Thromboelastometry in trauma care: a place in the 2018 Belgian health care system?

Introduction Evidence supporting the use of Thromboelastography (TEG®) and rotational thromboelastometric (ROTEM®) in the trauma setting remains limited. We present the results of a practical evaluation of the potential interest of ROTEM® in the diagnosis of acute coagulopathy and the need for emergent blood product transfusion in the general trauma population of a non-trauma Belgian emergency department. Methods Extracting a convenience cohort from the initial prospective TICCS study, we performed a retrospective analysis to test the following hypothesis: ROTEM® might be helpful to discriminate trauma patients with or without acute coagulopathy. Fifty patients were included and ROTEM® results were compared to conventional coagulation tests results, blood transfusion need and outcome. Results With a negative predictive value of 97.6% and a positive predictive value of 42.9%, a strictly normal ROTEM® profile at the time of admission seems to be able to exclude the presence of acute coagulopathy. ROTEM® also seems to be accurate in identifying patients without the need for emergent blood product transfusions. Conclusion In a population of trauma patients of a Belgian general emergency department, a strictly normal coagulation profile evaluated by ROTEM® at hospital entry is associated with a normal coagulation profile evaluated by INR and fibrinogen levels and the absence of any indication of blood product transfusion. ROTEM® may be useful for preselection of trauma patients at risk for coagulopathy within the global trauma population. This, however, would need confirmation in further investigations.
