Learning to intubate is easier for some people than for others. Sometimes, no matter how knowledgeable you are about the theory of the technique, the novice can still struggle to bring it all together to pass the endotracheal tube. The anatomy can be confusing. Understanding how to place the laryngoscope blade and manipulate that anatomy can be challenging. And all the while you must be ever vigilant to protect those precious front teeth, avoid hypertension and tachycardia, and breathe for the patient at regular intervals.
I believe there are 4 chief barriers that inhibit learning how to intubate:
Failure to visualize how the outside anatomy links with the inside anatomy makes it hard to predict how deeply to insert the blade.
A mistaken belief that placing the laryngoscope blade itself is all that is needed to align the axes of the airway and reveal the larynx.
Failure to grasp the dynamic nature of the larynx, and the need to actively manipulate it during intubation.
A lack of understanding that intubation is not a sequence of isolated steps, but is instead a complex dance of interacting steps, each setting the stage for the next.
This discussion is going to assume some knowledge of the basic technique of intubation. If you’d like to review those basics you can find links for multiple prior in depth discussions at the end of this article.

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: the dreaded “can’t intubate-can’t ventilate” 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.

Our Healing Little HeroesFoundation founder dressed as Darth Vader at Ronald McDonald House, San Diego
Last weekend I spent time with the charity group Healing Little Heroes at the San Diego Rady’s Children’s Hospital, and Ronald McDonald House. The mission of Healing Little Heroes Foundation is to help pediatric patients in hospitals and outpatient settings to heal emotionally and mentally by appearing as Superheroes. My good friend, and general surgeon, Justin Wu, dressed below as Darth Vader, set up the Foundation.
On this day we arrived in full Star Wars costumes to entertain the kids and their families. I’m dressed as Queen Amidala. Which brings me to the topic of today’s conversation. Can hairstyle impact your intubation or even your anesthetic management? The answer is yes. There is no question that if Queen Amidala needed emergency intubation, that her hairstyle would get in the way. Continue reading →
During intubation, any liquid in the mouth that obscures the view of larynx not only hinders visualization, it risks aspiration. We’re used to being able to rapidly suction the mouth clear or secretions, blood, or vomit and then have a clear view of the larynx. But sometimes, either because of continued profuse bleeding or massive emesis, fluid continues to accumulate while we’re watching. How can you manage this situation and successfully intubate? Here I describe two cases, one involving blood and the other massive emesis, that required intubation through a large puddle of fluid. I offer tips and tricks to assist you in your future emergency management. Continue reading →
Direct laryngoscopy depends on being able to bring the 3 axes of the airway into alignment to see the larynx. Curved blades are commonly used, especially by beginners because they are more forgiving of less than optimal placement and provide more room to pass the tube. However, it’s important to use them correctly. This article will discuss intubation technique using a curved blade. Straight and curved blades use different techniques for bringing the larynx into view. For a discussion of how to use a straight blade click here.Continue reading →
Fall is the time of year when new students commonly begin to learn how to intubate. My first intubation was one of the first times I literally held someone’s life in my hands. I was nervous. The anesthesiologist teaching me tried to not look too anxious as I awkwardly grabbed my laryngoscope blade, fumbled while opening the patient’s mouth, and cautiously maneuvered the endotracheal tube into the trachea. It felt like time stopped until the tube was in place, after which the three of us (me, my teacher and my patient) all took a deep breath. Since then, over the last almost 37 years, I’ve intubated thousands of people in the U.S. and, as an international volunteer, eight countries.
So I thought it would be helpful at this time of year to discuss a step-by-step approach to intubation with the commonly used curved blade. Intubation, like a dance, is composed of steps that flow naturally from one to the next. The trick to a smooth intubation is to allow each step to blend seamlessly into the next. The text and illustrations below are excerpted from my book Anyone Can Intubate, as well as from my upcoming book on pediatric intubation, which I’m busy writing. Continue reading →
With fall comes the new crop of trainees eager to learn how to intubate. There will also be a new group of instructors teaching their first students to intubate. Teaching intubation skills on living patients, even those that have practiced on a manikin, can be challenging. It’s important to anticipate the common errors so we can safeguard our patients. Here I describe the all of the barriers, physical as well as psychological, that interfere with your student’s learning of the intubation technique. I offer tips on how to help your student conquer those barriers, while keeping your patient safe. Continue reading →
