Cryoprecipitate is derived from fresh frozen plasma (FFP), which is frozen within 8 hours of collection. 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. 8600 Rockville Pike Outcomes Following Three-Factor Inactive Prothrombin Complex Concentrate Versus Recombinant Activated Factor VII Administration During Cardiac Surgery. 0000005449 00000 n Review both the approved and off-label indications for using prothrombin complex concentrate. Prophylactic fibrinogen infusion reduces bleeding after coronary artery bypass surgery. This extrapolates to ~1 thromboembolic event per 23,300 doses of 4 g of fibrinogen concentrate or an absolute risk of 0.004%. JAMA. In patients weighing greater than 100 kg, the recommendation is to exceed the maximum dose. Thromb Haemost. 47. Pro-coagulant haemostatic factors for the prevention and treatment of bleeding in people without haemophilia. Whether to use fibrinogen concentrate or cryoprecipitate as a first-line therapy for the treatment of acquired hypofibrinogenemia in the cardiac surgical patients continues to be a subject of intense debate in the United States. 19. Br J Anaesth. Fibrinogen and hemostasis: a primary hemostatic target for the management of acquired bleeding. Another advantage of fibrinogen concentrate is that it can be rapidly reconstituted and administered to patients. 15. 48. 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. 2013; 117:1422. Repeat or subsequent dosing is not recommended. Cryoprecipitate - (See "Clinical use of Cryoprecipitate" .) Life-threatening Major Bleed With a Non-Warfarin Anticoagulant. In vitro and observational studies have demonstrated the importance of fibrinogen replacement for adequate hemostasis, yet randomized controlled trials of fibrinogen treatment compared to placebo have not shown a mortality benefit.19 Cushing and Haas20 examined these clinical trials and determined that fibrinogens inconsistent efficacy may be related to design flaws in the trials themselves, including variable definitions for hypofibrinogenemia, inclusion of patients with insignificant bleeding, and off-protocol interventions. In the Randomized Evaluation of Fibrinogen Versus Placebo in Complex Cardiovascular Surgery (REPLACE) trial, 152 patients undergoing elective aortic replacement surgery were randomized to receive either fibrinogen concentrate or placebo, depending on whether there was a bleeding mass of 60250 g on surgical packing post-CPB. A major criticism of these studies is that patients received fibrinogen concentrate without demonstrating low fibrinogen concentration, and in 1 trial, without clinically significant bleeding, because fibrinogen concentrate was given before surgery.
