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.
