Phosphatemic control during acute renal failure: intermittent hemodialysis versus continuous hemodiafiltration

Abstract

BACKGROUND: Achieving "adequacy of dialysis" includes the maintenance of normal serum phosphate concentrations and is an important therapeutic goal in the treatment of acute renal failure (ARF). It is unknown whether this goal is best achieved with intermittent or continuous renal replacement therapy. METHODS: We compared the effects of continuous veno-venous hemodiafiltration (CVVHDF) and intermittent hemodialysis (IHD) on serum phosphate concentrations using daily morning blood tests in 88 consecutive intensive care patients half of which were treated with IHD and half with CRRT RESULTS: Mean patient age was 54+/-14 years for IHD and 60+/-14 years for CVVHDF (NS). However, patients who rec..
