Show Answer

Correct Answer » D
Explanation
|
|
Desflurane is the most pungent volatile anesthetic. It causes marked airway irritation, coughing, and sympathetic stimulation. Therefore, it is not used for inhalational induction.
Pungency of volatile anesthetics determines airway irritation. More pungent agents cause coughing, breath-holding, and laryngospasm, and are not suitable for inhalational induction.
Order of pungency:
Desflurane > Isoflurane >> Sevoflurane (least pungent)
