Effect of Modified Stylet Angulation on the Intubation With GlideScope®

Stylet Angulation of Seventy Degrees Reduced Time to Intubation With the GlideScope®: A Prospective Randomized Trial

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.

Inclusion Criteria:

• Patients requiring endotracheal intubation for general anesthesia

Exclusion Criteria:

• Difficult airway
• Rapid sequence induction
• Recent sore throat
• Fragile teeth
• Contraindication for videolaryngoscope
• Head and neck surgery
