Due to the characteristics of the anesthesiology department’s work nature (closed to do things, and contact with patients is limited to a short period of time in the operating room), many people (including the general patients, many leaders of hospitals, and some medical staff in hospitals) know little or even close to nothing about the nature of its work and its work characteristics. In some hospitals, anesthesiology is even classified as a medical technology department, which has become a laughing stock in the industry. In the eyes of many people, anesthesia is just “giving a shot”, and there is a serious lack of anesthesia knowledge. In fact, in surgery, the surgeon focuses on a patient’s lesion, while the anesthesiologist sees the patient’s whole body, in addition to ensuring that the patient’s anesthesia effect is perfect, but also to make the patient comfortable. What is more important is to monitor the patient’s vital signs, such as whether the blood pressure is stable, whether there is hypoxia and carbon dioxide storage, how much intraoperative bleeding, the need for timely replenishment of various types of fluids (crystalloid or colloidal fluid or plasma or red blood cell suspension or component blood transfusion) and so on all kinds of conditions, to fully protect the patient’s safety, with the industry in the words of “the surgeon is in charge of the disease, the anesthesiologist is in charge of life”. The importance of the anesthesiologist can be seen from the saying in the profession that “the surgeon is in charge of the disease and the anesthesiologist is in charge of the life”.
