Introduction. There are at least 4 randomized controlled studies of fibrinogen concentrate in the cardiac surgical patients who did not show benefits in terms of reduced RBC transfusion, reduced platelet transfusion, or reoperations for bleeding.38,4042 Three of these studies utilized fibrinogen concentrate after CPB, and 1 utilized fibrinogen concentrate before CPB. 17.

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). In addition to vitamin K, guidelines recommend FP or pro-thrombin complex concentrates (PCC) for reversal of over-anticoagulation, but only in patients with major bleeding. 2017; 11:3339. The trial was stopped prematurely due to noninferiority being satisfied.24, Because cryoprecipitate is not a purified product and contains platelet microparticles, fibronectin, Factor VIII, and VWF, there may be an increased thromboembolic risk. Fibrinogen concentrates higher cost and lack of regulatory approval for treating acquired hypofibrinogenemia continue to be significant impediments to more widespread use in the United States despite widespread use in Canada and Europe. endobj 48.

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. 2020; 136:18881891. 2021 Sep; [PubMed PMID: 34463792].

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. Inactivation of viruses with solvents, detergents, pasteurization, and filtration methods is an important advantage of fibrinogen concentrate (Table 1).21,22,24 These processes significantly reduce the risk of viral transmission.

Ten to 15% of the United States blood supply is transfused in cardiac surgical patients.1 Multiple factors including fibrinogen concentration impact bleeding and transfusion risk in cardiac surgical patients.24 About 15 years ago, most European countries removed cryoprecipitate from their markets and began to use fibrinogen concentrate for the treatment of acquired hypofibrinogenemia, mainly because of its superior safety profile. 2017.
