The use of cardioselective β-blockers in a patient with idiopathic hypertrophic subaortic stenosis and chronic obstructive pulmonary disease

The -adrenergic receptor blocking drugs are commonly used in the treatment of patients with idiopathic hypertropic subaortic stenosis (IHSS). These drugs, however, are contraindicated in patients with chronic obstructive pulmonary disease (COPD). We report the anesthetic management of a patient with IHSS complicated by severe COPD. We concluded that the 1 selective, ultra-short acting -blocker, esmolol, can be used intraoperatively when both conditions are present. The pathophysiology and the commonly used anesthetic drugs and practices for treatment of patients with IHSS are reviewed. © 2003 by Elsevier Science Inc.
