Review: modelling the dialysate

Abstract

Dialysate prescription is evolving as new technology allows greater opportunity to alter dialysate constituents throughout dialysis, providing scope for tailored prescription for an individual patient. The intention of modelling or profiling is to improve the tolerability of dialysis and long-term patient outcomes. This approach can be applied to both electrolytes and water. Despite these advances in technology, benefits of modelling have not been demonstrated consistently. This review examines the use of individual prescription and modelling of dialysate sodium, ultrafiltrate, potassium, calcium, magnesium, bicarbonate and phosphate.
