    Long Range Optical Coherence Tomography of the Neonatal Upper Airway for Early Diagnosis of Intubation-related Subglottic Injury

    Subglottic edema and acquired subglottic stenosis are potentially airway -compromising sequelae in neonates following endotracheal intubation . At present, no imaging modality is capable of in vivo diagnosis of subepithelial airway wall pathology as signs of intubation - related injury . OBJECTIVES: To use Fourier domain long - range optical coherence tomography (LR-OCT) to acquire micrometer-resolution images of the airway wall of intubated neonates in a neonatal intensive care unit (NICU) setting and to analyze images for histopathology and airway wall thickness. METHODS: LR-OCT of the neonatal laryngotracheal airway was performed a total of 94 times on 72 subjects (age 1-175 days, total intubation ...
