The HFR Aequilibrium^® dialysis technique is a form of endogenous haemodiafiltration that lets the patient be reinfused with the ultrafiltered liquid. A double-chamber dialyser is used which makes it possible to separate the convective process from the diffusive process, plus a resin cartridge that basically captures the β₂ microglobulin and the angiogenin but not Ca⁺⁺, Mg⁺⁺, HCO₃, essential amino acids, albumin, glucose, or phosphates, which makes it possible to recover abundant physiological substances. Software with a mathematical model and a sensor handles the extraction of sodium automatically, modifying the total conductivity throughout the dialysis. The aim of this study is to describe the results obtained on applying this technique. We carried out a descriptive transversal study from January to December 2008. Values were determined at the beginning and at the end of the study of the haemodynamic profile, haematological profile, as well as cholesterol, CRP, albumin, calcium and phosphorus. Incidents, symptomatology and interventions recorded by nursing staff were taken into account. The results show an adjustment of sodium, potassium, calcium and a tendency to stabilize in phosphorus. There was an important reduction in triglycerides compared to a slight increase in total proteins and albumin, the CRP also fell. On the other hand, as the treatment advanced, the values of haemoglobin increased. Intradialytic symptomatology decreased progressively. Accordingly, this technique involves an increase in purifying functions, with an improvement in the tolerance of the dialysis treatment.
