[Single needle results with A-201 and AS-104 cell separators].

In plateletpheresis, new single-needle techniques have been developed for the cell separators A 201 (Baxter) and AS 104 (Fresenius). These new techniques were studied concerning donation time, ACD consumption, platelet yield, separation efficiency, erythrocyte and leukocyte contamination. The total amount of thrombocytes and the separation efficiency were significantly better with the single-needle version of the AS 104 apparatus than with the A 201 device. The contamination values were significantly lower with the AS 104 machine.
