A French article published Feb 2011 in Annales Françaises d’Anesthésie et de Réanimation looks at adherence to difficult airway algorithms. The authors look at the descision-making involved in a can’t intubate can’t ventilate (CICV) training scenario when they should be abandoning laryngoscopy in favour of a surgical airway. And that decision seems to be a difficult one.
This article demonstrate how, in a training scenario, 10 of 24 emergency physicians needed a hypoxic cardiac arrest as a hint before actually proceeding to an emergency surgical airway.
14 of 24 correctly proceeded to a surgical airway in the 2 minute window given from when ventilation became impossible to the hypoxic arrest.
They were all trained emergency physicians who knew what they were supposed to do in a CICV situation. And this was just a training scenario. Still, almost half of them failed to act when shit hit the fan. It shows the importance of being prepared for those quite rare, but quickly fatal events that can occur in our line of work. You need to not only think through the events briefly, but to play them out in your personal simulator – your mind. Not just go through the steps in a broad sense, but go through every detail of the event and procedure. When to intervene, where to get the necessary equipment, what to do. Visualise the whole thing. So if something like this ever happens, you’ll be prepared, and you will act.
