I will be undergoing rhinoplasty soon and am unsure whether I want to be out under General Anaesthesia or Twilight Sedation. I don't want to wake up or be conscious during the surgery so GA may be the better option however I am concerned about the risks that come with GA. I have high cholesterol and my chest/heart area often feels tight so I'm worried about the risks of GA. Does having high cholesterol increase the risks of GA?
