Prehospital Shock Index in severe trauma patients.

Shock Index (SI) is defined as the ratio of the Heart Rate (HR) to systolic Blood Pressure (BP). In place of HR or BP alone, SI has been used as a guide for diagnosing of acute hypovolemia, even in the presence of normal HR or BP. Pre-hospital SI also seems to correlate with mortality (1). We present here a retrospective analyze of the 82 trauma patients initially included in the study evaluating the Trauma-Induced Coagulopathy Clinical Score TICCS (2). The aim of this analyze was to determine if pre-hospital SI is correlated with acidosis and mortality
