[Experimental study on compatibility of endotracheal prostheses (author's transl)].

On 34 rabbits we supported the trachea with endotracheal tubes of PVC or PTFE (Teflon). Results are discussed. To obtain satisfying results, it is necessary to use short, soft and inert tubes without sharp edges at the ends. The prostheses should be fixed in the trachea. Immobilisation of head and neck with a plaster-collar minimizes mechanical irritation.
