AA's are different, they are required to be directly supervised, whereas CRNA's are not. From the kentucky website: (d) Notwithstanding Section 9 of this administrative regulation, the physician assistant shall not administer or monitor general or regional anesthesia unless the supervising physician, who must be a board certified anesthesiologist, is physically present in the operating room during induction and emergence, and thereafter physically present in the operating suite and not concurrently performing any other clinical procedure.
This type of language is the same in every state in which AA's can practice. Read the scope for CRNA's there is a vast difference.
They do not learn how to perform regional anesthesia or insert invasive lines in school, although the anesthesiologist can teach them after they graduate.
There are many states that do not recognize AA's (they have no scope of practice), of the states that do recognize them, they are not usually classified as PA's.
At this point there are only two schools
. Although I think another one is opening in Louisianna.
CRNAs are licensed as advanced practice nurses in ALL states. The ASA will certainly allow any CRNA who wants to join, join as an associate member....all they have to do is give up their membership to the AANA. Of course doing that would be ridiculous, there are some issues where the two groups are at opposite ends of the pole.
Unlike the American Nurses Association the American Association of Nurse Anesthetists is a very proactive organization. The PAC for AANA is one of the most effective in the country.
