**Question:** A 4 yr old child has 'seal barking' like croupy cough. Management includes A/E -

A. Oxygen therapy
B. Inhalation therapy with nebulized salbutamol
C. Inhalation therapy with nebulized adrenaline
D. Oxygen saturation monitoring

**Core Concept:** Seal barking cough is a characteristic, croupy cough in children, typically seen in viral upper respiratory tract infections like respiratory syncytial virus (RSV) infection. Croup is a respiratory emergency often requiring emergency department (A/E) management.

**Why the Correct Answer is Right:** The seal barking cough is managed in the emergency department (A/E) because it is a severe respiratory distress caused by airway inflammation and narrowing. In this context, nebulized salbutamol is the correct choice. Salbutamol is a beta-agonist bronchodilator that relaxes smooth muscles of the airways, dilating the airways and improving oxygenation.

**Why Each Wrong Option is Incorrect:**

A. Oxygen therapy is important in respiratory distress, but nebulized salbutamol is the treatment for the airway inflammation causing the respiratory distress.

B. Nebulized adrenaline (epinephrine) is a vasoconstrictor that would worsen airway inflammation and narrowing, not improve it.

C. Nebulized adrenaline (epinephrine) is not indicated in this context, as it is a vasoconstrictor that would aggravate airway inflammation and narrowing, not alleviate it.

D. Oxygen saturation monitoring is important in respiratory distress, but nebulized salbutamol is the treatment for the airway inflammation causing the respiratory distress.

**Clinical Pearl:** Croup is a common pediatric respiratory emergency caused by viral infections like respiratory syncytial virus (RSV). It presents with a characteristic seal barking cough and can cause severe respiratory distress. The appropriate management involves nebulized salbutamol to alleviate airway inflammation and narrowing.
