Renal Replacement Therapy in Acute Kidney Injury: Which Mode and When?

Renal replacement therapy (RRT) for acute kidney injury (AKI) patients in an intensive care unit (ICU) presents unique problems of providing biochemical and fluid removal in patients with unstable circulations, inotropes, and increased capillary permeability. Although no individual modality has been shown to confer a mortality benefit, it is assumed that continuous therapies like peritoneal dialysis (PD) and venovenous hemofiltration or hemodiafiltration may be better tolerated by the patient with hemodynamic instability, raised intracranial pressure (ICP), and liver failure. An individual patient may require more than one treatment in the course of his/her illness. The therapies offered may reflect available resources, local expertise, and cost constraints.
