Effects of a Goal-directed Hemodynamic Therapy Driven by ECOM on Morbidity and Mortality After Cardiac Surgery?

"goal directed hemodynamic therapy is based on the ECOM evaluation of stroke volume variation (SVV) \& cardiac index (CI).~goals:~* SVV \< 11%~* IC \> 2,2 ml/min/m²~During the anesthesia"

"goal directed hemodynamic therapy will be set and performed by the attending anesthetist, based on the analysis of further clinical parameters: Standard monitoring : heart rate, saturation index~* Diuresis \> 0,5ml/kg/h~* Blood pressure , PAM \> 65 mmHg~* Pulse pressure variation~* CVP 8 to 12 cmH20~* Visual aspect of the heart~* Overload signs During the anesthesia"
