Standard intermittent hemodialysis (IHD) used for the treatment of acute renal failure (ARF) at an intensive care unit has significant biochemical and physiological drawbacks. In the past 20 years, these drawbacks have stimulated the development of continuous renal replacement therapy (CRRT) and its ever-increasing use. However, CRRT is technically complicated and requires 24-hour monitoring. In some clinics, the use of CRRT leads to that each patient is under his/her nurse's surveillance, instead 1 nurse per 2 patients as before; this change has economic consequences and may limit nursing accessibility to other patients. The procedures prolonging intermittent therapy do not require 24-hour monitoring may benefit the treatment of ARF at the intensive care therapy. In this paper the authors call such procedures for continuous intermittent renal replacement therapy. They are characterized by a number of basic principles: (1) the use of modified or standard dialysis apparatuses; (2) the application of diffuse, convection, or both; (3) a certain reduction in the rate of elimination of dissolved substances as compared with IHD; (4) more prolonged treatment: above usual 3 or 4 hours of IHD, but not more than 8-12 hours (hence the term "intermittent"); (5) the use of on-line generation dialysate or substituting fluid. Information on the effectiveness and safety of this procedure is being now compiled.
