Vergleich der Arbeitsplatzbelastung während einer Xenon- oder Lachgasanästhesie

The aim of this study was to compare waste gas concentrations during xenon or nitrous oxide anaesthesia. A total of 64 patients were included in this study. Gas concentrations were measured with a mass spectrometer during anaesthesia. The probes were taken beside the patient's head and thorax and at a height of 180 cm above and at the floor level. In both groups, waste gas concentrations peak after intubation and extubation. Waste gas levels during xenon anaesthesia are low compared with nitrous oxide. The low waste gas levels of xenon seem to be beneficial for personnel at risk compared to nitrous oxide.
