[Application of ultrafiltration during cardiopulmonary bypass].
The ultrafiltration (UF) was employed in 20 patients undergoing open-heart operation with cardiopulmonary bypass (CPB). The number of controls was 10. The average UF duration was 24.7 +/- 9.6 min (12-49) and the average amount of ultrafiltrate was 1433.5 +/- 482.6 ml (650-2,350 ml). The volume load of UF group was similar with that of the control group. The output volume of UF group was greater than that of the control group (P less than 0.01). After UF, the degree of increase in hematocrit, plasma albumin and total plasma protein was 33.8%, 34.7%, and 26.0%, respectively. Moreover, we did not find any abnormal increase in blood viscosity. No additional adverse actions of UF were found.
