Inserting a supraglottic airway is a component of all modern algorithms for difficult airway scenarios. I prefer to use the ILMA. It’s rigid stem allows for efficient manual probing for the optimal position. Furthermore is is designed to allow blind intubation after temporarily securing the airway with it’s LMA-functionality.
For an airway rescue technique, I try not to put all my trust into fiberoptics as failed intubations often are messy affairs with blood, vomit and secretions making fiberoptic techniques unrealistic. Blind intubations is an absolutely necessary skill for all of us dealing in difficult airways.
For those cases ILMA is likely to be the safest and best tool in the shed. Just look at the mini-review below of studies comparing ILMA with other airway devices designed to be intubated through. I found the table in this article reviewing SAD history, use and misuse. It is a good read and we will probably rip more stuff from it.
Here’s a good instructional video on how to use the ILMA:
And there’s more. It can be used for awake intubations. Check out these bad boys:
