Summary

Obesity is associated with adverse airway events including desaturation during deep sedation. Previous studies have suggested that high-flow nasal oxygenation may be superior to regular (low-flow) nasal cannula for prevention of hypoxia during Sedated Gastrointestinal Endoscopy in non-obesity patients. The prerequisite of high-flow nasal oxygenation is keeping airway patency. Our pervious study demonstrated that nasopharyngeal airway has the similar efficacy of jaw-lift. In present study we aimed to determine whether high-flow nasal oxygenation combined with nasopharyngeal airway could reduce the incidence of hypoxia during Sedated Gastrointestinal Endoscopy in obese patients.

Conditions

Interventions

DEVICE

High-flow nasal oxygenation combined with nasopharyngeal airway

The patients receive an oxygen flow of 30 L/min for preoxygenation with a high-flow oxygenation device before losing of conscious. At the time of the abolition of the eyelash reflex, the gas flow was increased to 60 L/min with an inspired oxygen fraction 100% and the nasopharyngeal airway was placed.

DEVICE

Regular nasal cannula combined with nasopharyngeal airway

The patients receive an oxygen flow of 6 L/min for preoxygenation with a regular nasal cannula until the end of procedure. At the time of abolition of the eyelash reflex, the nasopharyngeal airway was placed.
