What researchers measure

Primary outcomes

  1. 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)
