Cervical Spine Motion During Tracheal Intubation: Video Laryngoscope vs Rigid Video Stylet

Not Applicable

Completed

• Conditions: Intubation
• Interventions: Device: rigid video stylet intubation; Device: video laryngoscope intubation

• Registration Number: NCT03120546
• Lead Sponsor: Seoul National University Hospital

Brief Summary

In this study, investigators are going to compare cervical spine motion during tracheal intubation using video laryngoscope or rigid video stylet in patients with simulated cervical immobilization.

Detailed Description

In patients with an unstable cervical spine, neck extension during tracheal intubation may result in harmful events such as spinal cord injury. Thus, it is important to minimize cervical spine motion in these patients. In this randomized crossover study, investigators are going to compare cervical spine motion during tracheal intubation using video laryngoscope or rigid video stylet in patients with simulated cervical immobilization.
