[Evaluation of several neuropsychological parameters in subjects occupationally exposed to anesthetics].

51 workers, occupationally exposed to anaesthetic gases and vapours (nitrous oxide, halothane, and isoflurane), were studied monitoring their environmental and biological exposure. Moreover, they were tested for visual reaction times and neurobehavioural batteries. There was no evidence of important neurotoxic effects nor of neurobehavioural problems with low concentrations of anaesthetics.
