Design outcomes

Primary

Measure	Time frame
In the first 48 hours postoperatively, incidence of acute kidney injury of any stage according to Kidney Disease: Improve Global Outcome (KDIGO) criteria	—

Secondary

Measure	Time frame
1) Incidence of acute kidney injury (AKI) during hospitalization according to KDIGO criteria. 2) Analysis of the influence of cardiac output, cardiac index, oxygen delivery and mean arterial pressure during extracorporeal circulation on the incidence of AKI. 3) Analysis of the influence of AKI on ventilation, ICU and hospital length of stay. 4) Hospital and 30-day mortality. 5) Foreign blood consumption.	—
