NCT04500392

Brief Summary

Hypoxia is the most common adverse event during gastrointestinal endoscopes sedated with propofol and sufentanil, especially in obese people. In the present study, high-flow nasal cannula oxygenation will be utilized in order to reduce the incidence of hypoxia among obesity.

Outcome Measures

Primary Outcomes (1)

  • The incidence of hypoxia

    (75% ≤ SpO2 \< 90% for \<60 s)

    Patients will be followed for the duration of hospital stay, an expected average of 2 hours]

Secondary Outcomes (3)

  • The incidence of subclinical respiratory depression

    Patients will be followed for the duration of hospital stay, an expected average of 2 hours

  • The incidence of severe hypoxia

    Patients will be followed for the duration of hospital stay, an expected average of 2 hours

  • Other adverse events include other adverse events recorded by tools proposed by the World Society of Intravenous Anesthesia International Sedation Task Force and HFNC supportive oxygen therapy-related adverse events.

    Patients will be followed for the duration of hospital stay, an expected average of 2 hours
