• A 52-year-old man receiving long-term hemodialysis and a β-adrenergic blocker for hypertension had symptoms of acute bronchospasm when exposed to a new hemodialyzer. Resistant to two doses of subcutaneous epinephrine (1 mL of 1:1000 dilution) and one intravenous dose of aminophylline (250 mg), the bronchospasm was rapidly relieved by metaproterenol sulfate given by inhalation one hour later.
