Isoflurane is known for which characteristic among inhaled anesthetics?

• A. Sevoflurane is pungent
• B. Isoflurane has a pungent odor and is rarely used for induction
• C. Desflurane is non-pungent
• D. Nitrous oxide has a pungent odor

Answer: (B)

Pungency and airway irritation influence how inhaled anesthetics are used for induction. Isoflurane has a pungent odor that irritates the airways, making induction with this agent uncomfortable and less reliable due to coughing or bronchospasm. Because of this irritation, it is rarely chosen to start anesthesia by inhalation; it’s more commonly used for maintenance after induction with another agent. In contrast, sevoflurane is non-irritating and favored for inhalational induction, especially in children, while desflurane and nitrous oxide have different characteristics that don’t align with induction needs. So the statement that Isoflurane has a pungent odor and is rarely used for induction best reflects its typical use among inhaled anesthetics.
