Fibrinogen Replacement: A Questionable Dogma.

Abstract

Management of hemostasis in the perioperative setting, in trauma or in acute care, has considerably changed over the last two decades. Viscoelastic testing and single-factor replacement therapies have become cornerstones of the respective clinical approaches. Here, we illuminate the basic theories for these approaches as well as the important evidence available. Both viscoelastic assays and single-factor replacements are important improvements; their use must be based on the strongest scientific evidence available.
