as an anesthesiologist my most worrisome cases are those with no airway. I can relax and breathe a little if I have an airway. I can tell you with 100% confidence, I would absolutely hate doing and managing sedation all day every day. I'm almost 100% sure I'd find myself talking people out of it. There's just too much risk, unless the patient is still talking/responsive. But people keeping calling moderate sedation that which I am almost sure is general anesthesia with no airway.
Also, we are talking about events that occur maybe 1/1000 or 1/10,000. Or less frequent. So to allude to it never happening to you, or it being perfectly safe for you or for an entire field, just tells me you probably haven't been doing it long enough, or on enough patients. But oral surgery isn't alone in this. I find my partners falling into the same mindset. X, Y, or Z is safe (even though it's not what I would do) because it's what they always do. Well, when we really get into conversation they've done that like 20 times. Or 50. And bad events in anesthesia are rare.
Anyway, just wanted to put that out there.
