Summary

Patients presenting for elective surgery requiring tracheal intubation will be randomized to one of two different ETT stylets. The primary outcome is time to intubation.

The null hypothesis is that there will be no difference.

The GlideScope video laryngoscope (Verathon) is a widely used intubating device that uses a high-resolution camera embedded into a plastic laryngoscope blade. An LED provides illumination. The GlideScope often provides a good laryngoscopic view, but passing the endotracheal tube (ETT) through the vocal cords is sometimes difficult. Because of the 60 degree anterior curvature of the GlideScope's blade, ETT's must have stylets inserted so that the ETT distal tip can be positioned anteriorly. Various authors have recommended different angles of the ETT to optimally place it into the trachea, including matching the GlideScope's 60 degree angle, or configuring the ETT with a 90 degree bend. Previous studies demonstrated that 90 degree sharp bend was both faster and subjectively easier in a heterogeneous group of intubators. With the introduction of the Flex-It stylet by Parker Medical, the question arises as to the the best configuration of stylet for the ETT. Therefore, this prospective, randomized, single-blinded trial is proposed.
