Patients with diabetic ketoacidosis can be treated by oral or intravenous rehydration, insulin infusion, correction of electrolyte and acid-base balance, hemodialysis, etc. It is recommended to consult a doctor in time. 1. Oral or intravenous rehydration: patients with diabetic ketoacidosis need rehydration to expand blood volume and correct water loss, choose oral or intravenous rehydration according to the severity of the disease. 2. Infusion of insulin: diabetic ketoacidosis can be supplemented with small doses of insulin, which has an inhibitory effect on ketone body production, eliminating ketone bodies and lowering blood glucose. 3. Correct electrolyte and acid-base balance: patients with diabetic ketoacidosis and low potassium need to supplement potassium, and severe acidosis need to supplement sodium bicarbonate, so as to correct the electrolyte and acid-base balance in the body. 4. Hemodialysis: Patients with diabetic ketoacidosis who have epilepsy, cardiac arrhythmia, acute renal failure and other symptoms can be treated by hemodialysis to remove toxic metabolites in the blood and maintain the stability of the internal environment of the body. Patients with diabetic ketoacidosis should immediately go to the hospital for treatment under the guidance of a doctor to avoid delay.
