Summary

Bronchoscopy is now widely used for the diagnosis and treatment of various respiratory diseases. However, the procedure is highly stimulating and provokes a strong stress response; because the airway is shared, patients are prone to hypoxia. With the growing emphasis on comfortable care, demand for anesthesia during bronchoscopy has increased. Deep sedation is the most common approach, but when administered in the supine position it often causes the tongue base to fall back. Both nasopharyngeal and oropharyngeal airways can relieve this obstruction, yet neither connects seamlessly to an oxygen supply line, resulting in insufficient oxygen delivery.We therefore replaced the nasopharyngeal airway with a wired endotracheal tube (size 4.0 or 4.5) inserted via the nose. This thinner tube couples easily to an oxygen line or ventilator circuit, partially relieves airway obstruction, and allows ample supraglottic oxygenation. The present study was designed to evaluate the feasibility and safety of this modified oxygen-delivery method in patients undergoing deep sedation for bronchoscopy.
