A patient with history of hypothyroidism is admitted with severe confusion and nonpitting edema.

The patient has signs of myxedema coma, a life-threatening complication of hypothyroidism. The patient needs immediate treatment with thyroid hormone replacement, glucocorticoids, and supportive care. One of the supportive measures is to correct the hypothermia that often accompanies myxedema coma. A forced air warming blanket is a device that delivers warm air through a hose to a blanket that covers the patient. This helps to raise the patient’s core temperature and prevent further complications. Insulin drip is not indicated, as the patient does not have diabetes or hyperglycemia. 3% saline is a hypertonic solution that can worsen the hyponatremia and fluid overload that are common in myxedema coma. Diuretics are not recommended, as they can cause dehydration and electrolyte imbalance in the patient.
