Conventional continuous extracorporeal treatments such as hemofiltration and hemodiafiltration have not achieved significant reduction in cytokine plasma levels, in spite of their increasing popularity mainly related to the unnecessary fluid restriction thereby rendering adequate caloric intake possible (Actualités Nephrologiques, 1994). This is mainly due to reduced filtration, to saturability of the adsorption-related phenomena and to the absence of a convective mass transfer. New approaches have been more recently introduced. The concept of blood purification has been amplied in some new innovative techniques that use non-selective or selective sorbents. We will focus on the criteria used by others and us to assess the efficiency in vitro and in animal models of sepsis of more recently introduced non-selective and selective devices. Among the innovative techniques, modalities aimed at the plasma treatment will receive emphasis. These modalities that are based on plasma filtration with the use of different sorbents. The preliminary results obtained from ongoing clinical trials will be presented. We will also expand on the technical, biological and clinical aspects that should be addressed in order to establish a new modality as innovative in the treatment of sepsis.
