背景 为了减少制备单一供者的血小板(SDP)的费用,作者设计一项研究以调查在单采血小板过程中收集的血浆副产品是否符合FFP的质量要求,而且不降低SDP成分的质量。研究设计和方法 采用全自动细胞分离仪,对92名血小板计数每升小于270×10~9的供者进行血小板单采。编程单采机以在收集中含有3×10~(11)PLT的250ml血浆,再另外收集350ml血浆,或者在10个程序中编辑收集含有3×10~(11)PLT的250ml血浆,但不再另外收集血浆制品。对血浆中的FⅤ和FⅧ以及残留的RBC、
Background To reduce the cost of preparing a single donor platelet (SDP), the authors devised a study to investigate if the plasma byproduct collected during apheresis meets the quality requirements of FFP without compromising the quality of the SDP component. Study Design and Methods Platelet apheresis was performed on 92 platelet donors with a platelet count of less than 270 × 10 ~ 9 using a fully automated cell separator. A single-machine was programmed to collect 250 ml of plasma containing 3 x 10-11 PLTs in the collection and an additional 350 ml of plasma or 250 ml of plasma containing 3 x 10-11 PLTs in 10 programs but not Another collection of plasma products. For plasma FV and FⅧ and residual RBC,
