Biomarker-guided Intervention to Prevent Acute Kidney Injury

There is no specific therapy for acute kidney injury. It is presumed that supportive measures improve the care and outcome of patients with acute kidney injury. The investigators hypothesize that the implementation of a bundle of supportive measures adapted to patients undergoing major surgery reduces the occurrence of AKI. This randomized prospective multicenter trial is needed to investigator whether the implementation of the bundle of measures is effective to prevent AKI in high risk patients undergoing major surgery.
