-
摘要: 目的 比较顶底袋与四联袋白膜法制备浓缩血小板的质量差异。 方法 采集40个400 mL ACD抗凝全血,摇匀后静置1 h, 均分至顶底袋和四联袋中,每袋200 mL。以顶底袋为实验组,四联袋为对照组,应用G5血细胞分离机制备浓缩血小板。 结果 实验组中血小板为(986.0±277.0)×109/L, 对照组中血小板为(705.0±322.0)×109/L, 差异有统计学意义(P<0.01)。2组血浆含量以及血浆中残留红细胞、血小板、白细胞及血红蛋白含量比较,差异均无统计学意义(P>0.05)。 结论 顶底袋制备浓缩血小板数量与质量以及红细胞回收率均优于四联袋。Abstract: Objective To compare the difference of quality of concentrated platelet prepared by white film with two methods of blood bag. Methods Totally 40 pieces of 400 mL ACD anticoagulant whole blood were collected and shaken well. After setting for 1 hour, the blood samples were evenly divided into top-bottom blood bag and quadruplet blood bag, with 200 mL whole blood in each bag. The top-bottom blood bag was selected as experimental group, and the quadruplet blood bag was selected as control group. Platelet concentrate was purified by the G5 Automatic Blood Component Processing System. Results The platelets were(986.0±277.0)×109/L in the experimental group and(705.0±322.0)×109/L in the control group, and there was significant difference between two groups(P<0.01). There were no significant differences in the content of plasma and the contents of residual red blood cells, platelets, white blood cells and hemoglobin in plasma between two groups(P>0.05). Conclusion The quantity and quality of platelet concentrate as well as the reclamation rate of red blood cells prepared by the top-bottom blood bag are better than those by the quadruplet blood bags.
