[Use of ultrasonic-aerosol for surface analgesia of the respiratory tract. First experiences with a new technique of endotracheal intubation under local anesthesia (author's transl)].

On 10 patients and 5 probands we used topical ultrasonic aerosol inhalation anaesthesia for endotracheal intubation during spontaneously breathing and local anaesthesia. 6 ml lignocaine 10% was inhaled for 4 minutes. There were no complications during or after inhalation. We injected a hypnotic just before intubation in most cases.
