Management of Pediatric Complicated Pneumonia

Initial Assessment and Hospitalization

The American Academy of Pediatrics and the Infectious Diseases Society of America recommend that children with complicated pneumonia should be hospitalized for management, as defined by the presence of pleural effusion, empyema, necrotizing pneumonia, or lung abscess 1, 2
Admission to ICU is indicated for children with need for invasive mechanical ventilation, non-invasive positive pressure ventilation, impending respiratory failure, sustained tachycardia, inadequate blood pressure, or need for pharmacologic support, as well as those with pulse oximetry <92% on inspired oxygen of ≥0.50 or altered mental status due to hypercarbia or hypoxemia 2, 3

The Infectious Diseases Society of America recommends obtaining chest radiographs in all hospitalized patients to document infiltrates and identify complications, and blood cultures should be obtained in children with complicated pneumonia 1, 2, 4
Consider ultrasound to assess for pleural fluid and guide management decisions, and for non-responding patients, consider additional diagnostic procedures such as bronchoalveolar lavage (BAL) for mechanically ventilated children or percutaneous lung aspirate in persistently ill children without microbiologic diagnosis 4, 5

The Infectious Diseases Society of America recommends that initial empiric antibiotic therapy should target the most likely pathogens, particularly Streptococcus pneumoniae and Staphylococcus aureus, and for hospitalized children with complicated pneumonia, intravenous antibiotics are recommended 2, 4, 6
When blood or pleural fluid cultures identify a pathogen, antibiotic therapy should be adjusted based on susceptibility results, and for culture-negative complicated pneumonia, antibiotic selection should follow recommendations for hospitalized CAP patients 6

Small effusions (<10mm rim) can be managed with antibiotics alone without drainage, but for moderate to large effusions, management options include chest tube placement alone, chest tube with fibrinolytic therapy, or video-assisted thoracoscopic surgery (VATS) 4, 6
VATS should be performed when there is persistence of moderate-large effusions and ongoing respiratory compromise despite 2-3 days of chest tube management with fibrinolytic therapy, and chest tube can be removed when pleural fluid drainage is <1 mL/kg/24h and there is no intrathoracic air leak 6

Children who are not responding to initial therapy after 48-72 hours should be managed by clinical and laboratory assessment of current severity, imaging evaluation to assess progression of pneumonia or parapneumonic process, and further investigation for persistent pathogens, development of resistance, or secondary infection 4
Follow-up chest radiographs are not routinely required in children who recover uneventfully, but should be obtained in children who fail to demonstrate clinical improvement, have progressive symptoms or clinical deterioration within 48-72 hours of antibiotic therapy, or have complicated pneumonia with worsening respiratory distress or persistent fever not responding to therapy 5

Patients are eligible for discharge when they have documented overall clinical improvement, including level of activity, appetite, and decreased fever for at least 12-24 hours, consistent pulse oximetry measurements >90% in room air for at least 12-24 hours, and ability to tolerate oral antibiotics if transitioning to outpatient therapy 4, 7
