Epiglottitis: The 'Don't Agitate' Rule

If you're like me, epiglottitis is the case where every instinct you have about pediatric airway management needs to be suppressed — no IV first, no lying the child down, no tongue blade, no peeking. The rules are completely different from your standard pediatric induction. On the anesthesiology oral boards, epiglottitis tests whether you understand why the "don't agitate" doctrine exists and whether you have the clinical presence to enforce it when everyone around you wants to do something.

The classic presentation: a 3-5 year old with sudden high fever, drooling, dysphagia, and the classic "tripod" position — sitting upright, leaning forward, neck extended. The "cherry red epiglottis" is the textbook description. The key danger: the edematous epiglottis is obstructing a significant portion of the glottis already. Any agitation — pain from an IV, a crying response to being separated from parents, a tongue blade exam — can tip the child into complete obstruction.

The Core Logic

Epiglottitis is typically caused by Haemophilus influenzae type b (Hib), though the incidence has dropped dramatically with widespread vaccination. In unvaccinated or immunocompromised children, it still occurs. Adults can also get epiglottitis — the clinical picture is the same but typically more subacute.

The airway physics: the child is maintaining their airway by positioning. Supraglottic edema means the only patent airway is the narrow residual glottic opening they've found by sitting upright with neck extended. Change the position, agitate them to crying, or reduce their respiratory drive — and that residual opening closes. This is the precipitating event for complete obstruction and death.

The management strategy follows directly: preserve their positioning, minimize stimulation, bring them to the OR awake with parent present, and perform a controlled inhalation induction in the sitting or semi-recumbent position before transitioning to supine only once the airway is secured.

How the Examiner Tests This

Classic scenario: a 4-year-old is brought to the ER with drooling, high fever, and sitting in the tripod position. The ER nurse asks if she should put an IV in. "What do you say?" No. No painful procedures until the airway is secured. You do not establish IV access, you do not look in the mouth, you do not take a lateral neck X-ray that requires positioning — you take the child to the OR.

Follow-up probe: "The child is in the OR. How do you induce?" Inhalation induction with sevoflurane in 100% O2, child in a semi-upright position, parent in the room if possible. Spontaneous ventilation maintained throughout. You do not give a paralytic until you have confirmed the ability to ventilate. Once the child is adequately anesthetized, direct laryngoscopy — expect a swollen, cherry-red epiglottis making visualization difficult. Have ETTs 1-2 sizes smaller than predicted ready. ENT and surgical airway backup must be present.

The Board Trap

The IV-first trap: placing an IV before induction. This seems reasonable — you want access before induction. But the stick causes pain and crying, agitation spikes, and complete obstruction. IV access comes after inhalation induction, not before. The examiner will probe this specifically.

The "take a lateral neck X-ray" trap: lateral neck films are appropriate in stable, mild cases (where you suspect croup vs. epiglottitis) but are absolutely not appropriate in a child in the tripod position with respiratory distress. Moving a critically obstructed child to radiology, lying them supine, and asking them to hold still for a film is a way to cause a cardiac arrest in the X-ray suite. The diagnosis is clinical. Airway management takes priority.

Lead-In Phrases

• "My plan is to disturb this child as little as possible — no painful IV, no examination of the oropharynx, no positional change — until we are in the operating room with an ENT surgeon present and ready for a surgical airway."
• "I will perform an inhalation induction with sevoflurane in 100% oxygen, keeping the child semi-upright, maintaining spontaneous ventilation throughout. I will not administer a neuromuscular blocker until I have confirmed I can ventilate."
• "I will have ETTs 1-2 sizes smaller than age-predicted prepared — the epiglottic edema significantly reduces the effective glottic diameter."
• "ENT must be present in the room before I begin induction — this is a potential surgical airway case, not a standard pediatric intubation."
• "After the airway is secured, I will establish IV access and begin antibiotics — ceftriaxone is the standard first-line coverage for Hib epiglottitis."

FAQs

How long do these children stay intubated?

Typically 24-48 hours. Epiglottic edema responds rapidly to antibiotics, and most children can be extubated in the ICU within 1-2 days. Before extubation, direct laryngoscopy or a leak test can confirm edema has resolved. Extubation should be done in a controlled setting with surgical airway backup available.

What if the child loses the airway during inhalation induction?

This is the nightmare scenario. If complete obstruction occurs before intubation: attempt bag-mask ventilation, call ENT immediately for surgical airway, attempt rigid bronchoscopy (ENT can often pass a bronchoscope through even a severely swollen glottis), and prepare for needle or surgical cricothyrotomy. This is why ENT must be in the room before you start.

Does this apply to adult epiglottitis?

The same principles apply — don't agitate, prioritize airway, have surgical backup. Adults typically have a more insidious course that allows time for awake fiberoptic intubation, which is often preferable to inhalation induction in adults who can cooperate. The key difference: adults can usually be topicalized and scoped while sitting up, which gives you more control than an inhalation induction.

Epiglottitis is a case where doing less is doing more. The examiner is watching whether you'll hold the line against unnecessary interventions when everyone else in the room is anxious to "do something." Practice the structured "no-agitation" protocol in Boards Bot until your first instinct is restraint.
