[Qualitative characteristics of human exposure to air chemical pollutants in operating rooms].

UNLABELLED: For more than two decades many studies have been published searching for a link between exposure to volatile anaesthetic agents and health damage even if it is noteworthy that many other chemical substances can be found in the Operating Room. Purpose of this study was to demonstrate that the Operating Room is not a totally confined environment and that it is possible to perform an, at least qualitative, evaluation of many different polluting contaminants, even unexpected, to whom the working staff is exposed.

MATERIAL AND

METHODS

The study has been performed in the Operating Rooms of the Departments of Urology and Orthopaedics. Two methods have been employed: a long-casting sampling of volumes of air (with a sampling device composed of an enrichment system and a low flow aspirating pump) and an anaesthetic vapours and gas continuous analyzer. Results. We never recorded environmental levels of anesthetic higher than the currently accepted ones. Many other organic compounds of different kind have been found (irritants, cancer-organs). Their presence, not desirable in a place where a demanding work is performed, deserve further investigation and a quantitative evaluation of these compounds.
