Pathogenesis, diagnosis and treatment of diabetic ketoacidosis.

The diagnosis of diabetic ketoacidosis must be suspected and the initiation of treatment should be prompt to provide a satisfactory outcome in the treatment of diabetic ketoacidosis. Corrections of fluid and electrolyte deficiencies should be made slowly; rapid "push"injections or large infusions of sodium bicarbonate should avoided and ample amounts of potassium should be given early. Precautions should be taken so that blood glucose concentrations do not fall rapidly, and so that blood glucose levels of 250-300 mg/100 ml are maintained by the administration of 5-10% glucose solutions. Bicarbonate therapy is indicated only in severe acidosis (pH less than or equal to 7.1). Physicians who are trained in the care of diabetes mellitus should supervise the treatment. In our hospital the same staff physicians and fellows attend all patients with diabetes. In addition the efforts of our house staff and nurses have contributed significantly to the care of these patients.
