Crit Care. Although fibrinogen concentrate is now extensively used in Europe and Canada, there remains debate in the United States about whether a fibrinogen concentrate is superior when compared to a cryoprecipitate for treating acquired hypofibrinogenemia in the cardiac surgical patients. Direct oral anticoagulation agents have a different mechanism of action: apixaban and rivaroxabanare inhibitors of factor Xa, and dabigatran inhibits thrombin. The main risk factor for developing thrombosis is the accumulation of factor II, which can occur with large or frequent dosing. Package insert. 9.

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.

However, because fibrinogen concentrate lacks the other components contained in the cryoprecipitate, it may not be the ideal product for replacing fibrinogen in all cardiac surgical patients, particularly those with longer cardiopulmonary bypass duration. 35. Cryoprecipitate was serendipitously discovered by Judith Graham Pool in the 1960s at Stanford University.10,11 Dr Pool noted that when plasma was thawed, very little factor VIII was present in the supernatant, whereas abundant factor VIII was present in the unthawed material at the bottom of the container.

Administration of Prothrombin Complex Concentrate vs. Standard 48. 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. The total median dose requirement for 4-factor PCC was 1000 units (15 units/kg) and 2 mg (20 mcg/kg) for rFVIIa.

Activation of PARs lead to the release of adenosine diphosphate (ADP) from dense granules and activation of the platelet surface glycoprotein IIb/IIIa receptor, which binds activated platelets to fibrinogen/fibrin.5,6, Clot strength is dependent on fibrinogen concentration, and multiple studies have shown that a fibrinogen concentration of >200 mg/dL is necessary for optimal hemostasis in cardiac surgical patients.3,7 The European guidelines recommend replacing fibrinogen when its concentration is <150 mg/dL in the noncardiac surgical patients.8 Clot firmness and plasma fibrinogen concentration predictably fall after cardiopulmonary bypass (CPB), mainly due to hemodilution and a lesser degree from consumption.2 Decreases in clotting factors of 30%50% are common after CPB and depend on CPB priming volume, retrograde autologous priming (RAP), autologous whole blood collection before CPB, and the amount of cell salvage.4,9. 1990; 93:694697. 27.
