We experienced the anesthetic management of coronary artery bypass graft operation (3 vessels) in a patient with hypothyroidism. Prior to the operation, the substitution therapy for thyroid hormone was performed, but thyroid function could not be normalized. From 30 minutes after starting cardiopulmonary bypass, edema appeared on four limbs. Also, edema of intestinal tract and the distended abdomen was observed. By administering T4 preparation intravenously edema diminished within about 2 hours without exhibiting any change in ECG findings and hemodynamics. This case may suggest that the intraoperative substitution of thyroid hormone is a safe and effective method in a patient with hypothyroidism.
