I had the opportunity to use the Airtraq - a potentially difficult airway - obese endstage liver and renal dz. Intubation was very smooth, quick visualization.
Couldn't visualize with either mac or miller [blade] attempts. I got an Airtraq from my locker and a novice used it and it passed what I call the "oh wow" test.
Difficult airway was intubated originally with an intubating LMA after DL failed. The ET tube has a cuff leak and the patient developed sepsis, plus had 10 liters of fluid onboard. Head and neck bloated. So used the AIRTRAQ to go in around the old ET tube, inserted a yellow Cook tube exchanger, removed old ET tube, inserted a new ET tube.
