Differentiating Upper from Lower Airway Compromise in Neonates

Abstract

Technologic advancements and improvements in supportive care have resulted in increased survival of very low birth weight and premature infants. With salvage of these high risk newborns, many difficult management problems arise. Respiratory distress of the newborn is the most common airway problem that affects these patients and subglottic edema or stenosis may frequently complicate management of the airway. Decision-making in airway maintenance and respiratory care can be problematic due to multiple factors that must be considered. The otolaryngologist is often consulted when upper airway obstruction is suspected. Relevant respiratory physiology is reviewed in order to help direct therapeutic decision-making. Parameters of assessment are enumerated and methods for choosing among therapeutic alternatives are presented. A paradigm to aid in differential diagnosis is described.
