Renal support in acute kidney injury

Abstract

Acute kidney injury requiring renal replacement therapy (RRT) is associated with an unacceptably high mortality rate. Despite the identification of the modality, timing and intensity of dialysis, membrane biocompatibility, hollow fiber and catheter properties as potential modifying factors, there is little convincing evidence for the superiority of one over the other. However, the available data suggest that the early initiation of RRT may be beneficial. A focused review of clinical trials and meta-analysis of clinical trials of RRT is provided.
