For 10 days prior to surgery, patients must not take aspirin, any aspirin containing drugs, related drugs such as ibuprofen (Advil, Motrin) or naproxen (Naprosyn), or Vitamin E. These drugs can increase the risk of bleeding. The evening before surgery, patients should wash their head, neck, and chest with hibiclens (or other soap containing chlorhexidine) in the shower. The morning of surgery, the patient should not take their antiparkinsonian medications. However, the patient should take any medications they normally take for other problems, such as high blood pressure. Patients should inform the surgeon if they develop a cold, cough, or any type of infection in the days prior to the surgery. Patients should be well hydrated (drink a lot of non-alcoholic, non-caffeinated drinks) prior to surgery.
