Background

  • Most common site of infection in neonates

Bugs by Age Group

Clinical Features

Fever and tachypnea are sensitive but not specific

  • Fever
  • Cough
    • Productive cough is rarely seen before late childhood

Differential Diagnosis

Pediatric fever

Evaluation

  • Absence of tachypnea, respiratory distress, and rales/decreased breath sounds rules-out with 100% sensitivity
  • Imaging
    • CXR is not the gold standard!
    • Cannot differentiate between viral and bacterial (but lobar infiltrate more often bacterial)
    • Consider for:
      • Age 0-3mo (as part of sepsis workup)
      • <5yr with temperature >102.2, WBC >20K and no clear source of infection
      • Ambiguous clinical findings
      • Pneumonia that is prolonged or not responsive to antibiotics
  • Consider rapid assays for RSV, influenza
  • Blood/nasal culture are low yield
    • in prospective study, 91 blood cultures needed for one positive result for CAP; but in ICU one child had bacteremia for every 24 cultures obtained, one for every 12 with parapneumonic effusion [1]
    • consider for sicker ones, those with effusions

Treatment[2]

Newborn

1-3 Month

>3mo - 18 years

Disposition
