Acute Renal Failure in Critically Ill Patients: Current Evidence-Based Practices.

Acute kidney injury (AKI) is a common condition amongst critically ill patients in the medical intensive care unit (ICU) and is associated with increased morbidity and mortality. There are several areas of ongoing debate regarding management of AKI, specifically the initiation and timing of renal replacement therapy (RRT). In this review, we aim to concisely discuss epidemiology, current evidence with regards to optimal vascular access, timing of initiation and modality of renal replacement therapy in acute kidney injury in critically ill patients.
