Management of Acute Bronchitis in Pediatric Patients
Acute bronchitis in children requires immediate clarification because the term encompasses two fundamentally different diseases—acute viral bronchiolitis (infants <2 years) and protracted bacterial bronchitis (older children with chronic wet cough)—each requiring completely opposite management approaches. 1, 2, 3
Acute Viral Bronchiolitis (Infants 1-23 Months)
Diagnosis
- Diagnose based on clinical presentation alone: rhinitis, cough progressing to tachypnea, wheezing, rales, and increased work of breathing. 4, 1, 2
- Do not routinely order chest radiographs, viral testing, or laboratory studies—these do not change management and increase costs unnecessarily. 4, 1, 2, 5, 6, 7
Treatment: Supportive Care ONLY
The cornerstone of management is supportive care alone—no pharmacologic interventions are routinely recommended. 4, 1, 2, 3
Oxygen Management
- Administer supplemental oxygen only if SpO2 persistently falls below 90%; maintain SpO2 ≥90% with standard oxygen delivery. 4, 1, 2, 3, 6
- Discontinue oxygen when SpO2 ≥90%, infant feeds well, and has minimal respiratory distress. 4
- Infants with hemodynamically significant heart/lung disease and premature infants require close monitoring during oxygen weaning. 4
Hydration and Nutrition
- Assess ability to take fluids orally; use IV or nasogastric fluids only when oral intake is inadequate. 4, 3, 6
- Continue breastfeeding if possible—breastfed infants have 72% reduced hospitalization risk. 1, 3
- Feeding difficulties increase significantly when respiratory rate exceeds 60-70 breaths/minute due to aspiration risk. 2
Airway Clearance
- Use gentle nasal suctioning only as needed for symptomatic relief; avoid deep suctioning as it is associated with longer hospital stays. 3
What NOT to Use
Do not routinely use any of the following—they lack evidence of benefit: 4, 1, 2, 3
Bronchodilators (albuterol, beta-2-agonists): Not recommended routinely. 4, 5, 6, 7
- A carefully monitored trial may be considered as an option, but continue only if documented positive clinical response using objective evaluation. 4
Corticosteroids: Do not use routinely—no evidence of benefit. 4, 5, 6, 7
Antibiotics: Use only with specific indications of bacterial coinfection (risk of serious bacterial infection is <1%). 4, 2, 5, 6
- Fever alone does not justify antibiotics. 2
Nebulized epinephrine or hypertonic saline: Not recommended routinely. 6, 7
Risk Stratification
High-risk infants requiring closer monitoring include: 4, 2, 3
- Age <12 weeks
- History of prematurity (<35 weeks gestation)
- Hemodynamically significant congenital heart disease
- Chronic lung disease of prematurity
- Immunodeficiency
Hospitalization criteria: 3
- SpO2 <90% persistently
- Moderate to severe respiratory distress
- Inability to feed or signs of dehydration
- Apnea
Protracted Bacterial Bronchitis (Chronic Wet Cough >4 Weeks)
This is a completely different disease requiring antibiotic therapy, not supportive care. 3
- Use amoxicillin-clavulanate as first-line antibiotic for 2 weeks initially, targeting common respiratory bacteria (Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis). 4, 3
- Extend treatment up to 4 weeks if needed. 3
- Early identification and treatment prevents bronchiectasis development—children who don't respond to initial treatment have a 5.9-fold increased likelihood of CT-diagnosed bronchiectasis. 3
Chronic Cough Post-Bronchiolitis (>4 Weeks After Acute Episode)
- Manage according to pediatric chronic cough guidelines: evaluate for cough pointers and use 2 weeks of antibiotics for wet/productive cough without specific pointers (e.g., coughing with feeding, digital clubbing). 4, 2
- Do not use asthma medications unless other evidence of asthma is present (recurrent wheeze and/or dyspnea). 4
- Do not use inhaled osmotic agents (hypertonic saline, mannitol). 4
Prevention Strategies
- Palivizumab prophylaxis for high-risk infants: 5 monthly doses (15 mg/kg IM) starting November/December for infants with prematurity <35 weeks, hemodynamically significant heart disease, or chronic lung disease. 4, 1, 3
- Promote breastfeeding—reduces hospitalization risk by 72%. 4, 1, 3
- Avoid tobacco smoke exposure—strong recommendation. 4, 1, 3
- Hand decontamination with alcohol-based rubs is the most important step in preventing nosocomial RSV spread. 4
Critical Pitfalls to Avoid
- Do not treat based solely on pulse oximetry readings without clinical correlation—transient desaturations occur in healthy infants. 2
- Do not apply pediatric bronchiolitis treatment paradigms to adults—adult bronchiolitis is fundamentally different and requires cause-specific treatment. 2
- Do not overlook the distinction between acute viral bronchiolitis and protracted bacterial bronchitis—one requires supportive care only, the other requires antibiotics. 1, 2, 3
