GlideScope Groove Versus Macintosh Blade for Double-Lumen Endotracheal Tube Intubation
A study testing GlideScope Groove in people with Intubation, Intratracheal, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 2 sites in Canada.
Trial summary
A new GlideScope videolaryngoscope has been developed, which utilizes a track on the superior surface of the blade to guide the endotracheal tube, which is advanced in the track as opposed to "free-hand" along the inferior surface, where the camera is located. Read more about this study

About this study
Official title: Comparison of GlideScope Groove to Macintosh Blade for Orotracheal Intubation With Double-Lumen Endotracheal Tube: a Randomised Controlled Trial
A new GlideScope videolaryngoscope has been developed, which utilizes a track on the superior surface of the blade to guide the endotracheal tube, which is advanced in the track as opposed to "free-hand" along the inferior surface, where the camera is located. This new GlideScope can be used for double-lumen endotracheal tubes (DLT). The investigators hypothesize that this GlideScope will be easier to use than the Macintosh blade.

- Intubation, Intratracheal

Questions about this trial
What is this clinical trial studying?
A study testing GlideScope Groove in people with Intubation, Intratracheal, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 2 sites in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 28 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Duration of Intubation (time frame: Day 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Feb 2019.
