Effect of New Oropharyngeal Airway on Incidence of Hypoxia During Painless Gastroenteroscopy in Elderly Patients

With the aging of Chinese population, the early screening of gastrointestinal diseases and the promotion and implementation of comfortable medical treatment, more and more elderly patients choose painless gastroenteroscopy for diagnosis and treatment.However, the incidence of anesthesia-related adverse reactions and complications is high in elderly patients.Hypoxemia caused by anesthetic-induced respiratory depression and airway obstruction is a serious complication in painless gastroenteroscopy.Severe hypoxemia not only requires emergency airway intervention, such as mask ventilation or even tracheal intubation, but also leads to the interruption of endoscopic diagnosis and treatment.Advanced age was an independent risk factor for hypoxemia during painless gastroenteroscopy,This study observed the effect of a new type of oropharyngeal ventilation in improving the elderly painless gastroenteroscopy anesthesia hypoxemia and reducing intraoperative airway intervention, so as to evaluate the safety and effectiveness of a new type of nasopharyngeal ventilation in the elderly painless gastrointestinal diagnosis and treatment, and provide clinical reference.
