Prothrombin Complex Concentrate Article - StatPearls 0 2020. A recent meta-analysis of randomized controlled trials of fibrinogen concentrate in the cardiac surgical patients suggested that the fibrinogen concentrate decreases RBC transfusion (relative risk [RR] = 0.64; 95% CI, 0.49-0.83), but there was no reduction in other transfusions (eg, platelets and plasma), and there was no reduction in the reoperations for bleeding.49 Taken together, the current evidence supporting the routine use of fibrinogen concentrate in the cardiac surgical patients is not particularly strong, even when the treatment is based on the whole blood viscoelastic coagulation testing.

It remains unclear whether fibrinogen concentrate will have equal efficacy in these types of cases where CPB duration is 200300 minutes.24, Fibrinogen concentrate is very costly in the United States.

The patients in the rFVIIa group, required more cryoprecipitate than those in the 4-factor PCC group (4-factor PCC: 2 units (range 0-6) vs. rFVIIa: 2 units (range 0-8), p = 0.03). 10.

Patient presents within 3 to 5 half-lives of the drug (half-life is around 12 hours for apixaban and 5 to 9 hours for rivaroxaban) - this window (3 to 5 half-lives)can be extended if renal impairment is present and sufficient to prolong the half-life of the medication. Sec. 2017. Patients were included if they were at least 18 years of age and had undergone cardiac surgery with bleeding requiring intervention with 4-factor PCC or rFVIIa. The mechanism of action of PCC in reversing anticoagulation with DOACs remains unestablished. Factors affecting the quality of cryoprecipitate. Due to plasmas low fibrinogen content of 500600 mg per 250 mL, plasma fibrinogen concentration is likely to remain low, while awaiting cryoprecipitate.31, With any allogeneic transfusion, including cryoprecipitate, there is a risk of alloimmunization and allergic transfusion reaction.32 Fibrinogen concentrate undergoes viral inactivation processing, which also removes blood and human leukocyte antigen (HLA) antibodies and antigens and significantly reduces the risk of immunological transfusion reaction.12 Transfusion-associated circulatory overload (TACO), transfusion-related acute lung injury (TRALI), and allergic transfusion reactions remain significant risks of allogeneic blood transfusion and are associated with increased health care cost, morbidity, and mortality.33,34. The shelf life is also much longer for fibrinogen concentrate (3 years) compared to cryoprecipitate (1 year), which may be important in smaller, rural hospitals that have a less frequent need for fibrinogen therapy.61 There is also a longer shelf life after reconstitution because fibrinogen concentrate is able to be used for 24 hours after reconstitution versus 6 hours after cryoprecipitate thaws. It was developed as a treatment for haemophilia but this use has now been replaced by Factor VIII concentrate. The proportion of patients assigned to either cryoprecipitate or fibrinogen concentrate as part of the original FIBRES study arm was not different (P = 0.14).
