Summary

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.

Detailed description

The oropharyngeal airway is an important airway auxiliary device for short-term airway management during the perianesthetic period, which can provide patients with an unobstructed airway during autonomous ventilation .The oropharyngeal vent has been proven to be successfully used in infants, the elderly and MRI, and can be used in short outpatient surgery instead of laryngeal mask .The oropharyngeal airway has a low incidence of pharyngeal trauma and laryngeal pain immediately after surgery, requiring a shorter exposure time of inhaled anesthetic and a lower concentration of propofol to successfully place it .During the operation to preserve spontaneous breathing, the oropharyngeal airway is introduced as a ventilation device .The new oropharyngeal airway can accept the implantation of gastroscopy and provide oxygen to patients without affecting the operation at the same time. In order to explore whether the new oropharyngeal airway can provide better oxygen to patients undergoing painless gastroenteroscopy and reduce the incidence of hypoxia during the operation, we have drafted this study and explored the safety of the new oropharyngeal airway in painless gastroenteroscopy.

Interventions

Type	Name	Description
DEVICE	New oropharyngeal airway	This product is produced and sold by Shanghai Elifu Medical Technology Co., LTD., and has been officially put into clinical use in March 2023.The product is named oropharyngeal airway for disposable endoscope, which is composed of nasal plug, bite, oropharyngeal channel, oxygen supply tube, lanyard and optional accessories carbon dioxide gas catheter and carbon dioxide collection tube.The model used in this study is JK (Oropharyngeal airway for endoscope with end-expiratory carbon dioxide Collection) with L/M/S three specifications, which is used to prevent airway obstruction caused by backward tongue fall during endoscopic surgery/examination, establish oropharyngeal airway for patients, and provide nasal oxygen at the same time
