The filtration effectiveness of four commercially available microaggregate filters was determined using 14-day-old stored human blood in a constant infusion system. All filters significantly reduced the volumes of microaggregates contained in 500 ml. of blood. Three of the filters tested either occluded or failed to effectively remove microdebris from larger volumes of blood. These filters should be employed only for single blood transfusions. A fourth filter--of grid design--was effective in removing microdebris from 2,000 ml. of blood, the limits of the study. When employing microaggregate filters in massive transfusion situations for the prevention of pulmonary dysfunction, filtration characteristics and efficiencies of the filters employed must be known so that inadvertent administration of microdebris to the patient might be prevented.
在一个恒流输注系统中，使用储存14天的人体血液测定了四种市售微聚集体过滤器的过滤效果。所有过滤器均显著减少了500毫升血液中所含微聚集体的体积。所测试的三种过滤器要么堵塞，要么未能有效去除大量血液中的微碎片。这些过滤器仅应用于单次输血。第四种呈网格设计的过滤器能够有效去除2000毫升血液（该研究的极限量）中的微碎片。在大量输血情况下使用微聚集体过滤器以预防肺功能障碍时，必须了解所使用过滤器的过滤特性和效率，从而防止不慎将微碎片输入患者体内。
