Abstrakt: Objective: To compare the efficiency of 20 and 40 μm arterial line filters during cardiopulmonary bypass for the removal of emboli from the extracorporeal circuit. Methods: Twenty-four adult patients undergoing surgery were perfused using a cardiopulmonary bypass circuit containing either a 20 μm or 40 μm arterial filter (n = 12 in both groups). The Emboli Detection and Classification system was used to count emboli upstream and downstream of the filter throughout cardiopulmonary bypass. The mean proportion of emboli removed by the filter was compared between the groups. Results: The 20 μm filter removed a significantly greater proportion of incoming emboli (0.621) than the 40 μm filter (0.334) (p=0.029). The superiority of the 20 μm filter persisted across all size groups of emboli larger than the pore size of the 40 μm filter. Conclusion: The 20 μm filter removed substantially more emboli than the 40 μm filter during cardiopulmonary bypass in this comparison. [ABSTRACT FROM AUTHOR]
