Pre-operative preparation for minimally invasive breast surgery: 1. Avoid menstrual period. 2.Check blood routine and clotting time. 3. Urination before surgery. Generally for surgery, a meticulous examination and diagnosis of the disease should be performed before surgery to avoid irreparable damage to the patient. Before surgery, there should also be sufficient understanding of the patient’s general condition and estimation of the patient’s surgical tolerance. Detailed medical history, comprehensive physical examination, and routine laboratory tests should be performed. From the point of view of the patient’s tolerance for surgery, there are two categories: The first category, good tolerance, means that the patient’s general condition is good and the surgery can be performed after general preoperative preparation. The second category, poor tolerance, refers to the patient’s poor general condition and requires active and careful special preoperative preparation before surgery can be performed. The preoperative preparation mainly includes both psychological and physical preparation. ①Psychological preparation: The attending physician should clearly explain the diagnosis of the disease, surgical methods, possible complications, preventive measures, as well as the postoperative recovery process and prognosis. Patients and their families should also ask the attending physician about their concerns regarding minimally invasive breast surgery and prognosis without reservation, and get an explanation from the attending physician so that they can be more fully prepared for the surgery. ②Physiological preparation: It mainly refers to the preparation of maintaining the patient’s physiological state so that the patient can safely go through the surgery in a better condition.
