[High-frequency jet ventilation in emergency tracheal puncture].

A case of obstruction of the upper respiratory tract is reported, in which an intubation or insufflation by rigid tracheobronchoscopes was not possible. Due to the anatomical situation after multiple operations and irradiation, coniotomy could not be performed. Blind puncture of the trachea with subsequent High Frequency Jet Ventilation has proved successful as an emergency approach to maintain respiratory function.
