In view of the results obtained, we decided to incorporate the technique to our Unit. We have indicated AFB-K in 27 patients who have been on dialysis for up to 5 years with the

We concluded that patients with arrhythmia or at risk of suffering arrhythmia benefited from potassium profiled dialysis, particularly those subjects with hyperkalaemia. Larger studies are required to confirm this reduction in arrhythmias, which could imply improved

Based on the literature reviewed, AFB-K is seen to be a dialysis technique offering the possibility of modulating potassium reduction according to the needs of each individual patient, with a view to ensuring slower reductions and thus preventing the appearance of

One of the advantages afforded by this technology is the possibility of individualising the prescription of dialysis with a view to improving patient tolerability and prognosis (Phipps et al., 2010). Potassium profiling of the dialysate with AFB-K allows us to advance in this direction. The reduction of arrhythmias and the improved haemodynamic stability can contribute to improve the cardiovascular prognosis and survival of the patients. Larger studies (which are also more difficult to carry out) are needed to confirm improved patient survival with the new, attractive dialysis techniques.
