About this study
For performing transnasal humidified rapid insufflation ventilatory exchange (THRIVE), jaw-thrust maneuver have to maintain to make sure the airway open and the CO2 clearance during apnoea. The objective of present study is to prove that nasopharyngeal airway facilitate THRIVE and no need jaw-thrust maneuver and maintain the similar PO2 and PCO2 during apnoea.
- Conditions
- Hypoxia, Hypercapnia

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Nasopharyngeal airwayDevice
THRIVE with a regular nasopharyngeal airway.
| Study group | Role | What they receive |
|---|---|---|
| THRIVE | No intervention | Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) during induction using jaw-thrust maneuver. |
| THRIVE with nasopharyngeal airway | Active comparator | Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) during induction with nasopharyngeal airway. Receives: Device: Nasopharyngeal airway |
What is being measured
The primary outcome is the main question the study is designed to answer.
The partial pressure of carbon dioxide (pCO2)
Measured: From start to end of THRIVE(20 minutes)
The partial pressure of oxygen(PO2)
Measured: From start to end of THRIVE(20 minutes)

Questions about this trial
What is this clinical trial studying?
A study testing Nasopharyngeal airway in people with Hypoxia and Hypercapnia, run by RenJi Hospital 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 4 inclusion and 14 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: status not confirmed, as of the sponsor's last update on 22 Jul 2019. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Diansan Su, Dr. (+862168383702, diansansu@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The partial pressure of carbon dioxide (pCO2) (time frame: From start to end of THRIVE(20 minutes)). The study lists 2 primary outcomes in all. 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 NCT03741998, 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 22 Jul 2019; AzTrials last refreshed its copy on 8 Nov 2026.
