I have already answered this concern in another question your asked, but you obviously are concerned about anesthesia, as are many patients.
As a plastic surgeon who performs totally-elective cosmetic operations for my patients, I am acutely aware that what I do for my patients falls in the "want-to" rather than the "have-to" category, so the anesthesia and the operation BOTH need to be as safe and predictable as possible. In our nationally-accredited (AAAASF) on-site surgical facility we have offered fulll anesthesia services for over two decades, and we have performed over 16,000 operations with no deaths, heart attacks, or strokes. So we're good, and safe, and not perfect--we have to be thorough, and safe, and careful EVERY time. EVERY patient. That is true for the vast majority of ABPS-certified plastic surgeons who operate in their own nationally-accredited facilities, or at similarly-accredited hospitals or surgicenters.
I believe you should check out your anesthesia provider as well as your surgeon--make sure you have a Board-certified MD anesthesiologist or a fully-accredited CRNA (Certified Registered Nurse Anesthetist) with experience in office-based outpatient plastic surgical procedures.
I also believe that TIVA is superior to hospital-type inhalation anesthesia, which is why this is the preferred anesthetic regimen in our facility. For more information on this, click on the web reference link below.
I also believe that having your anesthesia provider actually stay in the operating room during your procedure (not "supervising" from another room like the doctor's lounge) is critical to you having the best and safest anesthesia experience. Often, hospital-based plastic surgeons will often have MDAs who leave the OR during the case and "supervise" the CRNA or Anesthesia Aide who is actually doing your anesthesia. After all, you are young and your surgery is elective, so they "justify" being present in another OR where the patient is sicker, older, or more at-risk. Or that being "available in the doctor's lounge" is OK. Ask your anesthesia provider if they will be present in your operating room for the ENTIRE CASE. Ask if they are "covering" more than one case at the time your surgery is going on.
I tell you this not to add to your worries, but to ensure that you have all the information needed to make your own anesthetic as safe as humanly possible, which is indeed less risky than your automobile ride to the facility! Best wishes! Dr. Tholen
