简要总结
In this study, patients undergoing painless gastroscopy were selected to change the nasal catheter oxygen delivery mode to oral oxygen delivery after endoscope implantation, in order to explore the effect of this oxygen delivery mode on the incidence of hypoxemia during general anesthesia gastroscopy.
详细描述
This study was a randomized controlled study in which patients undergoing elective painless gastroscopy were selected and grouped by random number table. The control group used conventional nasal cannula oxygen method: nasal cannula was used before, during and after gastroscopy was implanted and after withdrawing from the gastroscopy. Test group: Before the gastroscope enters the oral cavity, oxygen is administered through a nasal catheter via the nose. After the gastroscope enters the oral cavity, oxygen is administered through the nasal catheter via the mouth. After the gastroscope is withdrawn, oxygen is administered through the nasal catheter via the nose. The incidence of intraoperative hypoxemia was observed.
