If your procedure requires anesthesia, your anesthesia will be provided by an anesthesiologist or a certified registered nurse anesthetist (CRNA). The appropriate type of anesthesia will be determined by your physician in consultation with the anesthesiologist/CRNA and with your approval. Your anesthesiologist/CRNA will answer any of your questions or concerns before the surgery. Even though it is noted in your patient chart, please be sure to inform the anesthesiologist/CRNA if you have taken any medications including over the counter drugs and vitamins, as well as any allergies you may have to medications.
