title: [The importance of the airborne microorganisms evaluation in the operating rooms: the biological risk for health care workers].
abstract: The operating room is a complex environment, traditionally considered at high infectious risk, for both the patients and the health care workers, they can contract diseases, because of the exposure for relatively long times to various dangerous chemical, physical and biological factors. The biological contamination in the operating rooms is mostly imputable to airborne and bloodborne microorganisms, whose primary source represent the staff: patients and operating team, while either secondary sources are the contaminate air introduced from the VCCC system and the use of the infect instruments. About 10% of the hospital infections are determined by airborne bacteria and a variable fraction of these, not only in immunocompromised patients but also in healthy people, may cause the respirators pathologies. The aim of this paper was to estimate the microbial contamination, in 20 hospitals located in three regions of the South Italy, for a total 81 operating rooms. The results show that 17 of the 20 operating units and 45 out of 81 operating rooms examined are contaminated. Periodic inspections should be carried out in order to control and lower the biological risk for both the patients and the health care workers.
