Abstract

Ignition or combustion of endotracheal tube during CO₂ laser laryngomicrosurgery may cause fatal lung disorders. We had one experiment on ignition and combustion of endotracheal tubes by CO₂ laser beam. And We obtained several conclusions as follows.
(a) Silicon endotracheal tube was non-flammable.
(b) Spiral endo-tracheal tube was also non-flammable.
(c) Pulse wave was recommended and three second interval was necessary.
(d) Four sheets of moist gauze were necessary to prevent cuff-trouble.
(e) It was desired to set O₂ concentration below 25% in the use of silicon endotracheal tube.
