    Author: Moog R, Müller N.
    Journal: Transfus Sci; 1994 Sep; 15(3):313-7. PubMed ID: 10155548.
    Abstract:
    New software for the cell separators A 201 and CS 3000 Plus have been developed by Baxter. Fresenius recently offered a single needle option for the AS 104 device. The results of separation are described with respect to total platelet yield, efficiency and cell contamination of the platelet concentrate (PC). Two software programs were evaluated in both the A 201 (version 5.12 and 5.13) and AS 104 cell separators (version 4560 with different separation parameters according to protocol IV and V). With software version 5.12, the A 201 collected 2.0 +/- 0.9 x 10(11) platelets in 200 mL plasma whereas 2.3 +/- 0.7 x 10(11) platelets could be harvested with version 5.13. The separation efficiencies were 32.1 +/- 11.6 and 34.7 +/- 10.7%, respectively. The leucocyte contamination was 5.6 +/- 4.6 x 10(8) with software version 5.12 and 4.9 +/- 7.6 x 10(8) with the 5.13 version. With the CS 3000 Plus cell separator, 2.9 +/- 0.8 x 10(11) platelets (efficiency 38.4 +/- 8.2%) could be harvested in 208 +/- 2 mL plasma. The white blood cell contamination was extremely low (1.4 +/- 3.2 x 10(6). There was a high separation efficacy with the Fresenius single needle procedure of 59.1 +/- 10.6% (protocol IV) and 58.7 +/- 7.3% (protocol V), respectively. The total number of platelets sampled in 338 +/- 21 mL plasma was 3.1 +/- 0.8 x 10(11) in protocol IV.(ABSTRACT TRUNCATED AT 250 WORDS)
