Review of the mechanism and nutrition recommendations for patients undergoing continuous renal replacement therapy

Abstract

Continuous renal replacement therapy (CRRT) is a common treatment modality in the intensive care unit for patients with acute kidney injury requiring renal replacement therapy. It offers hemodynamic stability while maintaining excellent control of solute and extracellular fluid. To those outside of nephrology, continuous dialysis is often a confusing and poorly understood form of renal replacement therapy. This review aims to provide an overview of CRRT as well as address some of the nutrition concerns surrounding this complex group of patients.
