Diabetic ketoacidosis in the pediatric emergency department.

Despite many advances, the incidence of pediatric-onset diabetes and diabetic ketoacidosis (DKA) is increasing. Diabetes mellitus is 1 of the most common chronic pediatric illnesses and, along with DKA, is associated with significant cost and morbidity. DKA is a complicated metabolic state hallmarked by dehydration and electrolyte disturbances. Treatment involves fluid resuscitation with insulin and electrolyte replacement under constant monitoring for cerebral edema. When DKA is recognized and treated immediately, the prognosis is excellent. However, when a patient has prolonged or multiple courses of DKA or if DKA is complicated by cerebral edema, the results can be devastating.
