[Anaesthesia for diagnostic and therapeutic endoscopy procedures (author's transl)].

The experienced anaesthetist in endoscopic anaesthesia in otolaryngology appreciates the need for adequate alveolar ventilation and that the risks are considerable. Certain principles, which have been found useful are presented. From five anaesthetic techniques for laryngeal microsurgery the injector method is described in detail. This method has proved very advantageous especially for surgical procedures on the posterior laryngeal commissure and for the treatment in special instances of tracheal stenosis. The technique mentioned were used without serious complications in about 1000 endoscopies in the last five years.
