Clinical 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.


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.

HFNO
HFNO is conducted. Oxygen supplementation is delivered at 35 liters min-1 with a fraction of inspired oxygen (FiO2) of 100%.

Outcome

Type Measure Description Time frame Safety issue
Primary Hypoxia during sedation An SPO2 of 75 - 89% for < 60 s During sedation procedure
Secondary respiratory-related complications pulmonary aspiration, respiratory depression (SPO2 = 90-95%) and severe hypoxia (SPO2 < 75% or < 90% for > 60s) During sedation procedure
Secondary 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) During sedation procedure
Secondary fatal complications severe anaphylactic reactions, myocardial infarction, cardiac arrest and death from sedation initiation to 20 min after patients are awake
