Recovery, life span, and function of stored plateletpheresis units.
Plateletpheresis units collected using the Haemonetics Model 30 or the IBM 2997 cell separator were stored for 24 h at 22 degrees C. Autologous recovery and life span measurements averaged 64 +/- 13% (1 SD) and 8.9 +/- 1.3 (1 SD) 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/microliter/m2, respectively, and the bleeding time showed improvement in each patient. There was no significant difference in these parameters between collection devices.
