[Cooperation between the occupational health department and the technical assistance office to confront the problem of pollution by anesthetics].

In the past years the problem related to occupational exposure to anaesthetic gases in operating rooms has been dealt with in different ways by each hospital administration, and frequently with little cooperation between the health departments involved. At the Spedali Civili of Brescia in the five year period, 1987-1991, a monitoring activity of nitrous oxide (N2O) and halogenated anaesthetics was performed in 30 operating rooms. This lead to a noticeable reduction of environmental concentrations of these substances. Favourable results have been achieved principally by maintenance and/or substitution of anesthesiological machine parts. In order to organize and facilitate this program a close collaboration was accomplished between the Medical Direction of the Hospital and the Occupational Health Department, with the support of the Technical Assistance Department.
