Preoperative preparation for gallbladder stones includes preparation of the surgical site, dietary preparation and medication preparation. 1. Surgical site preparation: Usually, it is necessary to clean the surgical incision to reduce bacterial colonization, and if the body hair is strong, it is also necessary to prepare the skin locally, so as to reduce the rate of surgical infection. 2. Dietary preparation: gallbladder stone surgery is usually performed under general anesthesia, and it is often necessary to abstain from drinking and eating for a certain period of time before surgery to avoid any reaction such as aspiration and vomiting after anesthesia. 3. Drug preparation: If you are not allowed to drink or eat before the operation, you often need to use drugs such as glucose under the guidance of the doctor to supply energy to the body, so that the body can tolerate the operation. Modern perioperative management of surgery advocates multi-modality and individualization, and should be carried out under the guidance of professional doctors.
