Randomized Controlled Trial
The Shikani optical stylet as an alternative to the GlideScope® videolaryngoscope in simulated difficult intubations--a randomised controlled trial.
The GlideScope(®) videolaryngoscope is widely utilised in the management of the difficult airway. However, complications such as mucosal injury, palatal and tonsillar perforations have been reported with its use. The Shikani optical stylet has shown promise in aiding difficult intubations. ⋯ The mean (SD) time to intubation was 64 (37) s when using the GlideScope and 58 (26) s in the Shikani group (p = 0.48). A higher incidence of airway mucosal injury was noted in patients intubated with the GlideScope videolaryngoscope, compared with the Shikani optical stylet (5 vs 0, respectively, p = 0.05). This trial suggests that the Shikani optical stylet is a viable alternative to the GlideScope videolaryngoscope in the management of the difficult airway.

Randomized Controlled Trial Comparative Study
Comparison of the GlideScope® videolaryngoscope and the Macintosh laryngoscope for double-lumen tube intubation.
Intubation with a double-lumen tube is important for achieving one-lung ventilation and facilitating thoracic surgery. The GlideScope(®) videolaryngoscope (Verathon Inc., Bothell, WA, USA) is designed to assist tracheal intubation for patients with a difficult airway. We wished to compare the GlideScope and direct laryngoscopy for double-lumen tube intubation. ⋯ There was no difference in the success of the first attempt at intubation (26/30 (87%) and 30/30 (100%) for Macintosh and GlideScope groups, respectively; p = 0.112). The incidence of sore throat and hoarseness was higher in the Macintosh group (18 (60%) and 14 (47%), respectively) than in the GlideScope group (6 (20%) and 4 (13%), respectively; p = 0.003 and 0.004). We conclude that double-lumen tube intubation in patients with predicted normal laryngoscopy is easier using the GlideScope videolaryngoscope than the Macintosh laryngoscope.

Comparative StudyA comparison of an integrated suction blade versus a traditional videolaryngoscope blade in the endotracheal intubation of a hemorrhagic cadaver model - a pilot study.
In this pilot study, we evaluated two types of videolaryngoscope blades (integrated suction vs. traditional) with the Storz CMAC videolaryngoscope in the intubation of a lightly embalmed hemorrhagic cadaver model. No significant differences were found between the devices in the success rates for the intubations. The study subjects indicated a preference for the integrated suction blade in hemorrhagic airway intubation.

User preference comparing a conventional videolaryngoscope blade vs. a novel suction videolaryngoscope blade in simulated hemorrhagic airway intubation.
The hemorrhagic airway makes visualization during laryngoscopy and intubation difficult. A specially designed videolaryngoscope blade with integrated suction was developed and studied in a simulated hemorrhagic airway at the Omaha VA Medical Center. Results show that, if available, many users would choose to include this new suction device in their standard airway carts due to its "always there" design.
