The world of surgery in prior to the 1900's was primitive by our standards. Although Fracastoro of Verona in 1546 theorized that small germs could cause contagious diseases, no one associated them with wound infections. Bed linen and laboratory coats were not routinely washed, and surgical instruments were only cleaned before they were put away for storage. The same probe was used for the wounds of all patients during rounds to look for pockets of undrained pus. Pain and pus were considered ...
