During massive hemorrhage, thawing time may be detrimental, leading to an additional hemodilution or consumptive coagulopathy, as the minimal fibrinogen is given in other allogeneic blood products. Cryoprecipitate (Table 3.6) is made by thawing UK donor FFP at 4C, producing a cryoglobulin rich in fibrinogen, Factor VIII and von Willebrand factor. Kasper CK. PCC dosing products are expressed as units of factor IX. endobj PCC contains significantly higher amounts of the clotting factors compared to FFP; one dose of PCC equals 8 to 16 units of FFP. 39 0 obj In a review of 14 individual studies of the reversal of warfarin anticoagulation, there were five thrombotic events in 308 patients who received 4-factor prothrombin complex concentrates and two in 161 patients who were given 3-factor prothrombin complex concentrates, although none of the adverse events was deemed clinically significant [11].The risk is therefore low, but it ought to be . ; Society of Thoracic Surgeons Blood Conservation Guideline Task F. 2011 update to the Society of Thoracic Surgeons and the Society of Cardiovascular Anesthesiologists blood conservation clinical practice guidelines. In a recent economic analysis that accounted for cryoprecipitate wastage, it was estimated that the cost of fibrinogen concentrate would need to decrease by around 40% to be competitive with cryoprecipitate in the United States.45, Another important limitation of fibrinogen concentrate is that its use in acquired hypofibrinogenemia is off-label in the United States. J Cardiothorac Vasc Anesth. You may be trying to access this site from a secured browser on the server. Although this may seem trivial, off-label drug use is associated with a 1.5-fold higher incidence of serious adverse drug events.46 Furthermore, a significant amount of pharmacovigilance time may be needed to identify a pattern of increased thromboembolic risk. However, the small difference in a chest tube output observed in this study may not be clinically significant.42 The limitations of this small, single-center trial were that 6 patients (10%) in the control group were given fibrinogen concentrate postoperatively, confounding the studys results, and the chest tube output is well known to have limitations as a surrogate for bleeding.

Transfusion of platelets and/or cryoprecipitate is permitted if abnormal laboratory values are observed during the rewarming phase of CPB; platelet count <100 x 103/l, and fibrinogen <200 mg/dl, respectively. Low levels of factor XIII are associated with increased postoperative bleeding and reoperation for bleeding in the cardiac surgery.55 Factor XIII administration was previously found to reduce blood loss in the CABG patients, when given at a dose of 1250 or 2500 IU.56 Unfortunately, these results were not replicated in a larger study of cardiac surgical patients, where 17.5 and 35 IU/kg doses were administered, and there was no reduction in allogeneic transfusion or reoperation.57 Nevertheless, in patients with excessive hemodilution or in those with major blood loss, the additional factor XIII activity that is present in the cryoprecipitate may be beneficial in achieving hemostasis. 2004. endobj Haemophilia.

Bilecen S, de Groot JA, Kalkman CJ, et al. 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. 31 However, there is continuing controversy over which component is preferable, and this, in part, reflects a lack of clinical trials comparing the two components.

Crit Care. Instead, cryoprecipitate is used to treat acquired hypofibrinogenemia in cardiac surgery, multitrauma, obstetrical hemorrhage, and other critical care settings.12 Until recently, cryoprecipitate was the only effective treatment for acquired hypofibrinogenemia in cardiac surgical patients. 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.

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. 23. Full size image Patients in the FP group were slightly older, heavier, more likely to be male, and more likely to undergo non-elective surgery.

Furthermore, evidence supporting the routine or prophylactic use of fibrinogen concentrate in the cardiac surgical patients is not robust, and larger studies are needed to confirm its value compared to cryoprecipitate, which has been the gold standard for treating acquired hypofibrinogenemia for almost 50 years. 2014; 54:109118.
