Primary Outcome Measures :
  1. Determination of hemodynamic indicators (PiCCO, ScvO2, O2-delivery) and three urinary analytes (sodium, chloride, CO2 partial pressure) [ Time Frame: During the stay of the patient in the operating room (in average 8 hours) and the subsequent stay in the post-surgery intensive care unit (in average 5 days) ]
