EFFECT OF MICROPORE FILTRATION ON PULMONARY-FUNCTION AFTER MASSIVE TRANSFUSION

1. 1. This study demonstrates a positive correlation between the number and size of infused microaggregates and the subsequent abnormality in pulmonary function as measured by oxygenation and dead space. 2. 2. No such correlation between the severity of injury and the altered pulmonary function or transfusion volume was demonstrated. 3. 3. We were unable to demonstrate an advantage to the use of a 40 μ micropore filter in preventing the adult respiratory distress syndrome (ARDS) or in improving pulmonary function in our patients. 4. 4. One explanation for the failure to demonstrate such an advantage is the low efficiency of the filter used. © 1979.
