Hypotensive Anesthesia. By depressing a patient's blood pressure to very low levels, anesthesiologists can lessen the amount of blood lost and give the surgeon an almost clear field in which to work. This is particularly useful in surgery on vessels that carry blood to the brain and in orthopedic operations like hip implants. The anesthesiologist anesthetizes the patient, then infuses a drug, usually nitroprusside, to dilate the blood vessels. This causes the pressure of blood against the vessel walls to drop from a normal reading of, say, 120/80 to as low as 65/50. The anesthesiologist must be careful...

Some people, like pilots, policemen and firemen, are clamoring for the surgery to pass required visual tests. Others are seeking it for reasons of vanity...
...onset of his first heart attack. Before Dr. Lear's death four years later, he was to suffer every indignity open to victims of cardiac disease. Worse, as a doctor he understood exactly what was happening to him, so that he was not even granted the anesthesia of ignorance...
