Outline of Final Research Achievements

Dysfunction of the larynx, especially dysfunction as the airway and in protective reflex from aspiration, may cause sever ventilatory insufficiency. Therefore, it is clinically important to establish a method how to evaluate the laryngeal function at the tracheal extubation. We used cuff-leak pressure measurement as well as endoscopic findings from the larynx, anesthetic time, and type of surgical procedure, to judge whether the extubation was appropriate. However, our method was not supported statistically enough; the attempt of constructing decision tree resulted in failure even a low leak pressure was suggested to be indicative of successful tracheal extubation.
