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.
||Observational Model: Case-Only
Time Perspective: Cross-Sectional
||Hemodynamic Indexes and Renal Perfusion: Indirect Evaluation of Blood Volume Using the Association Between ScvO2 and Urinary Electrolytes in Patients Undergoing Major Surgery.
Primary Outcome Measures:
- 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) ] [ Designated as safety issue: No ]
