Whether it is surgery or anesthesia, it is extremely primitive. With the development of surgery and anesthesia in recent 50 years, surgery has become a routine medical means that most people can tolerate, and various organ transplants, cardiovascular and neurosurgical operations can be safely carried out.

Is an anesthesiologist important? For patients undergoing surgery, the most urgent expectation is safety and painless. For surgeons, stable and good surgical conditions are needed. The importance of anesthesiologists is actually proportional to the scale and level of medical institutions. The bigger the hospital, the more severe patients there are, and the more important the anesthesiology department is. On the other hand, without a good anesthesiology department, the level of the hospital will not be too high, at least in layman's terms, high-level critical first aid and surgery cannot be carried out. A good hospital is inseparable from a good anesthesiology department.

It is not so much how important the anesthesiologist is in the operation as what role the anesthesiologist plays in the whole perioperative period from preoperative to postoperative.

1. preoperative evaluation and treatment: surgery is always a major trauma to the human body. Life is a long run, and surgery and trauma are particularly difficult episodes. Whether the human body can withstand the blow. The preoperative cardiopulmonary function reserve, basic diseases and abnormalities that need to be corrected all depend on the clinical diagnosis, evaluation and treatment of anesthesiologists.

2. Intraoperative anesthesia and support: For any kind of operation, the safety of patients and pain relief are the basic requirements of anesthesia. For those patients with major operations and poor conditions, the monitoring and treatment of anesthesiologists are maintaining the lives of patients who may be lost every minute. Anesthesia maintains the highest doctor-patient ratio among all medical specialties. A patient's operation needs the constant care of at least two anesthesiologists or nurses, because even the simplest operation may be dangerous at any time.

3. Postoperative care: Today's anesthesia has gone beyond intraoperative management and covered a series of postoperative support. Critical care medicine was originally established under the leadership of anesthesiology around surgical problems such as surgery and trauma. Of course, today's intensive care has gone far beyond the original scope.

4. Pain treatment: Modern anesthesia and pain treatment have expanded from initial trauma and surgical analgesia to an independent discipline independent of traditional internal surgery. All acute and chronic pains (traumatic pain, lumbocrural pain, neuralgia, tumor pain, central pain) belong to the professional category of pain department. Only in China, this is a new thing.

In addition to these more or less well-known responsibilities of anesthesiologists, in fact, each of us has dealt with anesthesiology from birth to the end of our lives. Everyone born in modern hospitals has Apgar score at birth, including skin color, heart rate, breathing, muscle tension, exercise, reflex and other items. With this scoring standard, the medical quality of newborns before and after birth has been effectively improved. Many people think that this scoring system was invented by obstetricians and gynecologists. Actually, it is the masterpiece of American anesthesiologist apgar. Ordinary people are gradually becoming familiar with the rescue of "artificial respiration and chest compressions", whose real name is cardiopulmonary resuscitation (CPR), which is a great creation of life-saving initiated by anesthesiologists such as Peter Seifer. These are the important contributions of anesthesiologists and anesthesiologists to modern medicine.
