Retrograde Orotracheal Intubation with a Double-Lumen Tube

Abstract

Difficult airway management in thoracic surgeries is a peculiar subject due to the demands of monopulmonary ventilation with double-lumen tubes. Flexible bronchoscopy guidance is extremely important, but it is not always available. The objective of this report was to describe a case of retrograde selective orotracheal intubation in the absence of specific endoscopy equipment for the procedure. This is a patient with a history of retosigmoidectomy, admitted for a right thoracotomy for a lung lesion. Preoperative anesthetic evaluation did not reveal any clinical and physical exam particularities. After anesthetic induction and ventilation with face mask, two attempts of orotracheal intubation under direct laryngoscopy were ineffective due to difficult visualization of the vocal folds (Cormack-Lehane grade III). Due to the unavailability of specific material for selective endoscopic intubation it was decided to use the retrograde technique using the double-lumen tube. The patient was extubated in the operating room shortly after the end of the surgery without complications secondary to the alternative technique. Retrograde selective orotracheal intubation is a minimally invasive technique, low cost, safe, and extremely useful whenever flexible bronchoscopy is not available.
