Recovery, Life Span, and Function of Stored Plateletpheresis Units

Abstract
Plateletpheresis units collected using the Haemonetics Model 30 or the IBM 2997 cell separator were stored for 24h at 22 ° C. Autologous recovery and life span measurements averaged 64 ± 13% (1 SD) and 8.9 ± 1.3 (1SD) days. The hemostatic effectiveness of these preparations were satisfactory; the corrected increment 4–6 h and 18–24 posttransfusion was 20,400 and 13,400/μ1/m2, respectively, and the bleeding time showed improvement in each patient. There was no significant difference in these parameters between collection devices.
