Retrograde Intubation Over a Flexible Fiber-Optic Bronchoscope

Abstract

Traditional retrograde intubation consists of tracheal intubation performed over a guide wire inserted into the trachea inferior to the vocal cords and then passed transorally or transnasally. This intubation technique is reserved for patients with a difficult airway when other methods such as blind nasal intubation or video laryngoscopy fail. A guide wire passed blindly in a retrograde fashion, however, is not without its own constraints. This case report presents the anesthetic management of a 23-year-old Duchenne muscular dystrophy patient with substantial scarring from a previous tracheostomy stoma and limited mouth opening. The patient underwent a retrograde fiber-optic transnasal intubation without the use of a guide wire for a tracheostomy revision procedure, followed by a second tracheostomy revision and retrograde fiber-optic transoral intubation 7.5 months later. This report demonstrates a novel technique for intubating patients with difficult airways. The use of a flexible fiber-optic bronchoscope for a retrograde intubation mitigates complications that can arise using traditional retrograde intubation over a guide wire and increases the likelihood of successful intubation.
