is a novel device designed for endotracheal intubation. It contains a small camera and a light source at the tip of the blade and therefore offers the user an image of the vocal cords and the surrounding airway anatomy on an LCD screen attached to the laryngoscope handle. The positioning of the McGrath^®^blade tip is the same as a Macintosh blade. Once the glottis is visible on the monitor, an endotracheal tube is advanced through the vocal cords.

The GlideScope^®^Ranger (Verathon Inc., Bothell, WA, USA) is a video laryngoscope with a separate monitor connected to the handle via a cable. The tip of the blade is equipped with a miniature camera and an LED light.

Several publications have shown a benefit with both instruments in expected and unexpectedly difficult airwaysMcGrath^®^devices compared to the first attempt. However, after the third trial, no further decrease in time to the first ventilation was observed. This confirms a rapid learning curve for the GlideScope^®^and McGrath^®^devices and is comparable to earlier studies \[[@B19]-[@B21]\]. In another publication, the learning curve for both video laryngoscopes in an airway simulator with a normal airway was studied. Sixty anaesthetists participated in the study. After five attempts, the time differences to successful endotracheal intubation persisted when compared with the Macintosh blade \[[@B21]\].

The time until glottic view in the second of the six \"normal airway\" attempts was nearly equal for all devices. However, the overall times to first ventilation for the McGrath^®^and the GlideScope^®^devices were longer when compared to the Macintosh laryngoscope. This was especially true for the
