I use the interview as an extension of the anesthetic, if needed. That is, the preop is the premed. Some patients don't want to hear any of it and just want to get it over with, in which case I cut to the chase, do a cursory airway exam if the chin looks a little short or the neck a little fluffy, and be on my way. Risk discussion depending on procedure.
For those who are clearly scared shiteless, I spend a few extra minutes going over any concerns and reassuring them. Some people have a bazillion questions, and I feel it's fine to slow things down for them so that they feel they've been heard out.
I haven't put a stethoscope on a chest in quite some time. But we have a VScan, so if I'm at all concerned about the heart, or the patient is sick and hasn't been out of bed in months, I slap that on as my stethoscope if there's no recent echo. If anything is truly concerning, there is a real echo machine down the hall and I'll do a more formal echo myself including Doppler of the aortic valve, TR looking at PA pressures, etc. Also get to see the volume status before going in. Takes 5 minutes at most, and no need to cancel cases for cards workups just because someone heard a murmur. Show me a CRNA that can do that.
