Pediatric Airway Risks: Inefficient Mechanics of Breathing

In many ways pediatric anatomy and physiology predisposes a child to respiratory distress and respiratory failure. Inefficient mechanics of breathing is one major risk factor for infants and young children. This article discusses the ways the anatomy of a child creates inefficient mechanics of breathing and predisposes to respiratory distress and failure. Read More …

ETCO2: Valuable Vital Sign To Assess Perfusion

We routinely use ETCO2 to provide information on ventilation. But ETCO2 can also provide valuable information on the adequacy of cardiac perfusion. It can be an essential tool in ensuring optimal, high quality chest compressions during cardiac resuscitation. Read More …

Conscious Sedation: Is Your Patient Breathing?

Conscious sedation can alter respiration, which can lead to the vicious cycle of hypoventilation, hypercarbia, and hypoxia. If you don’t recognize inadequate respiration —and treat it— the patient can suffer injury or die. This article discusses the continuum of sedation and its effect on consciousness and respiration. Read More …

The MAC Blade, The Vallecula, and the Hyoepiglottic Ligament

Intubation with the MAC blade requires precise placement of the tip of the blade in the vallecula in order to manipulate the hyoepiglottic ligament and lift the epiglottis. This discussion uses illustration, Xray, and video to demonstrate proper intubation technique. Read More …

Learning Intubation: Head Position Effects Laryngeal View

When first learning intubation,  a beginner often concentrates on memorizing the key laryngeal anatomy. This is important of course. If you can’t recognize the vocal cords, you will not be able to successfully intubate. However, even more important to learning intubation is understanding how the larynx relates to the other structures in the head and neck. In order to intubate you must manipulate those other structures to bring the larynx into view. This post uses lateral X-rays and CT scan images to help novice intubators master the anatomical relationships they must know to intubate. Read More …

Announcing My Latest Article Has Been Published: “10 Rules for Approaching Difficult Intubation”

I’m excited. My latest article, titled, “10 Rules for Approaching Difficult Intubation, Always Prepare for Failure” has just been released in the journal supplement Airway Management, published by Anesthesiology News. Managing the difficult airway is one of the most challenging, risk ridden, and downright scary clinical problems in anesthesia. The article makes the Read More …

Bilateral Tension Pneumothorax: Harder To Diagnose

Tension pneumothorax is a life-threatening emergency. This article discusses several iatrogenic bilateral tension pneumothoraces occurring during intubation and emergency airway management. Read More …

PostObstructive Pulmonary Edema

Patients with postobstructive pulmonary edema (or P.O.P.E.) develop sudden, unexpected and potentially life-threatening pulmonary edema after relief of airway obstruction.  It can be mild or severe. My first experience with it was in 1983. The Case In 1983, we didn’t have pulse oximetry, end-tidal carbon dioxide monitoring or even automated Read More …

Anatomic Dead Space Affects Hypoventilation

Having a tidal volume close to, or smaller than the patient’s dead space can lead to significant hypercarbia, hypoxia, and respiratory failure. This article discusses the concept of dead space and it’s clinical use in recognizing hypoventilation and preventing hypoxia and hypercarbia. Read More …

GlideScope Technique For Intubation In Small Mouths

The GlideScope can be difficult to use in a patient with a small, narrow mouth. This article discusses a technique for improving successful intubation in that type of patient. Read More …

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. 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. My sincere wish is that this new book helps in the care of our littlest patients, no matter where they are. Read More …

NITROUS OXIDE: SHOULD WE USE IT?

When I was training, we used nitrous oxide on just about every anesthetic. It was easy to use. It was inexpensive. It didn’t tend to effect hemodynamics so it was useful in less stable patients when combined with an opioid. It helped speed induction through the second gas effect. It was not metabolized so renal and liver insufficiency were of less concern.

However, a lot more is now known about the pharmacologic disadvantages, and potential harm, of nitrous oxide in certain patients. N2O interferes with the B12/folate pathway and methylates DNA. This discussion reviews some of those patients at risk of harm from nitrous oxide exposure during anesthesia. Read More …

Intubation During Cardiac Resuscitation

Intubating patients during cardiac resuscitation is often challenging because of the circumstances surrounding the intubation. Excitement and apprehension accompany this life saving effort. In addition, The patient is often in a less than optimal position while chest compressions are in progress. You usually find the patient in one of two awkward positions: on the ground or in a bed. This article discusses techniques to better manage intubation during cardiac resuscitation, especially with the patient in an awkward position. Read More …

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 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. This article discusses 4 chief technical barrier to learning to intubate. Read More …

Not All Airway Emergencies Need Intubation

An emergency department physician I met the other day shared with me an experience from her hospital  that offers a good example of the fact that there are many different ways of managing an airway emergency in a child that don’t involve intubation. Medical management can sometimes avoid some of the risks of losing the airway that intubation might impose. Read More …

Remember That Respiratory Failure Is Not Always Due to Lung Failure

While assisting ventilation and protecting the airway are first priorities to stabilize a patient, treating the cause of the respiratory failure may require more than just ventilation and/or intubation. In fact, treating the cause can sometimes help you avoid the progression of respiratory distress to respiratory failure. If you don’t consider a potential problem or cause, you’re not going to be able to diagnosis it. This is a case of respiratory failure caused by hypovolemic shock and hypoglycemia in a child. Read More …

Exhaling During Manual Ventilation Is As Important As Inhaling

One of my readers recently asked a very important question about ventilating a patient with a bag-valve-mask device: “Is there an outlet for the expired air of the patient?” The answer is yes. When ventilating a patient we are concentrating, and rightfully so, on watching the lungs expand and verifying that we hear breath sounds. It is just as important to verify that your patient can exhale. All ventilation devices have a built in pressure relief valve, also called a pop-off valve, which allows you to balance the force needed to expand the lungs with the ability to the patient to passively exhale. Failure to allow exhalation can lead to patient injury from barotrauma. Read More …

Communication In A Crisis: A Case of Respiratory Depression In A Child:

When I’m teaching airway management to my Perioperative/OR nurses, I often recount the story of management of a young child’s postoperative respiratory depression. In addition to illustrating the importance of evaluating ventilation in addition to oxygenation, this case shows how good communication makes management of a critical event more effective. Read More …
