Trial summary

This study aims to compare the effect of the use of supraglottic jet oxygenation and ventilation (SJOV) with high-flow nasal oxygen therapy (HFNO) on reducing the rate of hypoxia during gastrointestinal endoscopic procedures in deeply sedated patients at high altitudes. Read more about this study

About this study

Official title: Hypoxemia During Deep Sedation for Gastrointestinal Endoscopy at High Altitudes: High-flow Nasal Oxygen Therapy vs. Supraglottic Jet Oxygenation and Ventilation

This study aims to compare the effect of the use of supraglottic jet oxygenation and ventilation (SJOV) with high-flow nasal oxygen therapy (HFNO) on reducing the rate of hypoxia during gastrointestinal endoscopic procedures in deeply sedated patients at high altitudes.

Read the detailed description

The participants will be randomly allocated to either SJOV or HFNO in a 1:1 ratio using block randomization with variable block sizes of four or six randomized. In the HFNO group, oxygen supplementation is delivered at 35 liters min-1 with a fraction of inspired oxygen (FiO2) of 100%. In the SJOV group, SJOV is conducted using a Wei nasal jet tube (WNJ, Well Lead Medical Co. Ltd, Guangzhou, China) which is connected to a manual jet ventilator (Well Lead Medical Co. Ltd, Guangzhou, China) via its jet port. The initial settings of SJOV were as follows: driving pressure (DP) 15 psi; respiratory rate (RR) 20 bpm; inspiratory-to-expiratory (I/E) ratio 1:2, and gas supply, 100% oxygen.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Hypoxia during sedation

    An SPO2 of 75 - 89% for < 60 s

    Measured: During sedation procedure

Secondary outcomes (3)
  1. respiratory-related complications

    pulmonary aspiration, respiratory depression (SPO2 = 90-95%) and severe hypoxia (SPO2 < 75% or < 90% for > 60s)

    Measured: During sedation procedure

  2. cardiovascular-related complications

    hypotension (systolic blood pressure < 90 mmHg), hypertension (systolic blood pressure > 160 mmHg), bradycardia (heart rate < 50 beats/min), tachycardia (heart rate > 120 beats/min)

    Measured: During sedation procedure

  3. fatal complications

    severe anaphylactic reactions, myocardial infarction, cardiac arrest and death

    Measured: from sedation initiation to 20 min after patients are awake

Questions about this trial

What is this clinical trial studying?

A study testing SJOV and HFNO in people with Hypoxia and High Altitude, run by Peking University People's 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 3 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: status not confirmed, as of the sponsor's last update on 17 Oct 2022. 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 Bailin Jiang (86-13810986114, jiangbailin@bjmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Hypoxia during sedation (time frame: During sedation procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Oct 2022.
