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.
背景与目的
本研究旨在比较氙气或氧化亚氮麻醉期间的废气浓度。
方法
本研究共纳入64例患者。麻醉期间用质谱仪测量气体浓度。探头置于患者头部和胸部旁边，以及高于地面180厘米处和地面水平。
结果
两组中，废气浓度在插管和拔管后达到峰值。与氧化亚氮相比，氙气麻醉期间的废气水平较低。
结论
与氧化亚氮相比，氙气较低的废气水平似乎有益。
