Injuries to a patient’s nose (62.4) and mouth (62.1) are discussed elsewhere. Injuries to his larynx and trachea are rare and difficult. His main danger is the aspiration of blood into his lungs and surgical emphysema (65.10). Try to pass a cuffed tube beyond the wound, either through his nose or mouth, or through the wound itself. A tube will also reduce the danger of emphysema.
