目的:观察机采血小板在采集及运输过程中的活性变化。方法:对134单位机采血小板在采集及运输过程中的有关参数进行记录,观察输注后的临床疗效。结果:当在采集、运输过程中不能保证血小板在振荡条件下保存时,会导致血小板绝对值降低;乳酸值增加;聚集率下降。结论:机采血小板在采集、运输中必须在振荡条件下保存,否责会影响其活性。
Objective: To observe the change of activity of platelet collecting and transporting in the process of collecting and transporting. Methods: The relevant parameters of 134 unit platelets collected and transported were recorded, and the clinical effect after infusion was observed. Results: When the platelets were not preserved under shaking conditions during collection and transportation, the platelet absolute value decreased, the lactate value increased, and the aggregation rate decreased. Conclusion: The platelets collected and transported must be preserved under shaking conditions, which will affect their activity.
