Environmental Assessment of the Surgical Center for Eight Years

Abstract

Airbone particles and airbone bacteria were checked and the number of organisms on the surface of the floor and wall in the operating room were counted every year for the eight years since the openning.Numbers of airbone particle and airbone bacteria for the latter half of the eight years were fewer than those for the first half of the period, because of additional several counterplans to maintain the iperating envitonment to be clean. Number of bacteria on the surface of floor in the operating room showed the same tendency.Necessity of environmental assessment in the operating room and permitted grade of contamination of the operating room were disscussed.
