[The problems of intubation lesions with long-term artificial respiration (author's transl)].

Necroses of the tracheal wall with esophagotracheal and mediastinal fistulas are a serious complication of modern long-term artificial respiration through inflatable tubes. Different types of cuff, a number of control and monitoring mechanisms against over-pressure in the cuff are described. The intermittent blocking and unblocking method seems to be of importance. A simple and reliable method of intermittent occlusion of the trachea is obtained with the new Abouav and Finley parachute cuff with pressures which never exceed the artificial respiratory pressure of the ventilation system.
