There are a few steps that patients need to take before anesthesia. First, you should not eat or drink anything at least eight hours before surgery and refrain from smoking 12 hours before surgery. You will need someone to accompany you to the operation and drive you home after. On the day of surgery, do not wear any jewelry, contact lenses, or dentures. If you regularly take medications, discuss those with the doctor to ensure that they are approved before surgery. Other than these simple considerations, there is nothing else you need to do to prepare for surgery.
