献血者血小板数量及血容量对机采血小板采集量的影响

摘要

目的：分析献血员血小板数量及处理血量对机采血小板采集量的影响。方法应用Trima血细胞分离机采集100名献血者的双份血小板。结果通过多元回归分析发现，献血者采前的血小板计数（Plt）和血容量（BV）与血小板采集量之间存在回归关系，其标准偏回归系数β值分别为-0.370和-0.201，P＜0.01。结论对采前的Plt和BV水平较低的献血者，可采用Trima血细胞分离机进行采集。%Objective To analyze the influence on apheresis platelets collection quantity of platelets count (Plt) and blood volume (BV) of donors. Methods Double platelets were collected from 100 donors using the Trima blood separator. Results By multivariate linear regression analysis, it was found that there were regression relationships between donors' Plt and BV before donation and platelets collection quantity (β=-0.370 and-0.201, P<0.01). Conclusion For donors with low level Plt or BV, Trima blood separator can be used.
