Study Objective: The objective of this study was to demonstrate that Google Glass (GG) offered an effective video-assisted teaching method for endotracheal intubations by direct laryngoscopy compared to traditional methods. Method(s): One hundred two medical students at the University of Toledo College of Medicine were divided into two groups: a GG group and a control group. Each group was given an instruction tutorial: one via the traditional method and one using the GG, video-assisted method. Each student was given 3 attempts to successfully intubate a mannequin and their times were recorded and graded based on success. Failed intubations, indicated by entry into the esophagus, were also recorded. MANOVA and Chi Square tests were performed to assess the statistical significance of the findings. Result(s): The mean performance time means for the GGserial attempts were 20.95+/- 13.36 seconds, 15.48 +/- 10.48 seconds, and 13.66 +/- 7.74 seconds, respectively. For the traditional method serial attempts, the mean performance times were 29.15 +/- 19.65 seconds, 20.54 +/- 14.28 seconds, and 17.05+/- 11.01 seconds, respectively. Although the GG group intubated faster than the control group, a MANOVA analysis showed a difference between both groups that did not reach significance (P = .077). In addition, a Chi Square test did not show a significant difference between groups (P = .08) when assessing successful esophageal intubations between the two methods. Conclusion(s): GG provided equivalent results compared to the traditional teaching method for endotracheal intubation by direct laryngoscopy. Therefore this technique should be strongly considered in educational forums since it would serve as a more efficient teaching method allowing larger audiences to view the procedure from a firsthand perspective, while maintaining an adequate proficiency in demonstrating the procedure.
