Insights
Subglottic stenosis in infants, a complication of endotracheal intubation, can cause difficult airways. A rigid stylet aided intubation in a case of severe stenosis, offering an alternative approach.
Area of Science:
- Pediatric Critical Care
- Emergency Medicine
- Anesthesiology
Background:
- Subglottic stenosis is a common complication following endotracheal intubation in pediatric patients.
- This condition can lead to significant airway difficulties during subsequent respiratory events.
- Existing difficult airway algorithms guide management of respiratory failure, emphasizing invasive access as a last resort.
Observation:
- A 4-month-old infant presented with stridor and respiratory failure secondary to croup.
- The infant had a history of prior endotracheal intubation, which had resulted in severe subglottic stenosis.
- Tracheal intubation was challenging due to the narrowed subglottic segment.
Findings:
- Successful endotracheal intubation was achieved using a rigid endotracheal tube stylet.
- The stylet facilitated the passage of the endotracheal tube through the stenotic portion of the airway.
- This case highlights a potential alternative method for managing difficult airways caused by subglottic stenosis.
Implications:
- Emergency physicians should be aware of non-standard techniques for managing difficult airways.
- A rigid stylet can be a valuable tool for tracheal intubation in cases of severe subglottic stenosis.
- Consideration of this technique should follow evaluation of conventional methods and potential complications.
Background:
Subglottic stenosis is a frequent complication of endotracheal intubation in children and can create a difficult airway situation for subsequent respiratory illnesses. Difficult airway algorithms are an essential aid when dealing with respiratory failure in clinical situations where ventilation or intubation is unsuccessful.
Case Report:
A 4-month-old infant with a history of previous endotracheal intubation required endotracheal intubation for stridor and respiratory failure due to croup. There was difficulty intubating the trachea due to severe subglottic stenosis that developed following the previous episode of endotracheal intubation. Successful intubation was facilitated by the use of a rigid endotracheal tube stylet to facilitate passage of an endotracheal tube through the stenotic segment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Difficult airway algorithms recommend the use of invasive airway access only as a last resort and noninvasive airway access should be explored prior to their use. The use of a readily available rigid stylet as an alternative method for tracheal intubation should be considered only after more conventional techniques and potential complications have been considered.
