How important is the anesthesiologist during the operation?

Generally speaking, the ability to control the circulation and respiratory system reflects the level of anesthesiologists. In short, the level of anesthesiologists who can anesthetize heart surgery and esophageal cancer and lung cancer surgery (esophageal cancer is mostly suffered by the elderly and lung function is poor) is reliable. As a surgeon, it is definitely a happy thing to cooperate with a high-level anesthesiologist. Imagine, in the case of great trauma and stimulation to the human body, keeping the body function stable, just like going to the middle of the next chess game, is a superb technology, even art. The connotation and extension of modern anesthesia are very wide, and first aid, intensive care, cardiopulmonary bypass and perfusion, pain and so on are still in the rapid development stage.
