Abstract：Objective To investigate the effect of dialysate potassium concentration on the serum potassium and arrhythmia during hemodialysis(HD) in patients with end-stage renal disease (ESRD). Methods Fifty ure-mia patients undergoing maintenance hemodialysis were treated by dialysate of different concentrations of potassium ion in two periods of three months. Potassium ion concentration in the first period was 2.0 mmol/L, and 3.0 mmol/.L in the second period. Clinical symptoms, serum potassium and electrocardiogram before and after hemodialysis were recorded and observed. Results The serum K + in B group was significantly higher than that in B group(P <0.05 ). The incidences of arrhythmia in B group decreased (P < 0.05 ). There was no significant difference of hy-perkalemia between the two different HD treatments (P > 0.05 ). Conclusion The potassium density of 3.0 mmol/L dialysate can avoid or decrease the occurrence of cardiac arrhythmia during dialysis. It is valid and safe for preven-ting cardiac arrhythmia when patients have hemodialysis three times a week.
