Routine preparation of red cell concentrates in our institute removes 90% of platelets and 70% of leucocytes in whole blood. Microaggregate formation in whole blood and red cell concentrates was comparatively evaluated by blood passage through a membrane filter with a pore size of 12 micron. Dry weight residues on the filter due to microaggregates were 5 to 10 times lower in red cell concentrates as compared to whole blood at any point of a 20 day storage period. In addition, the decrease in flow rate with increasing storage time was much more marked for whole blood than for red cell concentrates.
我院制备红细胞浓缩液的常规方法可去除全血中90%的血小板和70%的白细胞。通过孔径为12微米的膜滤器过滤血液，对全血和红细胞浓缩液中的微聚集体形成情况进行了比较评估。在20天储存期的任何时间点，红细胞浓缩液中因微聚集体导致的滤器干重残留量比全血低5至10倍。此外，全血随储存时间延长的流速下降比红细胞浓缩液更为明显。
