Authors: Thin Xuan Vo, Munir Boodhwani


Acute kidney injury (AKI) is a common complication of cardiac surgery. Depending on the severity level, the incidence of AKI after cardiac surgery ranges from 3–30%, with AKI requiring renal replacement therapy in the 3% range and mild AKI in the 30% range (1,2).
