POLYMORPHISM OF COLLECTION, TRANSFUSION AND EFFECTIVENESS OF DONOR PLATELETS CONCENTRATES.

There were compared the results of 520 platelets transfusions in 8 centers. In the surveyed organizations part of prophylactic platelet transfusions ranged from 10% to 91%. On average platelet transfusions for the prevention of bleeding in 3,6 times more often than to stop the bleeding. 67,5% ofrecipients ofplatelets have oncology diseases. Target platelet concentrations for preventive transfusions seems high compared to modern evidence-based value - 10 @. 10⁰/l. 25% ofprophylactic transfusions included in the study were performed in patients with platelet count of 30 @. 10⁰l or more. In 76,7% of transfusions used platelet concentrates prepared by apheresis. Single whole blood- derived-units are used at 3,7 times more often than pooled platelets.
