Summary Fifty‐seven patients had arterial hypotension induced by a technique with halothane and sodium nitroprusside during operations on the ear, nose and parotid gland. Metoprolol, a cardioselective beta‐adrenergic blocker, was used when required to maintain the pulse rate at 80 beats per minute or less and to assist in reducing the blood pressure. Metoprolol was used in 50 cases while 7 cases remained at a pulse rate of less than 80 bpm spontaneously.
