Which therapy is commonly used for pediatric stridor according to these protocols?

• A. Nebulized Epinephrine
• B. Nitro
• C. Ketorolac
• D. CPAP

Answer: (A)

Nebulized epinephrine is used because it quickly reduces airway swelling by causing vasoconstriction in the mucosa of the upper airway, which opens the airway and relieves stridor within minutes. This rapid, targeted effect buys time for other treatments (like steroids) to work and stabilizes the child during a croup-style airway obstruction. The other options don’t address the swollen airway tissue directly. Nitroglycerin is for cardiac-related chest pain and doesn’t treat airway edema. Ketorolac is an analgesic/anti-inflammatory with no role in rapidly reducing airway swelling. CPAP can help in some types of respiratory distress, but it’s not the standard, first-line therapy for pediatric stridor from croup and can be inappropriate in certain cases.
