Which agent is contraindicated in asthmatics?

• A. A Desflurane
• B. B Sevoflurane
• C. C Isoflurane
• D. D Halothane

Answer: (A)

Desflurane is avoided in asthmatics because it is a pungent, airway-irritating volatile anesthetic. Its rapid onset and high concentration can trigger coughing, laryngospasm, and bronchospasm, which are dangerous for reactive airways. In contrast, sevoflurane is non-irritating and commonly preferred for patients with asthma due to smoother induction and less bronchial reactivity. Isoflurane and halothane have their own drawbacks, but the key reason desflurane is contraindicated is its potential to provoke airway irritation and bronchospasm in asthmatic patients.
