Summary
Brief summary (as posted)
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.
