Maintenance hemodialysis is one of the renal replacement therapy that end-stage renal disease patients mainly rely on. Dyskalemia is one of the most common metabolic complications in patients undergoing maintenance hemodialysis. Both pre-dialysis hyperkalemia and hypokalemia during and after dialysis may contribute to a higher risk of all-cause mortality, cardiovascular mortality in hemodialysis patients. The impact of serum potassium fluctuation has attracted widespread attention in recent years. Due to the intermittent nature of maintenance hemodialysis, patients are prone to frequent fluctuations of serum potassium. Potassium variability may be a better indicator to reflect potassium homeostasis, and large variability of potassiun is recognized as a potential risk factor for poor outcomes. In addition, the rapid fluctuation of serum potassium concentration during hemodialysis may increase the risk of malignant arrhythmia, sudden cardiac death and other poor outcomes. The gradient of serum and dialysate potassium is an important factor that influence the removal of potassium, which is also affected by other dialysate components. Therefore, strengthening the monitoring and management of serum potassium, selecting appropriate dialysate potassium concentration and individualizing dialysate prescription may be beneficial to maintain potassium homeostasis, reduce dyskalemia and improve prognosis. This review briefly expounds the feature of serum potassium level and discusses its effect on outcomes in patients with maintenance hemodialysis, emphasizing the relevance of potassium variation and prognosis in patients with maintenance hemodialysis and the impact of dialysate composition on potassium homeostasis.

MHD患者心血管不良事件和猝死的发生风险显著增加,血液透析患者中约55.0%因心脏疾病死亡,其中因心律失常/心脏骤停(或心源性猝死)死亡的患者占44.9%[16]。透析预后和实践模式研究(dialysis outcomes and practice study,DOPPS)5期研究结果显示,我国MHD患者有7.3%死于心脏骤停,3.3%死于心律失常[17]。高钾血症、透析期间和透析结束时低钾血症均为MHD患者发生心律失常导致死亡的重要因素。
