🫁 Croup vs Epiglottitis

A barking cough or a drooling child sitting forward. One goes home; the other needs a surgeon and nothing in the mouth.

⚖️ Telling them apart

Two children side by side - one with croup, unwell but interactive, and one sitting bolt upright in the tripod position drooling - with the airway under each: narrowed below the cords in croup, a swollen epiglottis over the opening in epiglottitis.
One goes home and the other needs a surgeon, and the child in front of you tells you which. Nothing goes in the mouth of the second one. Swipe it sideways if it is cut off, or tap to open it full size.

Children have narrow airways, so a small amount of swelling causes a large obstruction. These two are the classic pair, and confusing them is dangerous.

⭐ The 4 Ds of epiglottitis

Drooling · Dysphagia · Dysphonia · Distress

A child who is drooling, sitting forward and will not talk is epiglottitis until proven otherwise.

🚨 The single most important rule

In suspected epiglottitis, put NOTHING in the child's mouth. No tongue depressor, no throat swab, no oral thermometer, no oral airway. Any of them can trigger complete airway obstruction.

Do not lie the child down either. Keep them upright, calm and with a parent.

1Do not examine the throat
2Keep upright with the parent; do not separate them
3Keep them calm — crying worsens obstruction
4Oxygen as tolerated; call for senior help
5Intubation in theater, then IV antibiotics

Why keeping them calm is a clinical intervention: crying and struggling increase airflow turbulence through an already swollen airway and can close it completely. Letting the parent hold the child is treatment, not kindness.

✅ Prevention

The Hib vaccine has made epiglottitis rare — given from 2 months. It is one of vaccination’s clearest success stories, and worth saying to hesitant parents.

🩺 Croup care

  • Cool mist or cool night air — many children improve on the drive to hospital
  • Corticosteroids (dexamethasone) reduce airway edema
  • Nebulized epinephrine for moderate to severe stridor; observe afterwards for rebound
  • Fluids; keep the child calm — same principle as above
  • Most are managed at home

No sedatives - they mask the signs of worsening respiratory distress.

🚨 When croup needs hospital

  • Stridor at rest, not just when upset
  • Retractions that are worsening
  • Restlessness or drowsiness — hypoxia
  • Cyanosis; rising respiratory rate then a falling one as they tire

A quiet, floppy child is more worrying than a screaming one. Silence in respiratory distress means exhaustion.

🎯 NCLEX traps

  • Barking cough = croup. Drooling + tripod + no cough = epiglottitis
  • Nothing in the mouth with epiglottitis
  • Keep the child upright and calm with the parent
  • Croup gets cool mist and steroids; epiglottitis gets theater and antibiotics
  • No sedatives in either
  • Hib vaccine prevents epiglottitis
