1. If your cutoff for food and water is at midnight, drink plenty of clear fluids (not alcohol) during the evening until then. If you’re well-hydrated, you’ll feel better and your veins will be fully dilated-and more receptive to IV fluids and drugs.
2. Inform your doctor about any supplements you take. About 70 percent of surgery patients don’t think to do so, but it’s important. Fish oil can increase bleeding, while others, such as kava and St. John’s – wort, may prolong the effects of anesthesia.
3. Shower the night before and the morning of your surgery with anti-bacterial soap, or, even better, use a special wash, like Hibiclens, which kills germs on contact and helps protect your skin for the next 24 hours.
4. Be patient as everyone you meet asks your name and what procedure you’re having done on which body part. Also have someone act as your second eyes, ears, and voice. Write down your medications and medical history beforehand in case you forget.
5. Accept the blanket offered in pre-op. Several studies show that staying warm can lower your risk of Infection.
