Drugs for treating high potassium in uremia include calcium polystyrene sulfonate, calcium gluconate, sodium bicarbonate, hypertonic glucose + insulin, furosemide and other drugs. 1. Drugs for lowering blood potassium: hypertonic glucose solution plus insulin can be chosen, in addition to cation exchange resin, such as calcium polystyrene sulfonate bulk, sodium zirconium cyclosilicate, etc. Meanwhile, sodium bicarbonate injection and diuretics (furosemide, etc.) can be used to promote the excretion of potassium ions or their transfer into the cells. 2. Emergency counteracting of arrhythmia: calcium gluconate can be pushed intravenously slowly, and repeated injections can be chosen if necessary, to antagonize the toxic effect of high potassium on the heart, and at the same time promote the transfer of potassium ions into the cells, thus assisting in lowering potassium. The above medications should be used in accordance with medical advice. Uremic patients with high potassium are recommended to consult regular hospitals and receive standardized treatment under the guidance of physicians.
