Endotracheal Tube Shapes for Intubation With Videolaryngoscope

Not Applicable

Completed

• Conditions: Anesthesia

• Registration Number: NCT03524547
• Lead Sponsor: Eunah Cho, MD

Brief Summary

In this study, investigators will compare the efficacy of two shapes of endotracheal tube molded by stylet in endotracheal intubation using videolaryngoscope (McGrath MAC®). The participants will randomly be divided into two groups; J-shaped tube and 60-degrees-curved tube.

Detailed Description

Since the intubation using videolaryngoscope does not need straightened oral-pharyngeal-laryngeal axis, certain curvature of endotracheal tube is needed for the successful intubation using the videolaryngoscope.

Participants in both groups will be intubated with videolaryngoscope (McGrath MAC®). Stylet will be inserted in the endotracheal tubes and will be bent to a specific shape by the assigned group. In the J-shaped tube group, endotracheal tube will be molded to a shape similar to the blade of the videolaryngoscope (McGrath MAC®). In the 60-degrees-curved tube group, endotracheal tube will be bent 60 degrees. Time to intubation, intubation attempts and ease of intubation wil be assessed.
