[Supraglottic jet ventilation during direct laryngoscopy]

During 1983-1987 at the ENT Clinic, Faculty of General Medicine, Charles University, Prague 779 direct laryngoscopic examinations made where the technique of supraglottic ventilation was used. The method was introduced for the sake of greater safety during laser surgery of the larynx in the first 57 patients analysis of the blood gases in capillary blood was performed and the results were satisfactory. The technique which is described in detail is considered equally reliable and safe as ventilation by classical intubation. It provides, however, a better overall orientation of the larynx, better use of the laser technique, it saves operation time and intubation material.
