Abstract

STUDY DESIGN:

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

DESIGN:

Prospective, randomized study.

SETTING:

Laboratory in vitro testing of endotracheal tubes.

INTERVENTIONS:

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.

MEASUREMENTS:

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

MAIN RESULTS AND CONCLUSION:

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.
