Trial summary

Video intubating stylet can be safely and effectively used for nasotracheal intubation, but the optimal bending angle is still unknown. In this study, the optimal bending angle will be determined by comparing the intubation time and success rate of nasotracheal intubation with video intubating stylet at two different… Read more about this study

About this study

Video intubating stylet can be safely and effectively used for nasotracheal intubation, but the optimal bending angle is still unknown. In this study, the optimal bending angle will be determined by comparing the intubation time and success rate of nasotracheal intubation with video intubating stylet at two different bending angles.

Read the detailed description

intubation will be accomplished at 70 bending angle and 90 degrees bending angle in each group. intubation time, success rate, additional manoeuvres and epistaxis will be recorded and compared.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Questions about this trial

What is this clinical trial studying?

A study testing bending angle in people with Intubation;Difficult, run by Chinese Academy of Medical Sciences at 1 site in China.

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 1 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 15 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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 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?

Success rate of nasotracheal intubation (time frame: Procedure (From the beginning of intubation to the end of intubation)). 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 NCT04459481, which also lists 1 linked publication.

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 15 Jan 2021.
