Abstract:
Platelet concentrates (PC) were prepared from CPD-blood using PL-146 triple bag system (Fenwal). They were stored in 60 ml plasma at room temperature for 72 h with gentle agitation by side-over-side rotation with 2 rpm. PC contained on average more than 0.55.10(11) platelets form 450 ml blood. There were significant correlations between pH-values and platelet number as well as percentage of disc-shaped platelets. pH-values, number of platelets and morphology were well maintained in all PC, but 4 of 18 had pH-values below 6.0 after 72 h. This means that 95% of the stored PC had sufficient quality after 48 h and only 78% had it after 72 h.
