Changing acute renal failure treatment from intermittent hemodialysis to continuous hemofiltration: Impact on azotemic control

Abstract

Background. Continuous renal replacement therapy is increasingly used in the management of acute renal failure in critically ill patients. The advantages of continuous renal replacement therapy (CRRT) over intermittent hemodialysis (IHD), however, are not yet fully documented. In particular, it is unknown whether continuous veno-venuous hemodiafiltration (CVVHDF) provides better control of azotemia than IHD. Objectives. To study the effect on azotemic control of changing acute renal failure treatment from IHD to CVVHDF. Settings. Tertiary intensive care unit. Patients. Forty seven consecutive critically ill patients with multiorgan failure and acute renal failure treated with IHD and 47 simi..
