[Leukocyte removability of a newly developed filter, RC-100, in rapid transfusion].
Leukocyte-depleted blood products are currently a burning issue in transfusion medicine. As methods for depleting leukocytes, the bedside filters are shown to have a high removal rate and several kinds of them are in use. We investigated the leukocytes removal rate of a new filter RC-100 (Pall Co., Glen Cove, NY) under the condition of rapid rate of transfusion during operations. In flow rates of 30, 60, 100 ml.min-1, the removal rate of leukocytes for CRC were 99.9 +/- 0.06, 100.0 +/- 0.00 and 99.4 +/- 0.20% respectively, and for WB 100.0 +/- 0.00, 99.9 +/- 0.10 and 99.1 +/- 0.70%, respectively. The recovery rates of erythrocytes were not significantly decreased for CRC and for WB in all flow rates. These results suggest that RC-100 could be useful either for CRC and for WB even with the rapid flow rate under 100 ml.min-1.
