Acute exacerbation of bronchial asthma

 

Acute Exacerbation of Asthma (Pediatrics)

Management of an acute asthma exacerbation is time-sensitive. Rapid assessment of severity is required to initiate appropriate escalation of care.


1. Assessment of Severity

Feature Mild/Moderate Severe/Life-Threatening
Breathlessness Speaks in phrases Speaks in words; silent chest
Mental Status Agitated Confused/Drowsy
Oxygen Saturation 90–95% < 90%

2. Management Protocol (The “AIM” approach)

  • A – Airway/Oxygen: Titrate oxygen to maintain SpO2 >94%.
  • I – Inhaled Bronchodilators: Rapid-acting $beta_2$-agonists (Salbutamol) via nebulization or MDI with a spacer. Consider Ipratropium Bromide for moderate/severe cases (SABA + SAMA combination).
  • M – Methylprednisolone/Systemic Steroids: Administer early (oral or IV) to reduce airway inflammation.

3. High-Yield Clinical Pearls

  • Silent Chest: A clinical red flag indicating poor air entry; it does not mean the child is getting better—it means they are exhausted.
  • Magnesium Sulfate: Consider IV Magnesium Sulfate for severe, refractory exacerbations.
  • Antibiotics: Not indicated for viral-induced asthma; reserve only for strong evidence of bacterial pneumonia.

NEET PG Hint: Remember: Ipratropium Bromide (SAMA) is only added to SABA in the first hour of management for moderate-to-severe exacerbations; it is not indicated for chronic maintenance. For more high-yield protocols and free medical questions, visit mymedschool.org.
