Stridor in Newborns: Evaluation & Management

First, Briac and Gopi discuss how a newborn with stridor can present. Though stridor does occur among NICU babies, most of Briac’s patients are referred by outpatient pediatricians. They discuss a list of questions to ask while taking a history and emphasize the importance of assessing growth trends. In the absence of other medical problems, declining weight can suggest severe aerodigestive tract abnormality. Any pathology that narrows the airway can cause stridor: in infants, these include laryngomalacia, vallecular cysts, subglottic cysts, tracheal rings, and bilateral vocal fold immobility.

Then, Briac talks listeners through his physical exam, with special attention paid to flexible fiberoptic laryngoscopy. Briac shares his tips to maximize visualization and clinician ergonomics when scoping a small child. If bilateral vocal fold immobility is suspected, Briac recommends performing a longer fiberoptic exam so that the clinician can determine whether vocal fold immobility is present at rest or due to an uncomfortable child crying.

Next, Gopi and Briac differentiate between mild, moderate, and severe laryngomalacia and the indications for going to the operating room for an airway evaluation. As 20% of children with laryngomalacia have secondary airway lesions, a meticulous laryngoscopy/bronchoscopy is mandatory in these patients when a trip to the OR is required. Moving to the OR, Briac talks about his workflow when performing diagnostic bronchoscopy/laryngoscopy (DLB) to assess various causes of stridor. The episode concludes with Briac’s meditations on airway surgery as a team endeavor.
