Airway
Conditions
Brief summary
Patients presenting for elective surgery requiring tracheal intubation will be randomized to one of two different endotracheal tube (ETT) stylets. The intubation will be done with a GlideScope videolaryngoscope by a novice operator. The primary outcome is time to intubation.
Interventions
DEVICEGlideScope rigid stylet
Patients will be intubated either with a rigid stylet meant to be used with the GlideScope, or with a standard malleable stylet used with other modalities of intubation.

Inclusion criteria
* any adult patient scheduled for elective surgery. * ETT is indicated for the procedure in the opinion of the attending anesthesiologist. * any operator who has performed ≤ 10 GlideScope intubations.
Exclusion criteria
* any patient in whom the use of the GlideScope is contraindicated in the opinion of the attending anesthesiologist. * Patient with known cervical spine abnormalities. * any patients with known or probable difficult airways. (This rare occurrence is unlikely to be evenly distributed between the groups and could skew the data). * any patient requiring rapid sequence induction.
