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.

As you read this I am flying to Honduras with International Relief Team on a head and neck surgery medical mission. I will attempt to post mission updates from the hospital compound, pending internet connections. Participating in a medical mission to the developing world is never easy.
Medical personnel trained in a high tech environment take for granted the complex monitoring devices, multiple choices of drugs, and plentiful support peronnel which simplify our job. When medical volunteers travel to the developing world they are often unprepared for the potential hazards produced by outdated technology, unfamiliar and sometimes poorly maintained equipment, poor sanitation, limited supplies, and a malnourished, often poorly educated population.
Let me give you an example of one rather exciting case from early in my volunteer experience. 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 →
Deciding when to extubate a patient safely can sometimes be a difficult decision.
We all know the common criteria for extubation:
recovery of airway reflexes and response to command;
inspiratory capacity of at least 15 ml/kg;
no hypoxia, hypercarbia, or major acid/base imbalance;
no cardiopulmonary instability;
signs of intact muscle power;
absence of retraction during spontaneous respiration;
absence of a distended stomach.
In other words, you want your patient to be stable, able to breathe without help, and able to protect the airway.
However, sometimes the decision is not so easy. Here I describe a case of a patient who met some but not all of the criteria for extubation. The reason turned out to be due to a rare complication: plugging of the endotracheal tube. However, getting to that solution required working through the extubation algorithm. Continue reading →
Tongue necrosis is fortunately an extremely rare complication of endotracheal intubation, but the injury can be devastating. It’s important to recognize the patients at risk and to take precautions when securing an endotracheal tube to decrease the risk of injury.
I saw this injury myself many years ago. I was called to the ICU to evaluate a patient for postoperative tongue pain. The patient was an otherwise healthy 41 year old who had undergone cervical spine decompression for tumor two days before. The patient had been in the prone, head flexed position in tongs during a surgery that had lasted about 7 hours. About 2 liters of crystalloid had been given and blood loss was less than 200 ml. Surgery had been successful and the patient had been extubated at the end of the case neurologically intact.
When the patient started talking to me, speech was terribly slurred. Almost the entire right side of the tongue was a pale brown and gray color, firm, and markedly edematous with an ulceration. Tongue necrosis was diagnosed. I don’t have a picture for this patient, but this photo, taken from an excellent review of tongue necrosis, is similar.

During the case, since neurostimulation was to be used to monitor spinal cord function, two fairly large, soft bite blocks made of rolled gauze had been placed to prevent the patient from chewing the tongue or mouth when stimulated. At the end of the case, the anesthesia team noted that the tongue looked a little swollen and that the tube had left an imprint over the back of the tongue. Continue reading →
