Core Tip

Core Tip: This study is a prospective, randomized controlled trial aimed to compare the efficacy and safety of Wei nasal jet tube (WNJT) and nasal prongs for supplemental oxygen during gastroscopy with propofol monosedation in obese patients when a moderate oxygen flow is used. Our results show that the WNJT compared with the nasal prongs for supplemental oxygen is more effective for prevention of hypoxemia during gastroscopy with propofol mono-sedation, though it may result in a potential risk of epistaxis in few patients.
