ABSTRACT
AIM: The aim of this study was to validate the classification of hypovolaemic shock given by the Advanced Trauma Life Support (ATLS). METHODS: Patients derived from the TraumaRegister DGU(®) database between 2002 and 2010 were analyzed. First, patients were allocated into the four classes of hypovolaemic shock by matching the combination of heart rate (HR), systolic blood pressure (SBP) and Glasgow Coma Scale (GCS) according to ATLS. Second, patients were classified by only one parameter (HR, SBP or GCS) according to the ATLS classification and the corresponding changes of the remaining two parameters were assessed within these four groups. Analyses of demographic, injury and therapy characteristics were performed as well. RESULTS: 36,504 patients were identified for further analysis. Only 3411 patients (9.3%) could be adequately classified according to ATLS, whereas 33,093 did not match the combination of all three criteria given by ATLS. When patients were grouped by HR, there was only a slight reduction of SBP associated with tachycardia. The median GCS declined from 12 to 3. When grouped by SBP, GCS dropped from 13 to 3 while there was no relevant tachycardia observed in any group. Patients with a GCS=15 presented normotensive and with a HR of 88/min, whereas patients with a GCS<12 showed a slight reduced SBP of 117mmHg and HR was unaltered. CONCLUSION: This study indicates that the ATLS classification of hypovolaemic shock does not seem to reflect clinical reality accurately.

Of all trauma-related deaths 40% are due to exsanguination. The causes for acute, hemorrhaging are uncontrolled bleeding sources and the development of acute posttraumatic coagulopathy. Clinical observations and recent research results emphasize the key role of this disorder in acute trauma care. The present synopsis summarizes the results from different analyses based on datasets from severely injured patients derived from the Trauma Register of the German Trauma Society (DGU) on frequency, potential triggers and strategies to manage acute posttraumatic coagulopathy. In an extension to this work a clinical scoring system for early identification of patients at high risk for ongoing bleeding is presented. High risk patients seem to benefit from a more balanced transfusion regimen.
