I had surgery under what was supposed to be general anesthesia; I told the surgeon that I wanted a board-certified anesthesiologist and she agreed. But I ended up with a nurse (CRNA) who was so unskilled and negligent that she let the sevo vaporizer run dry and I was paralyzed but awake/aware for 10 minutes. Horrible pain, unable to scream. The trend today is to use nurses (CRNA's) not anesthesiologists and they just don't have the skill set to do general anesthesia. I'm a physician and if this could happen tome, it can happen to you. Don't believe the BS that the "CRNA's are supervised by MD's"; they really aren't. Despite my experience and medical degree, I'll never trust anesthesia again; if they promised me an ansethesiologist and delivered a nurse, that's fraud. And the icing on the cake is that the CRNA tried to lie about what happened to me; that is until she found out that I was a physician. Nurses have a place in the O.R., but delivering anesthesia is best done by an anesthesiologist.
