What is the management for nasal congestion in pediatric patients?

Management of Nasal Stuffiness in Pediatrics

First-Line Treatment: Saline Nasal Irrigation

Saline nasal irrigation should be the primary therapy for nasal congestion in children, as it removes debris, reduces tissue edema, and promotes drainage without risk of adverse effects. 1, 2

• Isotonic saline is more effective than hypertonic or hypotonic solutions for chronic nasal symptoms 2
• This can be combined with gentle suctioning of nostrils in infants to improve breathing 2
• Saline irrigation is recommended as initial medical management across all pediatric age groups 3

Age-Specific Medication Restrictions

Critical Safety Warnings

Oral decongestants and antihistamines must NEVER be used in children under 6 years of age due to documented fatalities and lack of proven efficacy. 2, 4

• Topical decongestants should not be used in children under 1 year due to narrow therapeutic window and risk of cardiovascular/CNS toxicity 2
• Diphenhydramine is contraindicated in children under 6 years 4
• Antihistamines should not be used for primary treatment of nasal congestion in any child, though they may help allergic symptoms in atopic patients 1

Intranasal Corticosteroids: The Most Effective Option

For children with persistent nasal congestion (>10 days), intranasal corticosteroids are the most effective medication class for controlling nasal symptoms. 1, 5

• Intranasal corticosteroids reduce inflammation around sinus ostia and encourage drainage 1
• Multiple studies in adolescents show significant symptom reduction compared to placebo 1
• These medications do NOT cause rebound congestion, unlike topical decongestants 5
• Safe for use in children aged 6 years and older when allergic rhinitis or persistent rhinosinusitis is present 1

When to Consider Antibiotics

Antibiotics should only be used when bacterial sinusitis is suspected based on specific clinical patterns, not for simple nasal congestion. 1

Three Patterns Suggesting Bacterial Sinusitis:

1. Persistent: Nasal discharge or cough for ≥10 days without improvement 1
2. Severe: Fever ≥39°C for ≥3 consecutive days with thick, colored nasal discharge 1
3. Worsening: Initial improvement followed by new fever ≥38°C or increased cough/discharge 1

• Fewer than 1 in 15 children develop true bacterial sinusitis during/after a common cold 1
• Even with persistent symptoms, observation for an additional 3 days is a reasonable alternative to immediate antibiotics 1

Medications with Insufficient Evidence

There is insufficient data to recommend oral or topical decongestants, mucolytics, or antihistamines as adjuvant therapy for nasal congestion in children. 1

• Antihistamines have limited short-term benefit (days 1-2) in adults but no clinically significant effect on nasal obstruction 1
• Decongestants may have small positive effects in adults but carry risk of rebound congestion with use >3 days 1, 5
• Nasal cromolyn is less effective than intranasal corticosteroids 1

Special Considerations for Infants

Chronic nasal congestion in infants requires evaluation for underlying causes, as neonates are obligate nasal breathers and minor obstruction can be life-threatening. 2

Key Underlying Conditions to Evaluate:

• Adenoidal hypertrophy: Most common acquired anatomic cause in infants and children 2, 6
• Gastroesophageal reflux: Causes inflammation and narrowing of posterior choanae 2
• Food allergy: Often suspected but only accounts for 0.3% of pediatric rhinitis 2

Supportive Care for Infants:

• Supported sitting position to expand lungs 2
• Adequate hydration to thin secretions 2
• Address environmental factors like tobacco smoke exposure 2
• Do NOT use chest physiotherapy - it is not beneficial 2

Common Pitfalls to Avoid

Never use topical decongestants for more than 3 days, as rebound congestion (rhinitis medicamentosa) can develop as early as day 3-4 of continuous use. 5

• If rebound congestion develops, discontinue the decongestant immediately and start intranasal corticosteroids 1, 5
• Short course (5-7 days) of oral corticosteroids may be needed for severe cases 1, 5
• When combining topical decongestants with intranasal corticosteroids from the outset, rebound can be prevented entirely 5

When to Refer to Specialist

Consultation with an allergist/immunologist is appropriate when: 1

• Prolonged manifestations of rhinitis persist
• Complications develop (otitis media, sinusitis, nasal polyps)
• Comorbid conditions exist (asthma, chronic sinusitis)
• Systemic corticosteroids have been required
• Symptoms interfere with sleep or school performance
• Treatment is ineffective or produces adverse events

Conservative Approach for Most Cases

Most children grow out of adenoid hypertrophy and recurrent colds by age 8-10 years, making conservative management the primary strategy. 6

• "Watchful waiting" is advised for rhinosinusitis in children 6
• Growth and maturation of immunological response play a major role in disease resolution 6
• Teaching proper nose-blowing and allergen avoidance should be tried before considering surgery 6
