You are in control of the patient in the OR, but nearly all of the time, it's of stable pts, which sounds like it might be boring to you. No one wants instability or crashing pts in the OR. You sound like you love that aspect of the ED.
I think you would like ACNP, actually, if you found the right hospital. My level 1 trauma center is an academic medical center, and in the trauma ICU, the NPs run the show. They outrank all the residents a far as getting to choose what to do with the pts if there's a disagreement between them. I can't tell you how many lines and intubations I've seen them do (it's all the time). They are a resource for the nurses on staff and the residents. During rounds, they have their own pts assigned to them, just like the residents do. Everyone reports to the attending during rounds, but that's just for collaboration purposes.
So I think maybe this aspect you'd love, getting to be a provider in a fast-paced setting. Not a CRNA that sits on their rear end for 8 hours of a low-key case. Even trauma surgery isn't crazy in the OR all the time. And you have to stay there after the procedure is over, while they close, etc.
So maybe take another look at NP at other facilities? You can also shadow NPs. You'd hate to spend all that time and effort on CRNA just to hate it. And if you still want to pursue CRNA, I'd most definitely recommend shadowing a lot of hours, and stick with one single CRNA in their entire set of scheduled cases, not bouncing around. You need to watch what one actually does, from the start of their day to the end of it, in real life day-to-day. If you can't stand days like that, you can't make it your career.
Anyway, just my two cents.
