Summary

The objective of this study was to investigate the application of new oropharyngeal airway management in patients undergoing painless gastroenteroscopy.To see if it can really solve the problem of airway obstruction during anesthesia.The incidence of hypoxia (Spo2\<90%, t\>10s) and severe hypoxia (Spo2\<85%) during anesthesia and sedation, as well as the incidence of cough and laryngeal spasm, as well as the dose, endoscopist satisfaction, and the incidence of various adverse events were observed.To accumulate clinical experience and reference of anesthesia in obese patients.

Detailed description

Painless endoscopy is a popular method of endoscopic diagnosis and treatment.General intravenous anesthesia with propofol and fentanyl has been widely used in painless endoscopic diagnosis and treatment.However, the combined application of the two has an obvious respiratory central inhibitory effect, resulting in a decrease in blood oxygen saturation in patients, especially in obese and elderly patients, who are more prone to a sudden decrease in blood oxygen, and even life-threatening.Due to the potential risk of upper airway obstruction in some obese patients, intraoperative hypopnea may occur during painless colonoscopy due to sedative and analgesic drugs.Causing the patient to be starved of oxygen.At present, there is no special oropharyngeal ventilation device for gastroenteroscopy.In recent years, a new type of oropharyngeal ventilation channel has been developed and applied in clinic.Compared with the traditional nasal catheter, the new oropharyngeal airway nasal mask can better fit the patient's face, ensure the internal air tightness of the nose mask, and maximize the oxygen supply efficiency.Connecting the carbon dioxide outlet of the oral pharyngeal airway body can not only collect the exhaled gas of the patient, but also reduce the backflow of carbon dioxide gas.It can also be connected to a carbon dioxide detection device to monitor the partial pressure of carbon dioxide at the end of a patient's breath in real time.To evaluate whether a new type of oropharyngeal airway can reduce the incidence of hypoxia during painless gastroenteroscopy in general patients, the investigators present this study and investigate the safety and efficacy of the new type of oropharyngeal airway.
