How to improve one-time yield in blood plasma separation / 中国输血杂志

ABSTRACT

【Objective】 To analyze the factors affecting "one-time yield" in blood plasma separation (BPS) and explore the methods to improve the rate of it. 【Methods】 The rate of "one-time yield" in BPS of 2018 was calculated and the influencing factors were analyzed. Such influencing factors as air release after leukodepletion, poor performance of leukodepletion filter, selection of blood bag barrel, cup filling method, standing time after centrifugation, separation method were improved in 2019, and the difference of the "one-time plasma yield" rate of fresh frozen plasma/frozen plasma and the centrifugal damage before and after the improvement were compared. 【Results】 After the improvement, the rate of "one-time yield" of fresh frozen and frozen plasma increased to 89% and 80%, respectively, which was significantly increased as compared with that before(P<0.05); the centrifugal damage rate decreased to 0.01%, showed no statistical significance compared with that before. 【Conclusion】 With accurate analysis of the factors affecting "one-time plasma yield", the improved method proved to be effective, the rate of "one-time yield" has been improved significantly, and the blood quality has been guaranteed.
