"Nineteenth-century operating "theaters" had more to do with medical instruction than with saving patients' lives. If you could, you stayed out of them at all cost. For one thing, you were being operated on without anesthesia. (The first operations under ether didn't take place until 1846.) Surgical patients in the late 1700s and early 1800s could feel every cut, stitch, and probing finger. They were often blindfolded--this may have been optional, not unlike the firing squad hood--and invariably bound to the operating table to keep them from writhing and flinching or, quite possibly, leaping from the table and fleeing into the street. (Perhaps owing to the presence of an audience, patients underwent surgery with most of their clothes on.)"
