Unless it is abdominal surgery, there is generally no need for routine enema before operation, and facial plastic surgery is naturally unnecessary. But it must be remembered that if it is general anesthesia, water must be fasted in strict accordance with the requirements of surgeons and anesthesiologists before operation. Usually, the hospital will require absolute fasting and water deprivation for 8 to 12 hours. You must never feel indifferent and secretly eat because it is cosmetic surgery or minor surgery. The purpose of fasting water before operation is to avoid suffocation and death caused by aspiration of reflux after anesthesia. In particular, many grass-roots hospitals and specialized hospitals like to use intravenous anesthesia, and the rescue measures and experience are also insufficient, which can easily lead to tragedy! Usually, plastic surgery patients are the last to abstain from water according to the doctor's advice. This is a joke about your own life, so be careful!
