Why Give Fresh Frozen Plasma Preoperatively?

The risk of bleeding in open heart surgery or surgery on the main blood vessels in the body is high. Fresh frozen plasma is sometimes administered to these patients to reduce bleeding. It can be administered prophylactically (to prevent bleeding) or therapeutically (to treat bleeding).

Why do you give fresh frozen plasma?

Fresh frozen plasma is used for management and prevention of bleeding, as a coagulation factors replacement, and to treat thrombotic thrombocytopenic purpura (TTP).

Do you need to crossmatch fresh frozen plasma?

Because plasma from donors with type AB blood does not contain anti-ABO antibodies, it can be given to any patient and is used for emergency transfusion in patients with unknown blood types. Crossmatching of plasma is not required, since there are no RBCs in these products.
