Initial therapy of shock in the emergency department emphasizes the normalization of hemodynamic variables e.g. heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP) rather than optimization of systemic and regional oxygenation. Central venous oximetry (ScvO2), arterial lactic acid concentrations (Lact) and the shock index (SI) were examined during initial hemodynamic stabilization of clinical shock in the emergency room. ⋯ Measurement of ScvO2, Lact and SI may provide valuable additional information on the adequacy of systemic oxygenation and LV function during initial therapy of shock. This may identify patients who require further monitoring and intervention to optimize systemic oxygen transport and cardiac performance and reduce their morbidity and mortality.
