Removal of blood solutes in patients with decreased or absent glomerular filtration is the prime objective of continuous renal replacement therapies (CRRTs). However, because these blood solutes are of different molecular weights, factors such as the porosity and hydrophobicity of the filter membranes and the extracorporeal flow rates determine the CRRT that is the most effective filtration system. This article discusses both small and large solute removal, the interaction of convection and diffusion, and the potential for CRRTs to remove particular inflammatory mediators of acute renal failure.

Abstract
Removal of blood solutes in patients with decreased or absent glomerular filtration is the prime objective of continuous renal replacement therapies (CRRTs). However, because these blood solutes are of different molecular weights, factors such as the porosity and hydrophobicity of the filter membranes and the extracorporeal flow rates determine the CRRT that is the most effective filtration system. This article discusses both small and large solute removal, the interaction of convection and diffusion, and the potential for CRRTs to remove particular inflammatory mediators of acute renal failure.File in questo prodotto:
