The word anesthesia is derived from the Greek word narkosis, which, as the name suggests, means numbness and paralysis, and drunkenness and stupor. Therefore, the meaning of anesthesia is to use drugs or other methods to make the patient temporarily lose sensation as a whole or locally, in order to achieve the purpose of painless surgical treatment. Anesthesiology is a science that applies basic theories, clinical knowledge and techniques about anesthesia to eliminate patients’ surgical pain, ensure patients’ safety and create good conditions for surgery. Nowadays, anesthesiology has become a specialized independent discipline in clinical medicine, mainly including clinical anesthesiology, emergency resuscitation medicine, critical care monitoring and treatment, pain diagnosis and treatment, and other related medicine and its mechanism, which is a comprehensive discipline to study anesthesiology, analgesia, emergency resuscitation and critical care medicine. Clinical anesthesia is the main part of modern anesthesiology. Human is a complex organism, and sick people add more variables to this complex organism. Although medicine has advanced considerably, there are still too many unanswered questions that remain unanswered. More of our medical treatment is still limited to symptomatic treatment. Surgery is a necessary part of the treatment, but the whole process does put the patient in a very dangerous situation. The patient’s own fears and the family’s worries are well justified. In order to do the best possible job of keeping the patient safe and pain-free, anesthesia becomes a critical step in the success of the procedure. Such an important prerequisite makes a pre-operative anesthesia signature necessary. Medicine is one of the sciences where the natural sciences and the humanities are most tightly integrated. When a person loses his health, he shows more hope and helplessness to the public factor, similarly, the doctor also hopes to give more understanding to some kind of powerlessness. In fact, the process of signing is the process of mutual understanding between doctor and patient. When signing before anesthesia, the anesthesiologist will try to explain the advantages and disadvantages of anesthesia, some factors may be difficult to control but will try their best. This is in line with a scientific approach to natural science. The patient’s family can ask questions and make requests through the signing process to find the best fit between the two parties. In general, a full understanding from the patient’s side tends to free the anesthesiologist’s mind for higher potential. A little more clarification and explanation from the anesthesiologist will make the patient feel more comfortable. Due to the current workload, overly concise and rushed verbal communication is often a source of misunderstanding, and we are working to improve this.
