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.
The child was an 18 month old girl whose older brother had been playing with laundry detergent pods. He had offered a pod to his little sister, who promptly put it in her mouth and chewed it, releasing the liquid. Her mother had brought her to the emergency room with respiratory distress. The child had severe stridor and was breathing at 40 times a minute. Oxygen saturation was 92%. She was awake and alert but anxious.
The ED doctor recognized significant airway obstruction and was concerned that the obstruction could worsen if the edema got worse. She immediately called for an anesthesiologist and a Head and Neck surgeon to come to the Emergency Department to evaluate the child. While waiting, she gave 10 mg of IM decadron and treated the child with nebulized racemic epinephrine. She attached a pulse oximeter and left the child sitting on her mother’s lap and otherwise did not disturb the child, trying to avoid making her cry. By the time the anesthesiologist and surgeon arrived the stridor, although still present, sounded better.
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.

Needle cricothyrotomy or percutaneous jet ventilation (PCJV) can truly be a life saving procedure. It is a fast, effective way of providing oxygen to a patient with an obstructed airway who does not respond to more conventional means of opening the airway. The “can’t intubate-can’t ventilate” scenario is a good example. PCJV is faster to perform than a surgical airway. It will buy you time to establish a more permanent airway such as an intubation or surgical airway if the patient is hypoxic.
However, percutaneous transtracheal jet ventilation carries some rare though potentially serious risks of worsening airway obstruction and cardiovascular collapse if the catheter is not correctly positioned within the trachea. Fear may prevent us from using it. In addition, most of us have never had to use PCJV in an emergency or even seen it used. Lack of familiarity with the equipment and simple lack of comfort may make us hesitate to try. We may not even think about it in the moment of crisis. So let’s look at some of the ways we can use PCJV safely. Continue reading →
Laryngospasm is one of the more frightening events in anesthesia: the protective, reflex, spasmodic closure of the vocal cords that occurs when the vocal cords are stimulated. When laryngospasm occurs, vocal cord closure can be so forceful that it can prevent all ventilation or even the passage of the endotracheal tube. Life-threatening hypoxia can quickly follow. Other potential complications include post obstructive pulmonary edema, and possibly even cardiac arrest.
