Abstract
Polypropylene (PP, 1.0m2) and cellulose acetate (CA, 0.6m2) hemoconcentrator were used as a double filtration for cardiopulmonary bypass (CPB) and post bypass hemoconcentration. PP+CA (0.6) showed lower proteinemia during CPB compared with pp (1.0m2) or CA (1.3m2) single used filtration group. However, PP+CA decrease the added priming volume and increased the protein content of filtrate. Double filtration might be useful and effective method for CPB instead of its cost performance.
