To expand on Tim's comments, the I-LMA has been used 8 or 9 times since it was first stocked on our aircraft for failed airways. Our vast success with its use is promising for intubating LMA's as a secondary airway in face of failed intubation. While endotracheal intubation via direct laryngoscopy is our primary method of securing an airway, our staff are comfortable and reassured with the I-LMA should they experience a difficult airway.
Coincidently, our medical director at MedCenter Air is conducting a multiagency study on the use of the Intubating LMA. A protocol is set up ( I know at least with our agency) and states that direct laryngoscopy will be the primary method for intubation. The I-LMA is utilized in the event of a failed airway. Finally, our competency on it's use is maintained through quarterly skill practice.
