Here’s a great example of using a dual endoscopy technique not only to manage a potentially difficult airway, but also to give more insight into the pathology itself. This short video shows the intubation of a patient who presented for thyroid surgery with a large mass compressing the trachea, as well as some other predictors of difficult intubation: slightly limited mouth opening, a short neck, and potentially challenging dentition. We wanted to see the position and degree of tracheal compression present before advancing the tracheal tube, but also to place the modified tube with nerve monitoring sensor precisely at the right depth.
Video laryngoscopy with a Mackintosh-style blade provided good access to the airway, and allowed us to spray the vocal cords and trachea with local anaesthetic, avoiding neuromuscular blockers. We could then place the tip of the tube through the vocal cords and observe the trachea and subglottic space using the Bonfils optical stylet. Both images are displayed side-by-side to coordinate view. It’s a good tip to put the device in your left hand on the left side of the screen (and corresponding right-handed device on the right) to promote good orientation.
If you’ve tired dual endoscopy for a clinical case, pop a description or brief story in the comments!
