Insights
Fiberoptic intubation can be challenging in infants with large epiglottises and supraglottic growths. Direct laryngoscopy and air bubbling can aid emergency physicians in securing the airway.
Area of Science:
- Pediatric Airway Management
- Emergency Medicine
Background:
- Fiberoptic bronchoscope-guided tracheal intubation is standard for supraglottic growths.
- Success depends on space between epiglottis and growth in infants.
Observation:
- Inability to pass fiberscope tip between epiglottis and supraglottic growth in an infant.
- Successful use of direct laryngoscopy to increase airway space.
Findings:
- Direct laryngoscopy facilitated passage of the fiberscope.
- "Bubbling of air" technique aided glottic opening identification.
Implications:
- Emergency physicians must be aware of alternative airway management techniques.
- These skills are crucial for life-saving interventions in challenging pediatric cases.
- Direct laryngoscopy can be a valuable adjunct when fiberoptic intubation is difficult.
Background:
Fiberoptic bronchoscope-guided tracheal intubation is the gold standard for managing patients with supraglottic growths. In infants with a large and overhanging epiglottis, the success of fiberoptic-guided intubation relies heavily on the available space between the inferior surface of the epiglottis and the posterior pharyngeal wall or, more specifically, the superior surface of the supraglottic growth.
Case Report:
We describe the inability to negotiate the tip of the fiberscope between the epiglottis and the supraglottic growth and the successful use of direct laryngoscopy to improve the available space along with the usefulness of "bubbling of air" to locate the glottic opening in an infant. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We emphasize the role of the emergency physician in managing such patients. Most of the time, the setting is not ideal in such emergency situations and the most qualified clinician to treat them is the emergency physician. The knowledge and skills of the emergency physician, along with awareness of the possible techniques for airway management, can be lifesaving.
