Multicenter Study Observational Study
The coagulopathy underlying rotational thromboelastometry derangements in trauma patients: a prospective observational multicenter study.
Viscoelastic hemostatic assays such as rotational thromboelastometry (ROTEM) are used to guide treatment of trauma induced coagulopathy. The authors hypothesized that ROTEM derangements reflect specific coagulation factor deficiencies after trauma. ⋯ Coagulation factor levels and mortality in the group with an isolated clotting time prolongation are similar to those of patients with a normal ROTEM. Other ROTEM derangements are associated with mortality and reflect a depletion of fibrinogen and factor V. Increased fibrinolysis can be present when the lysis index after 30 min is normal.
