高钾血症是维持性血液透析患者常见的并发症之一,血清钾的浓度>5.5 mmol/L即为高钾血症,维持性血液透析患者中有10%发生过高钾血症~([1])。高钾血症对机体的影响主要表现在心肌和骨骼肌毒性,血钾>6.5 mmol/L就会对心脏有抑制作用,导致心脏骤停。钾的来源主要是食物,90%的钾靠肾脏排泄,维持性血液透析患者肾脏功能丧失,高钾饮食
Hyperkalemia is one of the common complication of maintenance hemodialysis patients, serum potassium concentration> 5.5 mmol / L is hyperkalemia, 10% of maintenance hemodialysis patients have hyperkalemia ~ ( [1]). Hyperkalemia on the body mainly in myocardial and skeletal muscle toxicity, potassium potassium> 6.5 mmol / L will have an inhibitory effect on the heart, leading to cardiac arrest. The main source of potassium is food, 90% of potassium excretion by the kidneys, renal function loss in patients with maintenance hemodialysis, high potassium diet
