Anaesthetic gas with maximum respiratory irritation: (A) Desflurane, (B) Sevoflurane, (C) Enflurane, (D) Halothane
Answer is A. * Desflurane, unlike halothane or sevoflurane has a pungent smell which makes it unpleasant for inhalational induction. * When more than 6% desflurane is used, the pungency produces salivation, airway irritation, breath holding and coughing.
