What is the recommended management for nasal congestion in infants?

Management of Nasal Congestion in Infants

Saline nasal irrigation is the first-line treatment for nasal congestion in infants, as it is completely safe with no cardiovascular effects while providing modest benefit for symptom relief by clearing mucus and moisturizing nasal passages. 1

Causes of Nasal Congestion in Infants

• Viral upper respiratory infections (most common)
• Neonatal rhinitis
• Anatomical issues (e.g., choanal atresia)
• Adenoidal hypertrophy
• Possible milk/soy allergies (though rare)
• Congenital masses

First-Line Management

Saline Nasal Irrigation

• Buffered saline solution (0.9% isotonic or 2.3-5% hypertonic) is effective and safe for nasal congestion in infants 1, 2
• Technique:
  • Apply saline drops to each nostril
  • Follow with gentle aspiration using a nasal bulb syringe
  • Perform before feedings and sleep to improve breathing and feeding
• Benefits:
  • Clears mucus and moisturizes nasal passages
  • Improves nasal airflow and quality of life 3
  • Helps reduce symptoms without medication risks
  • Shown to improve sleep quality and nutrition in infants with nasal congestion 2

Positioning

• Elevate the head of the crib/bassinet slightly (ensure this is done safely)
• Hold infant upright during feedings
• These measures help reduce nasal congestion through improved drainage

When to Consider Additional Interventions

For Persistent Symptoms

• If symptoms persist despite saline irrigation, consider:
  • Ensuring proper technique with saline irrigation
  • Increasing frequency of saline irrigation
  • Evaluating for possible anatomical causes

Medications to Avoid in Infants

• Intranasal decongestants: Data are insufficient to recommend oral or topical nasal decongestants for infants 3
• Antihistamines: Should not be used for primary treatment of nasal congestion in infants without evidence of allergy 3
• First-generation antihistamines: Should be avoided due to sedation and anticholinergic effects 1

Special Considerations

Nasal Congestion and Feeding

• Nasal congestion can significantly impact feeding in infants
• Clear nasal passages before feeding
• Monitor for adequate hydration and nutrition

When to Seek Medical Attention

• Signs of respiratory distress (increased work of breathing, retractions)
• Poor feeding or decreased urine output
• Fever in infants under 3 months
• Symptoms lasting more than 10 days without improvement
• Worsening symptoms after initial improvement

Emerging Research

Recent research suggests that low-dose xylometazoline (0.025%) may be safe in hospitalized infants under close monitoring 4, but this should only be considered in hospital settings under medical supervision, not as routine home care.

Prevention Strategies

• Avoid exposure to irritants (smoke, strong odors)
• Maintain optimal humidity in the infant's environment
• Breastfeeding may help reduce incidence of respiratory infections
• Minimize exposure to individuals with respiratory infections

Remember that infants under 2-6 months are obligate nasal breathers, making nasal congestion potentially more serious in this age group 3. Proper management is essential for ensuring adequate breathing, feeding, and sleep.
