Abstract
The aim of this study was to assess whether a sample of 37 anaesthetists occupationally exposed only to N2O showed any deterioration in vigilance and/or mood. The anaesthetists were examined with three neurobehavioural tests (Simple Reaction Time and Colour Word Vigilance to measure the vigilance and Mood Rating Scale to evaluate the level of stress and arousal) and underwent N2O biological monitoring (to correlate the test results with the N2O exposure) on the first and on the last day of the work week, before and after work in the operating room. No significant relationship was found between the biological monitoring and the test results. The only significant statistical difference was found between the beginning and the end of each workday in the arousal level, regardless of the result of the biological monitoring.Cilj je ovoga ispitivanja bio utvrditi do kakvih promjena budnosti i raspoloženja dolazi u 37 anesteziologa profesionalno izloženih didušikovu oksidu. Promjene u budnosti ispitane su s pomoću zadatka jednostavnog vremena reagiranja i zadatka pozornosti, a promjene u raspoloženju s pomoću skale procjene različitih raspoloženja. Mjerenja su izvršena na početku i na kraju prvog i zadnjeg radnog dana u tjednu, a mjerenja didušikova oksida u urinu izvršena su samo na kraju radnog vremena prvoga i posljednjeg radnog dana u tjednu. Nije utvrđena povezanost između rezultata biološkog monitoringa i psihologijskog ispitivanja. Konzistentne statistički značajne razlike utvrđene su jedino u subjektivnim procjenama budnosti na početku i na kraju radnog dana
