Autologous blood transfusion has many advantages compared with allotransfusion. We designed a method for producing autologous red cell concentrates (RCC) by using a membrane plasma separator (Hydrophylized polyethylene, 0.2m2, Asahi Medical Co. Ltd.). The subjects were six benign prostatic hypertrophy patients (mean age: 68.3yrs) who needed transurethral resection of the prostate (TUR-P) and one healthy volunteer (27yrs). About 200ml of autologous RCC was collected from the patient each time at one and two week bafore operation and was used at TUR-P. Mean Ht value before blood taking (N-12) was 46.8±3.2% and that of the RCC was 60.1±5.8%. The changes of leucocyte count and complements concentrations (CH50, C3c and C4) during the sampling operation were not remarkable. Accordingly, the transfusion of RCC produced by using a membrane plasma separator is clinically worthapplying, especially among elderly patients because it induces a minimal increase of the circulating volume.
