It is generally accepted that patients should have nothing to eat or drink (referred to as “NPO”) after midnight on the evening prior to surgery. Exceptions to this rule are rare and should be discussed with your anesthesiologist. Infants who are breast feeding may have breast milk until four hours prior to surgery or infant formula until six hours before surgery. Although clear liquids may be allowed closer to the time of surgery, in the even that your surgeon is ahead of schedule, drinking could unnecessarily delay your procedure. It is often a good idea to stay well hydrated on the day prior to your surgery and avoid alcoholic beverages.
