Nasal Mask Kit in Gastrointestinal Endoscopy

Not Applicable

Recruiting

• Conditions: Gastric Polyp; Colon Polyp; Hypoxia; Gastric Cancer; Colon Cancer; Esophageal Cancer
• Interventions: Device: nasal mask oxygen kit; Device: regular nasal cannula

• Registration Number: NCT05405530
• Lead Sponsor: RenJi Hospital

Brief Summary

Hypoxia is the most common adverse event in gastrointestinal endoscopes sedated with propofol. The nasal mask oxygen kit has good sealing to ensure an adequate oxygen supply and is convenient and economical.The aim of this randomized study was to determine whether the nasal mask oxygen kit reduces the incidence of hypoxia in gastrointestinal endoscopes procedures.
