A 4-year-old girl is brought to the emergency department by her parents because of the sudden onset of high fever, severe sore throat, and difficulty breathing. Past medical history is negative. Her immunization history is incomplete. On physical examination, she is sitting on the edge of the examination table, leaning forward with her chin thrust out and her mouth open, and is drooling. She appears anxious and is using accessory muscles to breathe. Her voice is muffled, and she has a soft inspiratory stridor.
Which of the following is the most appropriate next step in the management of this patient?
The correct answer is:
C) Perform immediate endotracheal intubation in the operating room
The patient is presenting with the classic clinical features of acute epiglottitis, a life-threatening inflammatory condition of the supraglottic structures. While the incidence has decreased significantly due to the Haemophilus influenzae type b (Hib) vaccine, it remains a critical diagnosis in under-immunized children. The hallmark presentation is the 4 Ds: Drooling, Dysphagia, Dysphonia (muffled voice), and Distress (inspiratory stridor and tripod positioning). In cases of suspected epiglottitis, the most appropriate next step is airway stabilization in a controlled environment. Any attempt to visualize the throat in a distressed child can trigger laryngospasm and complete airway obstruction. Management should occur in the operating room with an anesthesiologist and otolaryngologist present to perform immediate endotracheal intubation or, if necessary, an emergency tracheostomy.
Answer choice A: Examine the posterior oropharynx with a tongue depressor, is incorrect. This is strictly contraindicated in the emergency department for patients with suspected epiglottitis. The stimulation of the gag reflex can cause immediate, total airway occlusion.
Answer choice B: Obtain a lateral neck radiograph, is incorrect. While a lateral neck X-ray can show the classic thumbprint sign due to a swollen, enlarged epiglottis, imaging should never delay airway protection in a patient showing signs of respiratory distress such as stridor, tripod positioning, and drooling. Radiographs are reserved for stable patients where the diagnosis is uncertain.
Answer choice D: Start intravenous dexamethasone and nebulized epinephrine, is incorrect. This is the standard treatment for croup (laryngotracheobronchitis). Croup typically presents with a barky cough and a slower onset. Epiglottitis is a bacterial cellulitis that does not respond to these measures and requires definitive airway management and IV antibiotics.
Answer choice E: Transport the patient to the radiology suite for a neck CT, is incorrect. Transporting an unstable patient with potential airway obstruction to a remote imaging suite like CT is dangerous. Diagnostic imaging should only be performed if the patient is stabilized and the diagnosis remains in question.
Key Learning Point
Epiglottitis is a pediatric emergency characterized by the tripod position, drooling, and stridor. The priority is maintaining a calm environment and moving the patient to the operating room for controlled intubation. Diagnostic findings include the thumbprint sign on lateral X-ray and a cherry-red epiglottis on direct laryngoscopy.
