Rare in children Extremely high fat diet or starvation causes ketosis with normo-glycemia The abdominal pain associated with ketoacidosis may suggest a surgical abdomen especially appendicitis Treatment Principles of therapy in ketoacidosis restore fluid volume inhibit lipolysis restore normal glucose utilization using insulin correct total body sodium and potassium depletion correct acidosis prevent or treat cerebral edema Ketonemia without acidosis give 10-20 of total daily insulin dose subcutaneously H NL or regular insulin every 2-3 hours with oral fluids until ketonuria resolves Caution must be exercised in treating fluid deficits in diabetic ketoacidosis to avoid hyponatremia and cerebral edema Pearl Hypocalcemia can occur during treatment of diabetic ketoacidosis if all IVpotassium is given as potassium phosphate. Hypophosphatemia results if no potassium phosphate is given. Use 50 potassium chloride or acetate and 50 potassium phosphate. 10 This page intentionally left blank -------11------------ Inborn Errors of Metabolism Glycogen
