[Anesthetic gases and neuropsychological tests]

The Authors observed, in a group of 15 subjects working in operating theatres and occupationally exposed to anesthetic gases, an increase of simple reaction average times and an increase of the latency of the wave V of the brainstem auditory evoked potentials. The small number of subjects doesn't allow to draw conclusions. Nevertheless the findings agree with first analogous studies. The Authors, therefore, think opportune to continue the research to acquire further evidence and to ascertain the validity of the current TLV.
