In the United States, anesthesiologists have the highest salaries of all doctors, and there were once many people who thought that anesthesiologists’ job was just to give patients a shot and let them sleep, so how could they be paid the highest salary in the U.S. medical industry? Salary should be reduced. So the United States held a televised debate, when the vast majority of guests overwhelmingly one-sided support for anesthesiologists to reduce their salaries. But the anesthesiologist who attended the debate said this on the spot: “In fact, I give this injection free of charge, and the fees I charge and the salary I get are just to watch the patients after the injection, not to let them die because of anesthesia accidents or surgical hemorrhage, and to make sure that they can wake up safely after the operation. If you think I’m overpaid, that’s fine, I’ll just give the shot and leave.” “Since then there has been no more debate in America about whether anesthesiologists are paid too much, because human life is above all else, and everyone has learned the important role anesthesiologists play in preserving life.” What exactly is anesthesia?
