Question:medium
The anaesthetic gas with maximum respiratory irritation is:
The anaesthetic gas with maximum respiratory irritation is:
Show Hint
Sevoflurane is used for gas induction because it is non-pungent; the opposite extreme is your answer.
Updated On: Jun 23, 2026
- Halothane
- Enflurane
- Desflurane
- Sevoflurane
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Rank the volatiles by smell and airway tolerance. Pungency drives coughing, breath holding and laryngospasm on induction.
Step 2: Sevoflurane and halothane are sweet and well tolerated, which is exactly why sevoflurane is used to gas-induce children.
Step 3: At the other extreme, desflurane has a sharp, ethereal pungency and the highest airway irritancy of the group, making it unsuitable for inhalational induction.
Step 4: Maximum respiratory irritation therefore points to desflurane.
\[\boxed{\text{Desflurane}}\]
