Hi there-Modern anesthesia techniques have evolved remarkably over time, and generally speaking, even people with significant illnesses are able to undergo anesthesia safely.The relative safety of your particular anesthesia experience is going to depend on many different variables that only your surgeon and his/her chosen anesthesia provider can help you understand, such as your overall state of health, the type of anesthesia they are planning for you and the medications chosen, and the length of the operation.Having said all of that, if you have chosen a Board Certified Plastic Surgeon, and the procedure is to be performed at an accredited facility, with an anesthesia provider that is also Board Certified in their specialty, it is exceedingly unlikely that they would allow you to proceed with what is fundamentally an elective procedure if they believe you are at significant risk of not waking up after the surgery. These are common concerns, and they are understandable, but if you are healthy enough to have the operation (and are having it under the circumstances described above), these types of catastrophic outcomes should be exceedingly rare.I would also review this with your surgeon, who is in the best position to put you at ease.
