简要总结
The GlideScope® videolaryngoscope usually visualize glottis better than the conventional laryngoscope. Under the visualization of glottis by GlideScope®, the insertion of endotracheal tube, however, is challenging.
The goal of this study was to determine which of two stylet (70° vs 90°) was better, as determined by time to intubation.

研究组 & 干预措施
90 degree
The ETT with the 90° angle stylet was bent at a point 8 cm from its distal end.
干预措施: Glidescope guided intubation (Procedure)
90 degree
The ETT with the 90° angle stylet was bent at a point 8 cm from its distal end.
干预措施: GlideScope® (Device)
70 degree
The ETT was bent by 70° at a point 6 cm from its distal end and the proximal portion of the ETT was formed as the shape of the GL blade until the point of the handle.
