Warning devices for prevention of dental injury during laryngoscopy. Preliminary report.
The prototypes of two novel warning devices for protection against dental trauma during direct laryngoscopy are described. Either can be attached to a standard laryngoscope blade (e.g., Macintosh). The basic design is that of a switch that is closed by pressure on the maxillary incisors by the laryngoscope blade.
