4 D's: Drooling, Dysphagia, Dysphonia, Distress
Tripod position, high fever

📚 Epiglottitis — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Epiglottitis is a rapidly progressing bacterial infection causing severe inflammation of the epiglottis that can completely obstruct the airway. It was classically caused by Haemophilus influenzae type B (Hib) and is now rarer due to the Hib vaccine. It is a true airway emergency presenting with the classic tripod position and the 4 D's: drooling, dysphagia, dysphonia, and distressed inspiratory effort.
🔑
Key points
Understand these first
Onset is abrupt with high fever, sore throat, and a toxic, ill appearance.
The child sits upright in a tripod position, leaning forward with chin out and tongue protruding to keep the airway open.
Drooling occurs because the child cannot swallow secretions due to painful dysphagia.
The voice is muffled or absent and there is no spontaneous cough (unlike croup).
Inspiratory stridor and severe respiratory distress develop quickly.
The epiglottis appears cherry-red and swollen.
✅
Nursing priorities
What to do, in order
Keep the child calm, upright, and with the parent; do not force them to lie down.
Do NOT inspect the throat or insert anything into the mouth, as this can trigger complete obstruction.
Prepare for emergency intubation or tracheostomy and keep airway equipment at the bedside.
Administer humidified oxygen, IV antibiotics, and corticosteroids as ordered once the airway is secured.
Notify the provider and stay with the child continuously; have the child accompanied to any imaging.
🚩
Red flags — report now
Escalate immediately
Never use a tongue depressor or throat swab or take an oral temperature; airway spasm and total obstruction can result.
Drooling, tripod positioning, muffled voice, and stridor together signal imminent airway loss.
Any sudden agitation, cyanosis, or decreasing responsiveness requires immediate airway intervention.
Do not leave the child alone or delay calling the rapid response or anesthesia team.

Labs & values
Numbers to know
Oxygen saturation: normal 95-100%
WBC: normal 5,000-10,000/mm3, often elevated with bacterial infection

Patient teaching
What patients must know
Ensure children complete the Hib vaccine series to prevent epiglottitis.
Seek emergency care immediately for sudden high fever with drooling, muffled voice, and difficulty breathing.
After recovery, complete the full course of prescribed antibiotics.
