Pediatric Emergencies
When a child is gasping for air, every second feels eternal — for the family and for the doctor. Recognizing respiratory distress early can mean the difference between panic and prevention.
🫁 Understanding Respiratory Distress
Definition
Respiratory distress is when a child struggles to breathe effectively due to impaired oxygenation or ventilation — often seen as increased work of breathing.
👀 How to Recognize It — The “Look, Listen, Feel” Rule
Look
- Nasal flaring
- Chest indrawing (subcostal, intercostal, suprasternal retractions)
- Use of accessory muscles
- Cyanosis (especially lips, tongue, nail beds)
- Restlessness or anxiety, or lethargy
Listen
- Grunting
- Wheezing (musical sound on expiration)
- Stridor (inspiratory noise)
- Crackles
Feel
- Rapid pulse and respiratory rate
- Temperature (infection?)
- Chest expansion symmetry
🧠 Common Causes of Respiratory Distress
| Age Group | Common Causes |
|---|---|
| Neonate | RDS, pneumonia, congenital heart disease |
| Infant | Bronchiolitis, pneumonia |
| Toddler/Child | Asthma, foreign body aspiration, pneumonia |
| Any age | Sepsis, anaphylaxis, trauma |
💡 Mnemonic: “A-P-B-F” — Asthma, Pneumonia, Bronchiolitis, Foreign body.
⚠️ Severity Signs (When It’s Getting Dangerous)
- Inability to talk or feed
- Exhaustion or altered consciousness
- Grunting, head bobbing
- Silent chest (ominous in asthma)
- Cyanosis or SpO₂ < 90% despite oxygen
🚨 These call for immediate intervention!
🌪️ Asthma Attack in Children
What Happens During an Attack
In an acute asthma attack:
- Bronchospasm → airway narrowing
- Mucosal edema → more narrowing
- Mucus plugging → airflow obstruction
Result: the child can’t exhale effectively → air trapping and hyperinflation → hypoxia.
Clinical Features
| Mild–Moderate Attack | Severe Attack | Imminent Respiratory Failure |
|---|---|---|
| Breathlessness, able to talk | Too breathless to talk/feed | Silent chest, cyanosis |
| RR mildly increased | RR > 50/min | Exhaustion, confusion |
| Wheeze present | Loud or widespread wheeze | No wheeze (air entry minimal) |
| SpO₂ ≥ 92% | SpO₂ < 92% | SpO₂ < 88% |
💡 Silent chest + drowsiness = impending arrest.
💊 Emergency Management — The “ABC S A M” Steps
| Step | Action | Drugs / Notes |
|---|---|---|
| O – Oxygen | Give high-flow O₂ (5–10 L/min) | Maintain SpO₂ ≥ 94% |
| S – SABA | Short-acting β₂ agonist (Salbutamol) via nebulizer | 2.5–5 mg every 20 min × 3, then as needed |
| A – Add steroids | Reduce airway inflammation | Prednisolone 1–2 mg/kg PO or Hydrocortisone 4 mg/kg IV |
| M – Monitor and escalate | Watch HR, RR, SpO₂ | If poor response → add Ipratropium + IV MgSO₄ (25–50 mg/kg) |
💉 If Severe or Not Improving
- Ipratropium bromide nebulizer 0.25–0.5 mg with each salbutamol dose.
- IV magnesium sulfate (bronchodilator effect).
- IV aminophylline or terbutaline infusion if refractory.
- Intubate and ventilate if exhaustion, hypoxia, or impending respiratory arrest.
🧘 Post-Attack Management
Recovery and Prevention
- Observe for 24 hours if severe.
- Teach inhaler technique and trigger avoidance.
- Consider long-term control: Inhaled corticosteroids (beclomethasone, budesonide); Leukotriene receptor antagonists (montelukast)
- Develop an asthma action plan for home.
💭 Distinguishing Asthma from Other Causes of Respiratory Distress
| Condition | Key Clues |
|---|---|
| Asthma | Recurrent wheeze, responds to bronchodilators |
| Bronchiolitis | <2 yrs, crackles + wheeze, viral prodrome |
| Pneumonia | Fever, cough, crepitations, asymmetric breath sounds |
| Foreign body | Sudden onset, localized wheeze, choking episode |
| Anaphylaxis | Urticaria, hypotension, stridor, facial swelling |
🧠 Quick Review: 5 Red Flags in Respiratory Distress
- Child cannot speak or cry.
- Severe chest indrawing or head bobbing.
- Cyanosis or oxygen saturation <90%.
- Altered mental status or exhaustion.
- “Silent chest” in asthma = no air entry = act now!
✨ Key Takeaways
- Early recognition of distress saves lives — watch the chest, not the monitor.
- Asthma attacks need prompt bronchodilation + steroid cover.
- Always check oxygen saturation, air entry, and response to treatment.
- Teach prevention: adherence, inhaler use, trigger control.
