Cryoprecipitate contains fibrinogen, Factor VIII, Factor XIII and vWF. In many clinical contexts, use of cryoprecipitate has been replaced with use of clotting factor concentrates (where available), but the whole form is still routinely stocked by many hospital Blood bank.
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 .
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. Some products for topical use, such as serum eye drops, have also been recently classified as blood components. [2]
ABO blood group antigens present on red blood cells and IgM antibodies present in the serum. The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes (red blood cells). [1]
Red blood cell concentrates, also known as red cell concentrates or packed red blood cells, are red blood cells that have been separated for blood transfusion. [1] A red blood cell concentrate typically has a haematocrit of 0.50 – 0.70 L/L and a volume between 250 and 320 mL.
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.
Platelets are either isolated from collected units of whole blood and pooled to make a therapeutic dose, or collected by platelet apheresis: blood is taken from the donor, passed through a device which removes the platelets, and the remainder is returned to the donor in a closed loop. The industry standard is for platelets to be tested for ...
Acute normovolemic hemodilution (ANH) is a form of autologous transfusion where whole blood is collected from a patient at the start of surgery into a standard blood collection bag with anticoagulant with the simultaneous replacement of intracellular volume using acellular fluids (such as normal saline).
