Study of a New Oropharyngeal Airway to Reduce Low Oxygen Levels During Painless Gastroenteroscopy in Adults 18 to 95

What this Trial Is About

Researchers are evaluating a new oropharyngeal airway device designed to improve airway management during painless gastroenteroscopy. The study aims to determine if this device can reduce airway obstruction and hypoxia incidents, especially in obese and elderly patients who are more vulnerable to oxygen drops during anesthesia. This randomized, double-blind trial investigates the safety and effectiveness of this new airway compared to traditional nasal oxygen delivery methods. Participants are divided into two groups. Both groups receive oxygen at 5-6 liters per minute for about one minute before anesthesia induction, with sedatives propofol and sufentanil administered. The experimental group uses the new oropharyngeal airway connected to the endoscopic bite to deliver oxygen and monitor carbon dioxide levels, while the control group uses a nasal catheter. Propofol is continuously infused to maintain anesthesia until the procedure ends. Throughout the procedure, researchers observe the incidence of hypoxia and severe hypoxia, coughing, laryngeal spasm, and other adverse events. They also record drug dosages and endoscopist satisfaction. Monitoring includes oxygen saturation and carbon dioxide levels. The total participation includes anesthesia, endoscopy, and 30 minutes post-procedure for satisfaction assessment. The study will provide clinical experience and reference for anesthesia care in obese patients undergoing painless gastroenteroscopy.
