Banked Blood Microfiltration II. DACRON-WOOL MICROFILTER

Abstract
It is well established that debris tends to accumulate in banked blood, the amount of debris increasing with storage time. If such blood is transfused to a patient, it will be filtered by the capillary network of the lungs and could cause various intensities of microemboli. These can be prevented by microfiltration- the Swank IL200 transfusion filter made of Dacron wool is perfectly suitable. It removes more than 70% of the debris 29-100 .mu.m size from 4 blood units, and its efficiency for particle removal is greatly increased by lactate priming.
