Platelets correspond to one of the most widely used blood components in transfusion medicine, given their importance in the prevention of bleeding disorders in patients with multifactorial thrombocytopenia and non-immunological etiology, as well as in the management of traumatic or blood-related bleeding. surgical treatments. Given its wide margin of use and the constant demand for it for use within the different management schemes and procedures associated with the medical act, it is the objective of both hemotherapy services and blood banks and blood products to have availability component constant to meet such requirements. The main problem of this resource is its short useful life (5 to 7 days) which limits its availability, especially in the Latin American context where the production of blood components as well as the resources allocated for this purpose by state entities to blood banks are generally limited. Cryopreservation at -80 ° C using Dimethylsulfoxide as a preservative solution is a technique used since the 1950s to prolong platelet survival, the improvement of which has been remarkable in recent years, thus constituting an alternative for the resolution of this problem.
