There are a few steps that patients need to take prior to I.V. anesthesia. First, you should not eat or drink anything at least 8 hours prior to surgery and refrain from smoking 12 hours prior to surgery. You will need someone to accompany you to the surgery 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 prior to surgery. Other than these simple considerations, there is nothing else you need to do to prepare for surgery.
