We frequently get called for difficult airways.
Last week, I had an ED call from anesthesia for an 8 month old that had significant biphasic stidor, severely increased work of breathing and was tiring out. Took him to the OR for intubation, which anesthesia defered to us, and formal arway evaluation.
Nearly all of our radiated head and neck cancer patients are difficult airways, due to radiation effects on mouth opening (trismus) and inability to extend their necks. We often obtain the airway for our anesthesia colleagues.
Yes, we rarely show up for codes - anesthesia is obviously very good at obtaining an airway, and have their own algorithms for a difficult airway (masking, LMA, etc) that can adequately ventilate a patient until they can call us, if needed.
At my insttution, general surgeons rarely do open trachs. They perform percutaneous trachs the vast majority of the time, and, indeed, recently had a chief GS resident ask if they could scrub a few trachs to get the experience before they graduate. Last year, GS nearly lost a patient on the table whle performing a trach when they hit the innominate.
Also, although we usually act as technitions when performing trachs for off-service patients (ie MICU patients), the critical care doctors choose ENT surgeons for their patients since we provide a "service" rather than just an operation - I can't tell you how any consults we've gotten for prevously placed perc trachs that they are unable to decannulate, and when we see the patient find the same cuffed trach place 6+ months ago (oftentimes still inflated) - no wonder they can't decannulate!
There are many areas where GS and ENT overlap within the neck - trachs, thyroids, neck dissections, etc. As long as they've received adequate training, both are equally qualified to perfom the operation. However, the ENT spends all of their time in the head and neck - and are far more comfortabl. An example would be thyroids, we both perform them at our institution. GS incisions are 10 cm. Ours are routinely 4 cm, and can be as little as 2.5 cm (with endoscopic assistance) - if you were referring your 29 y/o female for throidectomy, who would you choose?
