Viscoelastic haemostatic assays and fibrinogen concentration tests during haemodilution: The effects of fibrinogen and factor XIII
Background: The efficacy of concentrates of fibrinogen and factor XIII in hypothermia and haemodilution has not yet been completely investigated. Clauss methods have not previously been evaluated perioperatively. Methods: Coagulation was assessed with rotational thromboelastometry (ROTEM) or free oscillation rheometry (FOR) in vitro and different fibrinogen measurement methods in observational stu
