Is there anyone who is a CRNA and later became an anesthesiologist?

If you took the premed classes in college, then you can apply for med school. It's still 9 years - 4 years of med school and 5 more for the anesthesiology residency. You don't get out of any of that as a CRNA. If you didn't take premed, you need to that first. So doing CRNA first would be a complete waste of time, not to mention med schools do not like accepting applicants who trained as nurses - you took a spot in that program away from someone who actually wanted to be a nurse.

There are a few who have done that, but not many. The interesting thing about this, is that one nurse who went on to med school and went from CRNA to anesthesiologist said that she had no idea how much she didn't know as a CRNA. They think they are equal to us. We know that they are not. They just don't know what they don't know! The differences are immense. Don't underestimate the education that physicians receive. A fully trained CRNA does not have the education to even apply to medical school. A new CRNA has done fewer cases than a first year anesthesia resident, and we consider them to still be a bit dangerous. I can't understand how it's OK to let a very inexperienced nurse be left alone with patients, but they do it. I used to work in a facility that started a nurse anesthetist training program. The things I saw, and the attitudes that I encountered scared the crap out of me. I no longer work there, and am now in a position where I do all my own cases, and do not supervise nurses at all. I know the care my patients get is much much better. I know a handful of very good CRNAs, that I would trust to take care of me or my family (under the direction of an anesthesiologist), but I know a lot more that I wouldn't let touch me or anyone I cared about. If you want to be a physician, then do it. If you want to be a nurse, that's fine too, but it's not a stepping stone to being a doctor. In fact, it's a bit of an obstacle. You'd have to unlearn the nursing mindset. You'e also taken a nursing spot from someone who wants to be a nurse. If you have what it takes to be a doctor, then you'd probably not be happy as a nurse. Physicians have a lot more responsibility, a much broader and more in-depth education, and a much more rigorous training program. It shows in how we care for patients.
