About this study
Official title: Supraglottic Jet Oxygenation and Ventilation (SJOV) for Hypoxemia During Deep Sedation for Gastrointestinal Endoscopy at High-altitude
This study aims to determine whether the use of SOJV could reduce the rate of hypoxia during gastrointestinal endoscopic procedures in deeply sedated patients sedated at high altitude comparing to the supplemental oxygen administration via nasal cannula.
Read the detailed description
The participants will be randomly allocated to either SJOV or nasal cannula oxygen supply in a 1:1 ratio using block randomization with variable block sizes of four or six randomized. In the nasal cannula oxygen supply group, oxygen supplementation at 2 liters min-1 is delivered via a nasal cannula. 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.
- Conditions
- Hypoxia, High Altitude
- Being tested
- Supraglottic jet oxygenation and ventilation, Nasal cannula oxygen supply
- Medical subject headings
- Hypoxia, Altitude Sickness
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Supraglottic jet oxygenation and ventilationProcedure or surgery
Supraglottic jet oxygenation and ventilation 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 are: driving pressure (DP) 15psi, respiratory rate (RR) 20 bpm, inspiratory-to-expiratory (I/E) ratio 1:2, and gas supply 100% oxygen.
Nasal cannula oxygen supplyProcedure or surgery
Oxygen supplementation at 2 liters min-1 is delivered via a nasal cannula
| Study group | Role | What they receive |
|---|---|---|
| Supraglottic jet oxygenation and ventilation | Experimental | Supraglottic jet oxygenation and ventilation is conducted for the participants during sedation. Receives: Procedure: Supraglottic jet oxygenation and ventilation |
| nasal cannula oxygen supply | Placebo comparator | Oxygen supplementation is delivered via a nasal cannula to the participants during sedation. Receives: Procedure: Nasal cannula oxygen supply |
What is being measured
The primary outcome is the main question the study is designed to answer.
Hypoxia during sedation
An SPO2 of 75 - 89% for < 60 s
Measured: During sedation procedure
Secondary outcomes (3)
respiratory-related complications
pulmonary aspiration, respiratory depression (SPO2 = 90-95%) and severe hypoxia (SPO2 < 75% or < 90% for > 60s)
Measured: During sedation procedure
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
fatal complications
severe anaphylactic reactions, myocardial infarction, cardiac arrest and death
Measured: from sedation initiation to 20 min after patients are awake

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05304923, 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?
