The purpose of this study is to verify any existing relationship between mixed oxygen saturation (from central venous catheter) and urinary sodium, potassium, chloride in determining the volemic state and renal perfusion of patients undergoing major surgical interventions.
Determination of mixed oxygen saturation in central venous blood (ScvO2) and three urinary electrolytes (sodium, potassium, chloride) [ Time Frame: During the stay of the patient in the operating room (in average 6 hours) and the eventual stay in the post-surgery intensive care unit (in average 1 day) ]
