[Suffocation, an important lethal factor for otorhinolaryngological disease].

OBJECTIVE: To study the importance of supervision in respiratory tract for otorhinolaryngological disease. METHOD: Nine cases died of suffocation were reported and the causes were analyzed. In the 9 cases there were 3 cases with the foreign body in bronchus, 2 cases with the trachea bleeding, 2 cases with laryngopharyngeal tumor and 2 cases with bleeding from nasopharyngeal carcinoma. RESULT: All cases were died of suffocation. CONCLUSION: Suffocation is an important lethal factor for many otorhinolaryngological disease. Tracheotomy is a prompt and effective management for the suffocation resulting from upper respiratory tract obstruction. Tracheoscopy is the first choice for patients with lower respiratory tract obstruction. And the continuous inflating pressure with intubation in cases with trachea bleeding should be avoided.
