Abstract

Fibrinogen is involved in both primary and secondary hemostasis, playing an important role in platelet aggregation and the establishment of a fibrin network. Recent evidence suggests that very high levels of fibrinogen act as antithrombin and can reduce endogenous thrombin potential and compromise clot stability, particularly following a low tissue factor stimulus. Several laboratory methods for measuring plasma fibrinogen concentrations are available, but results vary depending on the type of method and the use of artificial colloid plasma expanders. Adopting only the Clauss method can provide erroneously high levels when used in patients who have received colloid plasma expanders. This may contribute to a hazardous delay or complete lack of treatment. Multiple in vitro experiments, animal studies, and proof-of-principle randomized, clinical studies have recently suggested that hemostatic intervention with a fibrinogen concentrate may be efficient and safe in controling perioperative bleeding. In particular, fibrinogen concentrate has a key role in improving clotting function and reducing blood loss in settings such as trauma and cardiothoracic surgery. However, prospective studies are needed to determine the clinical efficacy and safety of fibrinogen concentrate when used as a hemostatic intervention for patients with massive bleeding due to trauma or surgery.
