Announcing My New Book: Pediatric Airway Management: A Step-by-Step Guide

At long last, after two years of writing (and rewriting),  illustrating, and  filming  on-line videos, I’m excited to announce the publication of my new book Pediatric Airway Management: A Step-by-Step Guide, by Christine E. Whitten MD.

Anyone who rarely cares for children tends to be anxious when faced with a small child’s airway. This is true even if they are comfortable with adult airway management.

My goal for this book is to demystify basic pediatric airway management. I want to give you the skills you need to recognize when a child is in trouble and act quickly to safeguard that child, including helping them breathe if necessary. Continue reading

When Learning Intubation Is Hard

Learning to intubate is easier for some people than for others. Sometimes, no matter how knowledgeable you are about the theory of the intubation 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:

  1. Failure to visualize how the outside anatomy links with the inside anatomy makes it hard to predict how deeply to insert the blade.
  2. 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.
  3. Failure to grasp the dynamic nature of the larynx, and the need to actively manipulate it during intubation.
  4. 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 intubation technique. If you’d like to review those basics you can find links for multiple prior in depth discussions at the end of this article.

Intubation: Step By Step

Learning intubation technique can be challenging. 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

Tips To Teaching Intubation

To teach intubation skills on living patients, even those that have practiced on a manikin, can be challenging. 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. 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

Assisting Ventilation With Bag-Valve-Mask

As an anesthesiologist, I often run to emergencies where the patient is not breathing adequately and requires intubation. However, before any intubation, a patient in respiratory distress/failure needs ventilation. Providers who have passed ACLS are often able to ventilate an apneic patient well because they have practiced on the manikin. However, I often see that providers have more difficulty trying to assist ventilation of a patient who is still breathing spontaneously.

The typical inexperienced provider will try to provide large, slow breaths just as they were taught in ACLS. Unfortunately these breaths are often out of synch with the patient’s own breathing. Squeezing the bag while the patient is exhaling means that your inflation pressure must not only overcome the diaphragm, but also reverse the passive outflow of air, the elastic recoil of the lungs, and the rebound of the chest wall combined. The vocal cords may be closed. Ventilating out of synch with the patient won’t be as effective. The breath you deliver will take the path of least resistance to enter the stomach or escape from the mask. It often makes the patient cough.

Even worse,  providers will occasionally hesitate to try to assist a patient’s breathing while waiting for the intubation team because they feel they don’t know how. Delay in improving ventilation can place your patient at higher risk of complication. This is unfortunate because in many ways assisting ventilation is even easier than manually ventilating an apneic patient. Let’s see why. Continue reading
