[Injector ventilation in direct laryngoscopy].

A newly-developed apparatus system for injector-ventilation is described, which consists of the main parts of the modified respirator and the injector-tube. After laboratory and clinical tests this system regularly finds application in direct laryngoscopy--diagnosis and microsurgery--of laryngeal diseases. In the technique described the jet-pump-effect is made use of, contrary to the jet-ventilation which is based on the principle of the free jet. Depending on the tasks to be solved the standard laryngoscopes by Kleinsasser as well as those by Brandt can be used. According to our experiences, that have so far been obtained in more than 250 patients, the method of the injector-ventilation guarantees sufficient ventilation.
