Diabetic ketoacidosis-induced hyperkalemia. Prevalence and possible origin.
We report the biochemical data of 22 hospital admissions because of untreated diabetic ketoacidosis. Fifty percent of admitted patients showed an initial serum potassium between 4.6 and 6.0 mEq/l whereas severe hyperkalemia (value greater than 6.1 mEq/l) occurred in 32%. Initial potassium levels show a slight negative correlation with pH but a stronger correlation (p less than 0.001) was found between the initial serum potassium and glucose values. We suggest that hyperglycemia due to insulinopenia must be one of the factors in the pathogenesis of this hyperkalemia.
