Maintaining the plasma fibrinogen concentration is important to limit excessive perioperative blood loss. This article considers the evidence for this statement, and questions the justification for using cryoprecipitate rather than virus-inactivated fibrinogen concentrate to support plasma fibrinogen levels. Haemophilia was historically treated with cryoprecipitate, but specific coagulation factor concentrates are now preferred. ⋯ In conclusion, wider availability and use of fibrinogen concentrate may improve the management of perioperative bleeding. Further benefits may accrue from more rapid and accurate techniques for monitoring fibrinogen levels. Clinical studies are needed to evaluate methods of measuring fibrinogen and assessing fibrin polymerization, and to define critical haemostatic plasma fibrinogen concentrations in different perioperative situations.
