Abstract

Platelet (PLT) transfusion is a widely used therapy in treating or preventing bleeding and hemorrhage in patients with thrombocytopenia or trauma. Compared to the relative ease of PLT transfusion, current practice for PLT storage at room temperature (RT) for up to 5 to 7 days is inefficient, costly, wasteful, and relatively unsafe. This study was a review of major advances in PLT derivative products with improved hemostatic potential and safety feature. Recent progress in understanding the PLT activation and host clearance mechanisms has led to reassessments of current and new storage conditions that employ refrigeration and/or cryopreservation to overcome storage lesions and significantly extend shelf life of PLTs with reduced risk of pathogen contamination. It is anticipated that future PLT preservation involving cold, frozen, and/or pathogen reduction strategies in proper PLT additive solutions will enable longer term and safer PLT storage.
