the pressure of plasma supply.
ABSTRACT
【Objective】 To explore the characteristics and influencing factors of adverse reactions of apheresis plasma donation in 27 domestic plasma donation stations, and put forward targeted preventive measures. 【Methods】 A total of 6 275 plasma donors with adverse reactions from 2018 to 2020 in 27 plasma donation stations in China were selected as the research objects. The types of adverse reactions, ages, time of plasma donation and other related characteristics were counted and retrospectively analyzed. 【Results】 From January 2018 to December 2020, the incidence of adverse reactions of apheresis plasma donation in 27 plasma collection stations was 1.37‰, including vasovagal reaction/hypovolemia (3 208 cases, 0.700‰), sodium citrate allergy/hypocalcemia (1 205 cases, 0.263‰), hypoglycemia (1 020 cases, 0.223‰), syncope (796 cases, 0.174‰), hematoma (8 cases, 0.002‰), other reactions (36 cases, 0.008‰), all of which were non-severe adverse reactions. There were significant differences in the incidence of different types of adverse reactions (P0.05). 【Conclusion】 The incidence of adverse reactions in plasma donation is low in China. In the process of plasma donation, attention should be paid to first-time and young (18-25 years old) donors. The incidence of adverse reactions in 56-60 years old donors is the lowest, which can provide data support for the age revision of plasma donors in China.
