Intratracheal Intubation in Critical CareMACMANNCT02413723
McGrath Mac Videolaryngoscope Versus Macintosh Laryngoscope for Orotracheal Intubation in Critical Care Unit
A study testing Videolaryngoscope and Standard laryngoscope in people with Intratracheal Intubation in Critical Care, run by Centre Hospitalier Departemental Vendee at 7 sites in France.
Trial summary
The aim of this study is to demonstrate that the rate of successful orotracheal intubation at first laryngoscopy will be higher in patients intubated with McGrath Mac videolaryngoscope compared to patients intubated with classical Macintosh laryngoscope in patients requiring an orotracheal intubation in ICU.

| Study group | Role | What they receive |
|---|---|---|
| Videolaryngoscope McGrath Mac | Active comparator | McGrath Mac videolaryngoscope will be used for laryngoscopy for patient's intubation Receives: Device: Videolaryngoscope |

What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of successful orotracheal intubation at first laryngoscopy
Number of successful intubation at first laryngoscopy in one arm/number of included patients in the same arm.
Measured: intubation procedure, an expected average of 15 minutes
Secondary outcomes (2)
Proportion of successful orotracheal intubation all laryngoscopies pooled
Measured: intubation procedure, an expected average of 15 minutes
Time to successful orotracheal intubation
Defined by the time between the beginning of induction (injection of anesthetic drugs) and the time of confirmation of the intratracheal nature of the endotracheal tube (defined as apparition of first inflexion on the expired carbon dioxide curve)
Measured: intubation procedure, an expected average of 15 minutes

Questions about this trial
What is this clinical trial studying?
A study testing Videolaryngoscope and Standard laryngoscope in people with Intratracheal Intubation in Critical Care, run by Centre Hospitalier Departemental Vendee at 7 sites in France.
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 9 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: finished, as of the sponsor's last update on 17 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in France. 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. Some participants in this study may receive a placebo. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Proportion of successful orotracheal intubation at first laryngoscopy (time frame: intubation procedure, an expected average of 15 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02413723, which also lists 3 linked publications.
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 17 Nov 2025; AzTrials last refreshed its copy on 8 Nov 2026.
