In contrast, using conventional laryngoscopy, anesthesiologists have only a "keyhole" view of the airway structures; a view that may be further obscured during attempts to pass the ET. McGrath video laryngoscope is designed to provide a clear view of the vocal cords during intubation with little or no change in the laryngoscope technique, to simplify intubation of the difficult airway, and be less traumatic by minimizing the lifting force required during intubation6. The device consists of a laryngoscope handle that have been modified to provide a video image of airway structures on a screen, which can be conveniently located directly in front of the anesthesiologist. The device is extremely easy to learn how to use because most anesthesiologists are familiar with the use of the Macintosh blade. GlideScope is designed to optimize visualization by presenting to the operator an enlarged video image of airway structures. The GlideScope consists of a digital camera, called a video baton, which fits into a plastic laryngoscope blade and a light source on the side to provide a video image of airway structures on a screen, which can be conveniently located directly in front of the anesthesiologist. The GlideScope has been shown to provide superior views to traditional laryngoscopy and is potentially advantageous over direct laryngoscopy in difficult intubations.7 The GlideRite rigid stylet conforms to the GlideScope blade angulation, which, eliminates the need to manually shape the stylet to fit down the airway and improves maneuverability in endotracheal tube placement. The GlideRite rigid stylet works with the GlideScope system to reduce patient trauma. It is reusable and can be cleaned easily using an autoclave. It should be noted that several reports have been published describing trauma to the upper airway (anterior tonsillar pillar, soft palate) during intubation with video laryngoscopes.9-14 This risk underscores the importance of maintaining direct visual contact, as both blade and ET are initially inserted through the oral cavity until they are past the uvula. Recently, several reports using endoflex15-17 tube (which is similar to the endotrol tube) showed that there is considerable usefulness in normal direct laryngoscopy and video laryngoscopy (using glidescope) as well. The purpose of this study is to compare the safety and efficacy of Endotrol Tube (Covidien, Colorado, USA) compared to the conventional endotracheal tube in conjunction with the GlideRite stylet during videolaryngoscopy assisted endotracheal intubation.
