Abstract
A single pass ultrafiltration (SPUF) with Hemo-Concentrator® (HC) was employed in 6 patients. It was expected that the blood components salvaged at the outlet of the HC would be sufficient to allow direct transfusion. At the end of bypass, the blood in the oxygenerator (1433±314ml) was pumped directly into the patient (9.5±1.8min) through the HC. Suction (-300--400mmHg) applied to the device extracted plasma water (700±163ml). SPUF concentrated diluted blood as follows; Ht from 24.2±2.6% to 42.0±4.2% and TP from 3.5±0.2g/dl to 8.1±2.6g/dl. Control group were transfused the diluted pump blood. Compared the SPUF group with the control group, there were no significant differences in the amount of postoperative bleeding and laboratory data. SPUF with the HC is an efficient, rapid and safe method for obtaining whole blood for blood conservation and volume control.
