Drug classBlood product[1]

Cryoprecipitate, also called cryo, is a blood product made from blood plasma.[1] Uses include blood clotting problems, such as obstetrical bleeding or DIC, due to low fibrinogen; and congenital afibrinogenemia.[2][3][1] While it has be used for hemophilia A or von Willebrand disease, more specific clotting factor concentrates are preferred.[4] It is given by injection into a vein.[5] Cross-matching (compatibility testing) is not required, though matching the ABO groups is preferred if possible.[4] It is often given to adults as two 5-unit pools.[4][3]

Side effects may include fever, allergic reactions, acute hemolytic reaction, TRALI, and infections.[4] It should generally not be used in urinary tract bleeding.[1] It is made by thawing fresh frozen plasma at 4 °C then centrifuging and collecting the precipitate.[1][4] This is then resuspended in a small amount of residual plasma (generally 15 to 30 mL) and is re-frozen for storage.[4][3] It contains factor VIII, von Willebrand factor (VWF), fibrinogen, fibronectin, and factor XIII.[3]

Cryoprecipitate was developed in 1964 by Judith Pool.[6][7] It was the first treatment for hemophilia A.[1] It is on the World Health Organization's List of Essential Medicines.[5] It can be stored at -25 °C for up to a year and a half.[3] After thawing and at room temperature it should be used within 4 hours.[3] It costs the NHS about £181 in the United Kingdom for a 5 unit pooled dose of cryoprecipitate.[3] It is less expensive then fibrinogen concentrate.[4]
