Summary

Usually, hyperglycaemia crisis presents with acidotic pH, but ketoalkalosis is a rare and unheard entity presenting in diabetic ketoacidosis. We describe three unique cases where the patients present with hyperglycaemia >250 mg/dL, normal or alkalotic pH, and bicarbonate >20 meq/L, which does not meet criteria for diabetic ketoacidosis. However, once these patients were supplemented with intravenous fluids, diagnosis of diabetic ketoacidosis was evident in laboratory analysis. These case series provide a learning opportunity in diagnosing and management of this rare phenomenon.
