Effect of xenon on endotracheal tube cuff.
METHODS
To investigate the effect of xenon on the endotracheal tube cuff in comparison to that of nitrous oxide.


METHODS
Prospective, randomized study.


METHODS
Laboratory in vitro testing of endotracheal tubes.


METHODS
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.


METHODS
The intra-cuff pressure and gas volume in the cuff were measured for 3 hours.


CONCLUSIONS
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.
