Surgical Wound EnvironmentRitter, Merrill, A.Clinical Orthopaedics and Related Research: November 1984 - Volume 190 - Issue - p 11–13 SECTION I: SYMPOSIUM: PDF Only Free Abstract Author InformationAuthors People are the major source of bacterial contamination in the hospital environment, and to control environmental bacteria, the shedding potential of people must be controlled. In a conventional operating room, the more complete the surgical attire worn by everyone in the room, the better the control; i.e., body exhaust equipment for the anesthesiologist and the scrub nurse is essential. The laminar airflow filter system and ultraviolet light are effective environmental controls for preventing wound contamination.
