side by side comparison

Croup vs Epiglottitis: Barky Cough vs No Cough — Age, Onset, Airway Emergency Decision

Both present with stridor in a young child, but one responds to cool mist at home while the other kills by complete airway obstruction if you so much as look at the throat. Picking the wrong action — examining the oropharynx in epiglottitis — can be the lethal mistake on the NCLEX and at the bedside.

Comparison

Side-by-side2 compared
Dimension
Croup
Epiglottitis
Pathophysiology & risk
  • Viral (parainfluenza)
  • subglottic swelling
  • Age 6 mo–3 yr
  • gradual over 1–2 days
  • Bacterial (H. influenzae B)
  • supraglottic
  • Age 2–6 yr
  • sudden over hours
Signs & symptoms
  • ★Barky, "seal-like" cough
  • Inspiratory stridor
  • hoarse cry
  • Low-grade fever
  • no drooling
  • ★4 D's: drooling, dysphagia, dysphonia, distress
  • Tripod position
  • NO cough
  • High fever
  • toxic-appearing
Diagnostics & labs
  • Steeple sign (subglottic narrowing) on AP
  • ★Thumb sign (swollen epiglottis), lateral film
Nursing priorities
  • Oral dexamethasone
  • cool mist
  • Racemic epi for moderate–severe stridor
  • ★Do NOT examine throat / no tongue blade
  • Keep calm with parent
  • prep emergent intubation
Treatment & meds
  • Dexamethasone
  • nebulized racemic epinephrine
  • IV antibiotics (ceftriaxone) after airway secured
Patient teaching
  • Cool mist/humidified air
  • hydrate
  • Return if stridor at rest or retractions
  • Hib vaccine prevents it
  • Complete full antibiotic course
Red flags — escalate
  • Stridor at rest, retractions, cyanosis
  • Complete airway obstruction in minutes
Complications
  • Usually self-limiting
  • rarely intubation
  • Airway obstruction
  • sepsis
  • death

★ marks the fact that sets a column apart.

Clinical Pearl

Barky cough = croup, cool mist. Drooling, no cough, tripod = epiglottitis — hands off the throat.
