To investigate the effect of xenon on the endotracheal tube cuff in comparison to that of nitrous oxide.
Prospective, randomized study.
Laboratory in vitro testing of endotracheal tubes.
Exposure of air-filled endotracheal tube cuffs to xenon or nitrous oxide (79 vol%) mixed with a balance of oxygen (21 vol%) for 3 hours.
The intra-cuff pressure and gas volume in the cuff were measured for 3 hours.
Increase in pressure and gas volume was significantly less and slower with xenon than with nitrous oxide. More nitrous oxide passes into the cuff than xenon.
为了研究氙气与一氧化二氮相比对气管导管套囊的影响。
前瞻性随机研究。
气管导管的实验室体外测试。
将充有空气的气管导管套囊暴露于与氧气（21%体积）混合的氙气或一氧化二氮（79%体积）中3小时。
在3小时内测量套囊内压力和套囊内气体体积。
与一氧化二氮相比，氙气导致的压力和气体体积增加显著更小且更慢。进入套囊的一氧化二氮比氙气更多。
