There is usually no effective treatment for hyperkalemia. Hyperkalemia may be caused by excessive input of potassium-containing drugs, decreased renal excretion of potassium, or triggered by other diseases. Attention needs to be paid to avoiding triggers, medication, and controlling the primary disease. Patients need to stop potassium salt intake in time after hyperkalemia occurs, and not to take potassium-containing drugs, such as potassium chloride tablets, potassium citrate granules, etc., to avoid the aggravation of hyperkalemia. Patients with hyperkalemia also need to inject hypertonic glucose solution, insulin injection and other drugs in time, which can promote potassium to enter the cells, help potassium metabolism in the body, and effectively improve the symptoms caused by hyperkalemia. In addition, it is also necessary to actively treat the primary disease, such as severe infection, shock, burns, tumors, and renal failure, which cause a decrease in potassium excretion. For these primary diseases or triggers, potassium-lowering treatment can be carried out by actively controlling the primary diseases and on the basis of primary disease control. Severe hyperkalemia may also require hemodialysis.
