Brief Summary

Fluid management is one of the key issues in the initial management of septic shock (SS). Fluid overload and hypovolemia have been associated with increased mortality in several trials. Transthoracic echocardiography (TTE) and lung ultrasound are recommended for haemodynamic assessment in critically ill patients. However, the benefit of hemodynamic optimisation using echography has not been yet evaluated. The purpose of this multicenter, controlled, randomized trial is to assess the impact of an echocardiographic algorithm of hemodynamic optimization on fluid management in septic patients during the first 4 days of therapy.

GroupInterventionDescription
Interventional Strategy: STOPFLUID AlgorithmEchographic hemodynamic algorithm guiding fluid resuscitationFluid management is optimised using the specific echographic hemodynamic algorithm ('STOPFLUID') of this study described during the first 4 days of septic shock. Fluid bolus will not be administered in case of increased left ventricle filling pressures; fluid challenge will be performed based on dynamic indices and fluid depletion will be considered on the basis of Lung UltraSound (LUS) assessment.
