Acute coagulopathy of trauma (aCOT) is a state of disordered coagulation developing soon after severe injury and blood loss and has been defined in the clinical literature as an elevation in prothrombin time (PT) and activated partial thromboplastin time (aPTT). ⋯ This model of aCOT in rats showed complex changes in clotting parameters over 4 h that included a rise in PT and aPTT. At 4 h, there was a decrease in clotting firmness, even though the clot formation was faster (elevated α angle and decrease in clotting time). The decrease in clotting firmness correlated with falling fibrinogen and platelet count. This model affords an opportunity to evaluate interventions in the treatment of aCOT.
