Treatment of Bronchopneumonia in a 13-Year-Old
For a 13-year-old with bronchopneumonia (community-acquired pneumonia), amoxicillin 90 mg/kg/day divided into 2 doses is the first-line antibiotic treatment, with consideration of adding a macrolide if atypical pathogens like Mycoplasma pneumoniae are suspected. 1, 2, 3
Initial Assessment and Treatment Decision
Determine Need for Hospitalization vs. Outpatient Management
Hospitalize if any of the following are present:
- Oxygen saturation <92% 1, 2, 4
- Respiratory rate >50 breaths/min (for this age group) 2, 4
- Increased work of breathing, grunting, or respiratory distress 1, 2
- Signs of dehydration or inability to maintain oral intake 2, 4
- Altered mental status 1
Outpatient management is appropriate if:
- Oxygen saturation ≥92% on room air 2
- No respiratory distress 2
- Able to maintain adequate oral hydration 2
- Family can provide appropriate observation 2
Antibiotic Selection
For Outpatient Management (Mild-Moderate Disease)
First-line therapy:
- Amoxicillin 90 mg/kg/day divided into 2 doses for 7-10 days 2, 4
- This provides appropriate coverage for Streptococcus pneumoniae, the most common bacterial pathogen 2
Consider adding a macrolide if atypical pathogens suspected:
- Clinical clues for atypical pneumonia (Mycoplasma pneumoniae, Chlamydophila pneumoniae) include: gradual onset, prominent cough, lack of toxic appearance, and school-age presentation 5
- Azithromycin 500 mg on Day 1, then 250 mg daily on Days 2-5 3
- Alternative: Azithromycin 500 mg daily for 3 days 3
For Hospitalized Patients (Moderate-Severe Disease)
Intravenous antibiotics are indicated:
- Ampicillin or penicillin G as first-line 4
- Ceftriaxone or cefotaxime as alternatives 4
- Add vancomycin or clindamycin if MRSA suspected (necrotizing pneumonia, empyema, severe illness) 4
Supportive Care
Essential supportive measures include:
- Supplemental oxygen to maintain saturation >92% 1, 4
- Adequate hydration through oral fluids; IV fluids at 80% basal levels if unable to maintain oral intake 6, 4
- Antipyretics (acetaminophen or ibuprofen) for fever control and comfort 2
- Adequate rest 2
Do NOT use:
- Chest physiotherapy (not beneficial) 2
- Over-the-counter cough and cold medications (lack efficacy, potential harm) 2
Monitoring and Follow-Up
Expected Clinical Response
- Re-evaluate at 48-72 hours if not improving 1, 6
- Fever should begin resolving within 48 hours for typical bacterial pneumonia 6
- Atypical pneumonia may require 2-4 days for fever resolution 6
Signs of Treatment Failure or Complications
Reassess and escalate care if:
- Persistent or worsening fever after 48-72 hours 1
- Development of hypothermia (may indicate sepsis or shock) 6
- Worsening respiratory status 1
- New oxygen requirement or increasing oxygen needs 1
- Poor feeding or signs of dehydration 6
Management of non-responders includes:
- Clinical and laboratory assessment to determine need for higher level of care 1
- Imaging evaluation (chest X-ray or ultrasound) to assess for complications like parapneumonic effusion, abscess, or necrotizing pneumonia 1
- Consider changing antibiotics: if started on amoxicillin alone, add macrolide for atypical coverage 6
- Investigate for resistant organisms or secondary infection 1
Management of Complications
Parapneumonic Effusion
If effusion develops:
- Small effusion (<10mm): Continue antibiotics alone, no drainage needed 1
- Moderate effusion: Obtain pleural fluid for culture via thoracentesis or chest tube 1
- Large effusion (>50% hemithorax): Chest tube with or without fibrinolytics, or VATS if not responding 1
- Antibiotic duration for complicated effusions: 2-4 weeks 1
Pulmonary Abscess or Necrotizing Pneumonia
- Initially treat with IV antibiotics 1
- Most will drain through bronchial tree without surgical intervention 1
- Consider image-guided drainage only for well-defined peripheral abscesses 1
Discharge Criteria (If Hospitalized)
Patient is ready for discharge when ALL of the following are met:
- Clinical improvement with decreased fever for 12-24 hours 1
- Oxygen saturation >90% on room air for 12-24 hours 1
- Stable mental status 1
- No increased work of breathing, tachypnea, or tachycardia 1
- Able to tolerate oral antibiotics and maintain hydration 1
Common Pitfalls to Avoid
- Do not reflexively prescribe antibiotics for all pneumonia cases in younger children, as most are viral; however, at age 13, bacterial etiology is more common and antibiotics are typically indicated 2, 5
- Do not assume hypothermia means improvement—it may signal worsening sepsis or shock 6
- Do not delay re-evaluation at 48-72 hours if patient not improving 1, 6
- Do not forget to consider atypical pathogens in school-aged children, especially if gradual onset and prominent cough 5
