A Comparison of Cervical Spine Movement During Tracheal Intubation Using the Pentax or the Glidescope

An interventional study of The glidescope video laryngoscopy and The Pentax airwayscope in C-spine Movement During Intubation, sponsored by Prince of Songkla University. Status unknown at 1 site in Thailand. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2011-05-04.

Study summary

Both Glide scope and Pentax laryngoscope are video laryngoscope that provide the better view with minimal cervical spine movement. This study wants to compare cervical spine movement during intubation when using these two devices. The C-spine motion will be recorded by using fluoroscopic video to measure the angular displacement of the vertebrae.

Read the detailed description

The primary outcome is the angular displacement of the vertebrae and secondary outcome is the hemodynamic changes after intubation.

The record gives a start of May 2010, a primary completion of Jun 2011 and a completion of Jun 2011. It does not say whether these dates are actual or estimated.

What these dates mean

Start.: When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.: When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.: When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.: Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.

No changes since tracking began. The registry record was last updated on May 4, 2011, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
