The GlideScope Video Laryngoscope (GVL) is an extremely useful tool for managing challenging intubations, but it can be more difficult to use if your patient has a small mouth and a high arched, narrow palate. The problem: once the GlideScope is in place in a small mouth, maneuvering the endotracheal tube around it and into the posterior pharynx can be challenging. If you can pass the endotracheal tube (ETT) at all, the cuff tends to scrape against the teeth, risking rupture. However, there is a modified GlideScope technique you can use in those situations.

We have just finished another round of Critical Event Training for my hospital’s Anesthesia and OR staff. One of the scenarios we ran was how to manage a failed airway emergency: the dreaded “can’t intubate-can’t ventilate” airway emergency scenario.
As an instructor, it’s important for me to set the stage realistically. The more real the scenario, the more the providers will learn and be able to apply the information should they ever find themselves in a comparable situation. I must observe as the trainees respond to the emergency, and then help the trainees self-analyze what went well — or not so well — during the scenario. Of course, discussion of how things went during a training scenario always leads to sharing of examples from past real life scenarios. And after 37 years of practice I’ve had a lot of sharable experiences.
One past case we discussed is particularly appropriate for those students around the country who are just beginning to learn airway management because the solution rested in basic airway management techniques. This case, involving an intubation in an ICU patient that turned into a “can’t intubate/can’t ventilate” emergency demonstrates how returning to the basics of airway management can sometimes be the way to save your patient from harm.

Awake intubation with the GlideScope can be an especially helpful technique when intubation of a difficult airway under direct vision is optimal. One of the most challenging scenarios to face is a tumor in the airway. Working closely with your surgeon is important. In this particular case, we actually had a video available of what this 8 mm airway polyp looked like popping in and out of a laryngeal opening of about the same size with each breath like a potential cork. According to the surgeon our patient had come to the clinic because she had been experiencing some increased shortness of breath. Having the video was a rare advantage.

Glidescopes, one of the several videolaryngoscopes in use, are very easy to use. However, intubation with the Glidescope is very different than direct laryngoscopy. I have seen many novice Glidescope users struggle to intubate, despite having great views of the larynx. Failure to recognize the differences of using the Glidescope can make intubation not only frustrating but also hazardous to your patient. Beginners almost always make the same few easy to correct mistakes. Let’s explore those mistakes and discuss how to correct them. Continue reading
