Trial summary

In this study, patients undergoing painless gastroscopy were selected to change the nasal catheter oxygen delivery mode to oral oxygen delivery after endoscope implantation, in order to explore the effect of this oxygen delivery mode on the incidence of hypoxemia during general anesthesia gastroscopy.

About this study

Official title: The Effect of Different Oxygen Delivery Methods of Nasal Catheter on the Incidence of Hypoxemia in Patients With High Risk of Hypoxia During Painless Gastroscopy

In this study, patients undergoing painless gastroscopy were selected to change the nasal catheter oxygen delivery mode to oral oxygen delivery after endoscope implantation, in order to explore the effect of this oxygen delivery mode on the incidence of hypoxemia during general anesthesia gastroscopy.

Read the detailed description

This study was a randomized controlled study in which patients undergoing elective painless gastroscopy were selected and grouped by random number table. The control group used conventional nasal cannula oxygen method: nasal cannula was used before, during and after gastroscopy was implanted and after withdrawing from the gastroscopy. Test group: Before the gastroscope enters the oral cavity, oxygen is administered through a nasal catheter via the nose. After the gastroscope enters the oral cavity, oxygen is administered through the nasal catheter via the mouth. After the gastroscope is withdrawn, oxygen is administered through the nasal catheter via the nose. The incidence of intraoperative hypoxemia was observed.

Questions about this trial

What is this clinical trial studying?

A study testing Oxygen delivery mode in people with Hypoxemia, run by Nanjing First Hospital, Nanjing Medical University 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 7 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 27 Jul 2026. 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?

Incidence of hypoxemia (time frame: Five minutes after finishing gastroscopy examination). 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 NCT06139081, 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 27 Jul 2026.
