Even though they do a lot of things during a surgery, most people think that all they do is put people to sleep right before the real doctors come. In reality, they have a much more complicated job. When they do give people anesthetics they have to exactly where and how to give it to the patient. They also need to know how much of what kind of anesthetics is needed for every type of patient. Besides giving anesthetics, they also do things during the surgery.
Anesthesiologists do all the work behind the surgery.
They make sure that the patient is breathing right and that the heart is beating correctly. They also check the blood pressure of the patient behind the scenes of the surgery. Even after the surgery the Anesthesiologist has to be with the patient in the extensive care unit. There they monitor the patient until the patient is well enough to leave the extensive care unit. In order to do this job you must be very good with your hands and your hand-eye coordination.
