The amounts of microaggregates of 200 non-selected units of buffycoat-free PRC were determined gravimetrically using a cascade of nylon mesh screen filters with pore sizes of 200, 50, 20 and 10 micrometers. In PRC the total amounts of amorphous debris are on average 2 to 3 times less than in stored whole blood. Nevertheless the quality of the buffycoat-free PRC is subject to immense variation in view of removed debris in individual cases. Microaggregates retained on the 20 and 10 micrometer filter sieves are still considerable, their order of magnitude is comparable to that found on the 200 micrometer sieves, so that a microfiltration is also necessary under 40 micrometers. Taking into account the necessity of eliminating all factors which contribute to the cause or severity of an acute pulmonary failure even buffycoat-free PRC should be transfused through microfilters.
使用孔径为200、50、20和10微米的尼龙网筛级联,通过重量法测定了200个未选择的无白膜血浆置换液单位中的微聚集体数量。在血浆置换液中,无定形碎片的总量平均比储存的全血少2至3倍。然而,鉴于个别情况下去除的碎片,无白膜血浆置换液的质量存在极大差异。保留在20和10微米滤网筛上的微聚集体仍然相当可观,其数量级与在200微米筛上发现的相当,因此在40微米以下也需要进行微滤。考虑到消除所有导致急性肺衰竭病因或严重程度的因素的必要性,即使是无白膜血浆置换液也应通过微滤器进行输注。
