It is often necessary to have a small animal model for hyperkalemia for use in electrolyte and acid base experiments. In reviewing the literature, we found a paucity of such animal models, especially for acute hyperkalemia. We have had difficulty in inducing acute hyperkalemia in rats using potassium chloride alone either intravenously or intraperitoneally and felt the need for an easily reproducible small animal model for hyperkalemia. We gave experimental animals a combination of intraperitoneal amiloride 3 mg/kg and potassium chloride 2 meq/kg in two divided doses while control animals received only the potassium chloride. Initial serum potassiums were similar but at 2 hr, the experimental group had significantly higher serum potassium levels which were sustained throughout the 8 hr of the experiment. Arterial blood gas revealed no significant difference in blood pH values at all time points during the experiment. We conclude that the combination of amiloride and potassium chloride is useful to produce acute hyperkalemia in rats and that this hyperkalemia is sustained beyond 6 hr. This model is convenient for use in metabolic experiments requiring the use of acutely hyperkalemic rats.
