[GlideScope Ranger: clinical assessment of the performance in 100 patients].

To evaluate the suitability of GlideScope Ranger, endotracheal intubation was performed in 100 surgical patients undergoing general anesthesia. The time to complete intubation, percentage of glottic opening score and optimizing procedures were recorded. GlideScope Ranger allowed visualization of the glottis and successful intubation in all 100 patients, including two patients with difficult airway. Endotracheal intubation was performed within one minute in 81 cases, and percentage of glottic opening score of 75% or more was obtained in 75 cases. It was easily handled not only by experienced anesthetists but also by novice personnel. GlideScope Ranger could be an effective aid to airway management in surgical patients.
