Is a nurse anesthetist, to assist gi during a screening colonoscopy, a good choice over an anesthesiologist?

Health care provider: A nurse anesthetist also referred to as a crna is qualified to provide anesthesia for just about any procedure as well as being able to manage difficult airways in an emergency.

Anesthesiologist: A nurse anesthetist (crna) is a cheaper, less trained alternative to an anesthesiologist. The md is likely the better option. There are always bad mds and there are some phenomenal crnas but your safest bet would typically be the more extensively trained md. That being said, most anesthetics are safe, and you will likely be fine, but colonoscopies have ended in deaths like any other procedure.
