Ive only done three in my career, one was for a closed up airway with massive edema secondary to a thermal burn, the other two were for facial trauma. A lot of services are having success with the QuickTrach systems. I haven't used one yet but they might be a good compromise for those services that are hesitant about full on surgical crics but realize the many and inherent limitations of needle crics.
The only danger is if you have that "skill" in your pocket, is its overuse. I've QA'd and seen many cases of over zealous crics both by prehospital and hospital providers. It truly is a LAST RESORT. With rescue airways like LMAs/Kings/Combi's we really should not be cricing more than a handful of times during a career in a busy system.
