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.
