Storage of Platelet Concentrates

Transfusion, 1976
The American National Red Cross has initiated a cooperative clinical study designed to evaluate the therapeutic effectiveness of fresh platelets and platelets stored at 4 or 22 C for up to 72 hours. Preliminary results, in confirmation of earlier work, indicate an inverse relationship between platelet count and bleeding time in patients with ...

Platelet counting using plasma platelet concentrate samples

Transfusion Medicine, 1992
SUMMARY. Platelet counting using samples of plasma from platelet concentrates prepared for transfusion was assessed. The methods employed included a manual phase‐contrast method, and counting with Coulter S Plus and Sysmex E‐2500 counters. All methods were reproducible (mean CV of 4.9, 2.2 and 1.4%, respectively).

Preparation of Platelet Concentrates

2011
Platelets are specialized blood cells that play central roles in physiologic and pathologic processes of hemostasis, wound healing, host defense, thrombosis, inflammation, and tumor metastasis. Activation of platelets is crucial for platelet function that includes a complex interplay of adhesion, signaling molecules, and release of bioactive factors ...

Monocyte Activation in Platelet Concentrates

Vox Sanguinis, 1998
Abstract Background and Objectives: Cytokines in platelet concentrates contribute to febrile transfusion reactions. Activated monocytes are a major source of inflammatory cytokines, however the role of monocytes in cytokine production in platelet concentrates has not been clarified.

Extension of platelet concentrate storage

Transfusion, 1983
Extension of the storage time of platelet concentrates in a satellite bag which is part of a new blood bag system was studied by reinfusing autologous 51Cr‐labeled platelets into normal volunteers, and measuring postinfusion platelet counts and bleeding times in patients requiring platelet transfusions.

Bacterial proliferation in platelet concentrates

Transfusion, 1986
ABSTRACT: Growth curves of bacteria in platelet concentrates were studied to determine whether increasing the shelf‐life of platelets from 3 to 7 days might have contributed to the increased number of deaths caused by contaminated platelets that have been reported to the FDA since 1980.

Chemokines in stored platelet concentrates

Transfusion, 1996
BACKGROUND: Platelets contain several mediators, belonging to a family of proinflammatory cytokines named chemokines, that are stored in the organelles. Release and accumulation of these chemokines during storage of platelet concentrates (PCs) might be responsible for nonhemolytic transfusion reactions.STUDY DESIGN AND METHODS: Analysis was done of pH ...
