Abstract
Acute kidney injury (AKI) commonly occurs in the intensive care unit and is associated
with significant morbidity and mortality. Patients with AKI often require initiation
of dialysis to control electrolytes, metabolic abnormalities, and volume status. This
review will discuss controversies in renal replacement therapy (RRT), including timing
of dialysis initiation, dialysis modality and dose, nonrenal indications for dialysis,
and the patient population best suited for RRT therapy.
