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 ...

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 ...

Platelet Activity in Washed Platelet Concentrates

Anesthesia & Analgesia, 2004
Life-threatening anaphylaxis or febrile nonhemolytic transfusion reactions after transfusion of platelet concentrates (PCs) is a serious clinical problem caused by the sensitizing of recipients to plasma components, such as immunoglobulin A, or by cytokines. There is a possible indication for washing of PCs in these thrombocytopenic patients.

Effects of high platelet concentration in collecting and freezing dry platelets concentrates

Transfusion and Apheresis Science, 2004
To evaluate, in vitro, the effects of collecting and cryopreserving fresh dry platelet concentrates (PCs).Standard and dry PCs were collected in the same apheresis procedure. PCs were evaluated by mean platelet volume (MPV), pH, glucose and LDH levels.

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.

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 ...

Preparation and Storage of Platelet Concentrates

Transfusion, 1976
A technique of platelet concentrate preparation and storage is presented which permits the maximum number of viable and functional platelets to be preserved for periods of 72 hours. Although the storage conditions must be followed precisely, the method is nevertheless simple to perform and does not require specialized expensive equipment.

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.
