A 5-year-old boy is brought to the emergency department by his parents due to a sudden onset of high fever and severe difficulty swallowing. The parents report he has been drooling excessively and has refused to eat or drink for the past 6 hours. He has not had a barking cough. Past medical history is negative. He is febrile at 39.8 C, tachycardic at 150/min, and tachypneic at 30/min. His oxygen saturation is 94% on room air. On physical examination, he appears anxious and is sitting in a forward-leaning, tripod position. His voice sounds muffled. He is drooling saliva and appears toxic.
Which of the following is the most appropriate next step in the management of this patient?
The correct answer is:
A) Direct visualization of the airway in the operating room
This patient is presenting with the classic clinical signs of acute epiglottitis, a life-threatening medical emergency. The classic presentation involves the four Ds: drooling, dysphagia, dysphonia, and distress. Patients often adopt the tripod position to maximize airway patency. The absence of a barking cough helps distinguish this from croup. Because the epiglottis can swell rapidly and cause complete airway obstruction, the most important management priority is to secure a definitive airway in a controlled environment. Direct visualization and endotracheal intubation should be performed by experienced personnel, such as an anesthesiologist or otolaryngologist, in the operating room where emergency surgical airway equipment is immediately available. Manipulation of the airway in the emergency department, such as using a tongue depressor to inspect the pharynx, is strictly contraindicated as it may provoke sudden, complete airway obstruction.
Answer choice B: Lateral neck radiograph, is incorrect. While a lateral neck film may show the classic thumbprint sign representing an edematous epiglottis, it is not the next step in an unstable or toxic-appearing patient. Transporting a child with potential airway compromise to the radiology suite puts the patient at risk of sudden airway collapse in an environment without immediate surgical airway capabilities.
Answer choice C: Nebulized racemic epinephrine, is incorrect. This is the treatment of choice for croup (laryngotracheobronchitis), which involves subglottic edema. Dexamethasone is also administered. Croup presents with a barking cough and is typically a less toxic-appearing condition. Nebulized epinephrine does not address the supraglottic obstruction caused by epiglottitis and will delay definitive airway management.
Answer choice D: Observation in the emergency department, is incorrect. Epiglottitis is a progressive, potentially fatal condition. Simply observing the child is dangerous because the clinical status can deteriorate rapidly. The airway must be secured proactively.
Answer choice E: Oral antibiotics, is incorrect. While this patient will eventually require intravenous antibiotics, typically a third-generation cephalosporin like ceftriaxone, to treat the underlying infection, commonly Haemophilus influenzae type b. However, medication administration is secondary to airway stabilization.
Key Learning Point
Acute epiglottitis is a pediatric emergency characterized by the sudden onset of fever, drooling, dysphagia, and a muffled voice. The definitive management is securing the airway in a controlled setting (operating room) by experienced personnel. Diagnostic maneuvers that agitate the child or involve airway manipulation (including tongue depressors or radiology transport) should be avoided in unstable patients.
