The practice of patients with potassium chloride poisoning is as follows: 1, Promote the lowering of blood potassium, apply calcium gluconate, which can directly counteract the high blood potassium and the effect on the polarization status of the cell membrane, so that the threshold potential can be restored to normal; 2, use sodium bicarbonate to counteract the effect of high potassium on the cell membrane in addition to promoting the entry of potassium into the cell; 3, use glucose plus insulin, insulin can prompt the cellular uptake of potassium ions, so as to make blood potassium Decrease, at the same time, the injection of calcium gluconate can prevent the emergence of hypoglycemia; 4, rapid diuresis, prompted by the kidneys to discharge; blood purification, the most effective and fastest method in hyperkalemia is blood purification; 5, with ion exchange resin, can prompt the potassium ions from the digestive tract to discharge.
