A device for tracheal tube during CO2 laser irradiation in laryngomicrosurgery
1Department of Anesthesiology, Fujita Health University School of Medicine, Toyoake, Japan.
Abstract:
We devised that the segment of commercially available defensor II tube coming in contact with the vocal cord was concaved. We used this new tube during CO(2) laser irradiation in laryngomicrosurgery. We came to the conclusion that it was much more superior to the conventional tube in safety and resistance of the material to Co(2) laser irradiation and in increase of the operation field.
