Well, I'm an SRNA, not a CRNA, but since no one else has responded...
Anesthesia doesn't really seem like the adrenaline game, definitely much more of a thinking game. It's been described as 99%/1%. 99% routine and 1% sheer terror when something goes wrong. It's probably realistically more like 99.9% / 0.1%.
That being said, there are places you can up the ante, so to speak. Working a community hospital in the middle of nowhere where you are the only anesthesia provider in house (no MDA to belittle you, which to be fair, only happens in hospitals with poor cultures). There you could definitely be exposed to some serious business, getting the page in the middle of the night to help intubate the trauma in the ED and rush him to surgery to stabilize before they fly the patient out to a bigger hospital. Of course, you're also just as likely to get woken up to place an epidural in a pregnant lady or to not get paged at all.
Have you ever thought about Acute Care Nurse Practitioner with a focus on ICU? They place lines, intubate, all that nonsense, but still live in the ICU. They admit, round, transfer, discharge, etc. They are sort of like the PA's for Intensivists.
