简要总结
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.
