Background

  • <2yr old (peak 2-6mo age)
  • Respiratory syncytial virus (RSV) causes ~70% of cases[1]
  • Preemies, neonates, congenital heart disease are at risk for serious disease
  • Peaks in winter
  • Duration = 7-14d (worst during days 3-5)
  • Inflammation, edema, and epithelial necrosis of bronchioles

Clinical Features

Differential Diagnosis

Pediatric Shortness of Breath

Pulmonary/airway

Cardiac

Other diseases with abnormal respiration

Evaluation

  • Consider rapid RSV testing
    • However, RSV is NOT linked apnea or acute severity (compared to other causes of bronchiolitis)[2][3]
    • You should NOT use RSV status to drive admission decisions and admission locations (eg, ward, step-down unit, ICU)[4]</ref>[5]
  • CXR
    • Not routinely necessary
      • May lead to unnecessary use of antibiotics (atelectasis mimics infiltrate)
    • Consider if
      • Diagnosis unclear
      • Critically ill

Concurrent infection risk

Infants <60 days with RSV bronchiolitis and fever

  • Low risk of bacteremia and meningitis in RSV+, still appreciable UTI risk
  • Recommended to still obtain UA in cases of bronchiolitis w/ fever. BCx and CSF not necessary if >28 days old

Management

  • Hydration for all infants

Oxygen

It is reasonable to not perform continuous oximetry on infants and children with bronchiolitis[6]

  • O2 (maintain SaO2 >90%)
    • oxygen saturation alone should not dictate admission[7]
  • High flow nasal cannula
    • multicenter randomized trial showed infants with bronchiolitis and hypoxemia required less escalation of therapy than standard oxygen [8]

Suctioning

There is insufficient data to make an evidence-based recommendation about suctioning.

  • Nasopharyngeal suctioning may temporarily relieve symptoms
  • The use of routine “deep” suctioning may lead to increased length of stay based on one small study [6]

Hypertonic saline

AAP recommends as a possible intervention, but 2014 SABRE trial found no change in discharge or adverse events with nebulised HS.[9]

  • No decrease in hospital admission using 3% HS in 2017 multi-center, RCT for moderate-severe bronchiolitis, with mild adverse events such as worsening of cough were significantly higher in the HS group[10]
  • Only consider administering to infants who require hospitalization[6] (Class B))
    • Suction nares / nasal saline drops

Not Indicated

Randomized controlled trials of bronchodilator or corticosteroid therapy have shown mixed results. Bronchodilators could aggravate the symptoms.[11][12][13]

Disposition

Consider Admission

  • Age <3months
  • Preterm (<34wks)
  • Underlying heart/lung disease
  • Initial SaO2 <90%
    • Sa02 alone should not be used as the only factor for admission[15]
  • Unable to tolerate PO
  • Tachypnea with accessory muscle use
