Abstract
A 4-year old male Australian Cattle Dog involved in a road traffic accident was presented with severe polytrauma to the Small Animal Clinic, University of Zurich. He was presented in hemorrhagic shock, with an initial lactate of 10.3mmol/l and ongoing bleeding from multiple injury sites. Acute traumatic coagulopathy diagnosed with ROTEM within one hour after accident showed marked hypocoagulation and hyperfibrinolysis. Treatment with a total dose of 40mg/kg of tranexamic acid intravenously resulted in successful elimination of hyperfibrinolysis in the following, serially measured ROTEM tracings.
