[Intubation aid by a rigid endoscope]

A method has been developed making it possible to look around intubation obstacles with the aid of rigid angular-lens systems. A glottis that is not or is only partly visible in direct laryngoscopy can be visualized endoscopically. The normal intubation technique is retained. A rigid endoscope is additionally introduced into the oropharynx, the glottis located endoscopically, and the endoscope secured to the laryngoscope in the position. The free hand can then be used to advance the tube through the glottis into the trachea under endoscopic control. This endoscopic method is intended to augment the physician's instrumental repertoire.
