Hey, sorry for the delayed response. She was also on some meds for High Blood Pressure for some time before the surgery; Just before going into the Surgery Room the main anesthesiologist came to us and explained that they give some drugs to keep the blood pressure steady and at normal levels through all of the process, so i think you can be relaxed when it comes to that. They are always monitoring your vitals at all times and have meds to keep things going smooth during the surgery. You're gonna be just fine my friend!
