The first modern operating room in America

The modern OR was a vital addition to aseptic technique and essential to the development of invasive surgery, and many people do not realize that it needed to be "invented." Gustav Neuber, William S. Halsted, Charles McBurney, and others pioneered the necessary changes in practices and the environment to protect the patient from infection. This article presents the history behind the evolvement of the modern OR and discusses changes in the structures of some facilities as awareness increased about the principles of asepsis.
