Abstract

Background and objective: The aim of this study was to compare waste gas concentrations during xenon or nitrous oxide anaesthesia.

Methods: 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.

Results: In both groups, waste gas concentrations peak after intubation and extubation. Waste gas levels during xenon anaesthesia are low compared with nitrous oxide.

Conclusions: The low waste gas levels of xenon seem to be beneficial compared to nitrous oxide.
