Effect of Low Versus High Dialysate Sodium Concentration on Blood Pressure and Endothelial-Derived Vasoregulators During Hemodialysis: A Randomized Crossover Study

Low dialysate sodium concentrations significantly decreased systolic BP and ameliorated intradialytic hypertension. Longer studies are needed to determine the long-term effects of low dialysate sodium concentrations on BP and clinical outcomes.
