CRNAs are the only type of non-physician anesthesia provider that have successfully lobbied for the ability to provide all types of anesthesia for any surgery or procedure independently in some states. AAs must work under the supervision of an anesthesiologist, and dental anesthesiologists are limited to dental cases.
