Cryoprecipitate, also called cryo for short, or Cryoprecipitate Antihemophilic factor (AHF), is a frozen blood product prepared from blood plasma. [1] To create cryoprecipitate, Plasma is slowly thawed to 1–6 °C. A cold-insoluble precipitate is formed, which is collected by centrifugation, resuspended in a small amount of residual plasma ...
Fresh frozen plasma (FFP) is a blood product made from the liquid portion of whole blood. [3] It is used to treat conditions in which there are low blood clotting factors (INR > 1.5) or low levels of other blood proteins. [3] [1] It may also be used as the replacement fluid in plasma exchange.
The term cryosupernatant (also called cryo-poor plasma, cryoprecipitate depleted, cryoprecipitate reduced plasma) refers to plasma from which the cryoprecipitate has been removed. It is used to treat thrombocytopenic purpura .
A blood product is any therapeutic substance prepared from human blood. [1] This includes whole blood; blood components; and plasma derivatives.Blood components include: red blood cell concentrates or suspensions; platelets produced from whole blood or via apheresis; Granulocyte, plasma; and cryoprecipitate.
Prothrombin complex concentrate, cryoprecipitate and fresh frozen plasma are commonly used coagulation factor products. Recombinant activated human factor VII is sometimes used in the treatment of major bleeding. Tranexamic acid and aminocaproic acid inhibit fibrinolysis and lead to a de facto reduced bleeding rate.
It differs from fresh-frozen plasma (FFP) in that it is frozen within 24 hours of blood collection, whereas FFP is frozen within 8 hours. The phrase "FFP" is sometimes used to refer to any frozen blood plasma product intended for transfusion. PF24 is stored, thawed, and infused with the same procedures used for FFP.
For apheresis platelet donation the donor's pre platelet count should be above 150 x 10^9/L. For apheresis plasma donation, the donor's total protein level should be greater than 60 g/L. For double red cell apheresis, donors of either gender require a minimum hemoglobin level of 14.0 g/dl.
Packed red blood cells, fresh frozen plasma, and platelets are generally administered. [131] Typical ratios of fresh frozen plasma, platelets and packed red blood cells are between 1:1:1 and 1:1:2. [132] In some locations, blood has begun to be administered pre-hospital in an effort to reduce preventable deaths from significant blood loss.
