Advances in applicaiton of platelets with cold storage at 4℃ and its storage lesion / 中国输血杂志

ABSTRACT

Platelet transfusion is one of the important therapeutic methods for clinical prevention of bleeding and hemostasis. At present, agitated storage at (22±2)℃used for platelets leads to risk of bacterial growth, which limits platelet shelf life and safety in transfusion. Cold storage at 4 ℃ can significantly promote the abovementioned drawbacks and present a better hemostatic effect. Platelets storage lesion(PSL) due to the cold storage, however, may lead to platelet activation following transfusion, thus reducing the effective survival rate in vivo. This paper reviews the research advances in PSL and the application of platelets stored at 4 ℃.
