Background

Croup = laryngotracheobronchitis
Affects 6 mo-3 yr (peak in 2nd year)
Fall & winter
Etiology
- Parainfluenza (50%), RSV, rhinovirus
  - Consider diphtheria if not immunized
Must rule-out foreign body

Diagnosis

1-2 day of URI followed by barking cough, stridor
Low-grade fever
NO drooling or dysphagia
Duration = 3-7d, most severe on days 3-4

Work-Up

Consider CXR if concerned about alternative dx
1. Steeple sign on AP (not Sp, not Sn)
Consider nasal washings for RSV, parainfluenza, influenza.

Treatment

Steroids
1. Give to all pts with croup
  1. Dexamethasone 0.15-0.6mg/kg PO/IM (max 10mg)
Epineprhine (nebulized)
1. Give for moderatate-severe cases
Do NOT give albuterol (may worsen edema (vasodilation))

Disposition

Consider discharge if:
1. 3hr since last epinephrine
2. Able to tolerate PO
3. Nontoxic apperance
