Drowsiness in diabetic patients should be alert to ketoacidosis, hyperosmolar hyperglycemia syndrome, etc., and should seek medical attention in time, under the guidance of the doctor to lower blood glucose, replenish fluids, correct electrolyte and acid-base balance imbalance, and deal with triggers and complications. Drowsiness in diabetic patients should be alert to neuropsychiatric changes. Acute infection, trauma, etc. can easily induce diabetic patients to develop ketoacidosis (DKA), hyperosmolar hyperglycemia syndrome and other acute serious metabolic disorders, which can be manifested in different degrees of consciousness disorders, such as drowsiness or even coma, etc., and the condition is critical, and should be treated in time. 1. Hypoglycemic treatment: small-dose insulin can be injected intravenously to stabilize the blood glucose level as soon as possible. 2. Rehydration therapy: rehydration is the key to treat DKA and hyperosmolar hyperglycemia syndrome, which can improve effective tissue perfusion, relieve acidosis and prevent shock. 3. Correct electrolyte and acid-base balance imbalance: patients often have metabolic acidosis, if acidosis is more serious (blood PH <7.1), alkaline supplementation therapy (such as sodium bicarbonate infusion). 4. Treatment of triggers and complications: infected patients should be treated with sensitive antibiotics for anti-infection; traumatized patients should be actively treated for trauma; prevention and treatment of renal failure and cerebral edema. There are many reasons for diabetic patients to have drowsiness, they should consult the doctor in time for early treatment and follow the doctor's instructions for medication.
