1, internal medicine is generally treated with drugs, and surgery is generally treated with surgery. Non-mechanical injury of thoracic and abdominal organs should be found in internal medicine; Mechanical injury of muscles, bones and ligaments, wound infection, seeking surgery. Some surgical diseases do not develop to a certain extent and do not need surgical treatment, and some internal medical diseases can also become surgical diseases with the progress of the course. Pay attention to medical treatment in time. Historically, the earliest surgery can only deal with some external diseases, such as some common furuncle, carbuncle, skin lump and some simple operations, so it was called surgery in ancient China. Of course, there are legends in history. Huatuo used Mafeisan to anesthetize patients for craniotomy. This is just a legend. From the perspective of modern medicine, it is impossible. First of all, the understanding of anatomy in that era was far from enough, and then there was aseptic operation and infection. In the west, the same is true of the development of early surgery. In the west four or five hundred years ago, surgery was not a special profession at all, but a barber acted as an agent and could only deal with some simple skin surface problems. Of course, with the development of western anatomy, anesthesiology, chemistry and microbiology, surgery has gradually matured in western medicine. SURGERY, the English word for surgery, means "hand technique". It shows that an important feature of surgery is hands-on operation. Of course, with the development of modern medicine, the boundary between internal medicine and surgery has become increasingly blurred, and there have been many intersections. At present, the classification is as follows: all diseases that need surgical treatment are classified as surgery, and all diseases that do not need surgical treatment are classified as internal medicine. Of course, there are also many diseases that need consultation in different departments at different times, such as coronary heart disease. Some people can solve the problem by taking medicine, some people need interventional therapy, and some people need surgery. Therefore, this requires cooperation between departments and mutual understanding and learning. The interventional therapy mentioned here is actually an interdisciplinary subject between internal medicine, surgery and radiology. At present, some medicine has special interventional departments, some belong to a subgroup of radiology, some belong to internal medicine, such as cardiac intervention, and some belong to surgery, such as neurointerventional therapy. This division is not clearly defined, but gradually formed according to the habits of different hospitals in different countries and regions. Internal medicine is generally divided into: cardiology, neurology, respiratory medicine, gastroenterology, nephrology, endocrinology and rheumatism; Surgery is divided into: cardiothoracic surgery (some hospitals are divided into thoracic surgery and cardiac surgery), neurosurgery, general surgery (including abdominal surgery, breast surgery, thyroid surgery and vascular surgery), urology, orthopedics, burn plastic surgery and pediatric surgery (also in the category of pediatrics). In essence, although both internal medicine and surgery belong to the category of medicine, even though they have so many similarities, their work nature and the thinking mode of internal surgeons are quite different. As a systematic discipline, internal medicine has a complete theoretical system, although it is practical. It studies the human body as an independent system. Because of the intervention of human factors, surgery should think of the human body as an open system more often. If a physician is called "home", then a surgeon is a "craftsman". However, if a doctor just closes the door and doesn't do clinical work, he will never become a real "doctor"; Similarly, if a surgeon only studies how to make the operation beautiful and perfect, but ignores the study and induction of theory, he will never become a "skilled craftsman." Perhaps the nature of work is different, and the external temperament of doctors at home and abroad is also different. Surgical work requires doctors to be firm, bold, cautious, decisive, crisp, calm and orderly. Internal medicine requires doctors to be thoughtful, knowledgeable and meticulous. Female students who graduated from medical college generally aspire to do internal medicine work, because internal medicine work needs more patience and meticulousness. Male students all aspire to do surgical work, because surgical work is more challenging, more fulfilling and more attractive. The operation works like this. With the operation, everyone wants to do it, even if the operation process is very tired, they have to take risks. But when arranging the operation, everyone wants to go on stage as much as possible. I think maybe there are not many professions in the world that regard work as happiness and honor like surgery. Perhaps it is this nature of work that attracts many people with lofty ideals to devote themselves to this cause without pay, work hard and have fun in hardships. 2.
