About this study

Official title: Effect of High-flow Nasal Oxygenation on Safe Apnea Time in Children With Open Mouth

This is a prospective randomized controlled trial comparing high flow nasal cannula and buccal oxygenation as method of oxygenation during apnea in children.

Read the detailed description

This is a prospective randomized controlled trial comparing two oxygenation methods for prolongation of apnea time in children aged 0 to 10 years old.

This study measures time for the pulse oximetry drop from 100% to 92% after oxygenation with 100% oxygen, applying high flow nasal cannula or buccal oxygen insufflation via an oral Ring-Adair-Elwyn endotracheal tube connected to oxygen.

What is this clinical trial studying?

A study testing High flow nasal cannula and Buccal oxygenation in people with Anesthesia, General and Apnea, run by Seoul National University Hospital at 1 site in South Korea.

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 6 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 28 Jul 2023. 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 South Korea. 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?

Apnea success rate (time frame: From start of apnea to drop of pulse oximetry to 92%, up to 520 seconds). 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 NCT04849520, which also lists 14 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 28 Jul 2023.
