You ask a very good question and I think one that at times inspires its fair share of debates. I can happily offer you my opinion on this matter.A CRNA is a highly trained clinician who must complete a multi-year training program that includes many (NOT ALL) of the same courses that medical students take during medical school. CRNA students then enter an 18+ month "residency" of sorts where they are actively running surgical cases in the operating room, performing the majority of the same tasks as an anesthesiologist such as intubation, monitoring vital signs, fluid administration, and the administration of inhaled anesthetic. They are evaluated and must pass classroom and clinical exams prior to graduation. They take their jobs very seriously and perform their jobs safely and admirably.However, it is important to realize that in the vast majority of US states (I am not sure about Florida), CRNAs MUST practice under the supervision of an anesthesiologist who is physically in the hospital at all times and in the operating room with them at the most important times (you going to sleep and you waking up). The anesthesiologist is immediately available at all times, and many times they stay in the room with the CRNA during the entire surgery. The anesthesiologist is responsible for their actions, their decisions during the surgery, and most importantly -- YOU and your well-being.So you see, it is unlikely that you will need to be concerned that you will only be treated by a CRNA because by definition they are always supervised by an anesthesiologist. I have had CRNAs treat my patients for years now and I can confidently say they have always been more than capable to handle even the most difficult surgeries. Couple that with the knowledge that an anesthesiologist (an M.D. or D.O.) is also watching over you and you have a very safe surgery indeed. Think of it as 2 sets of eyes!Good luck with your tummy tuck, and best wishes!
