Operating-room airway fires are serious and potentially fatal complications. To prevent airway fire in CO 2 laser surgery of the larynx, many techniques and devices have been developed. Using laser safe tube is one of the common methods of preventing airway fire, but it is very expansive and hard to treat. In this study, we used a fire-resistant tape to protect the endotracheal tube and had very successful results in experiments with CO 2 laser. In this article, we introduce the technique of using a fire-resistant tape to protect endotracheal tube.
