Brief Summary

the(obstructivesleepapneahypoapneasyndromeOSAHS) is a kind of to sleep appear periodically in the process of syndrome characterized by partial or complete obstruction of upper respiratory tract.Patients with obstruction during the attack, faced with percutaneous arterial blood oxygen saturation (percutaneousarterialoxygensaturation, SpO2) to reduce the risk of can also trigger hypercapnia and cardiovascular dysfunction.The global incidence of OSAS is 4.0% in males and 2.0% in females .Sedative drugs inhibit the response of OSAS patients to external stimuli and may cause pharyngeal muscle collapse, leading to an increased risk of respiratory adverse events during painless gastroscopy in this population .In fact, OSAS has been identified as an independent risk factor for endoscopic hypoxia .Currently, there is no special oropharyngeal ventilation device used during gastroenteroscopy. Recently, a new type of oropharyngeal ventilation channel has been developed and applied in clinic.Compared with the conventional nasal catheter, the new oropharyngeal airway nasal mask can better fit the patient's face, ensure the air tightness inside the nose mask and maximize the oxygen supply efficiency. The carbon dioxide outlet connected to the oropharyngeal airway body can not only collect the patient's exhaled gas, but also reduce the backflow of carbon dioxide gas.It can also access carbon dioxide detection equipment to monitor the patient's PCO2 at the end of breath in real time .In order to evaluate whether the new oropharyngeal airway can reduce the incidence of hypoxia during painless gastroenteroscopy in general patients, the study was designed to investigate the safety and efficacy of the new oropharyngeal airway.

    1 minute after anesthesia induction

  • The dosage of additional drugs was recorded during the operation

    1 minute after anesthesia induction

  • The satisfaction of endoscopists was recorded

    Within 30 minutes after anesthesia awakening

  • Recorded adverse events

    1 minute after anesthesia induction

Study Arms (2)

Using a new oropharyngeal airway set

EXPERIMENTAL

In the new oropharyngeal airway group (experimental group), oxygen was continuously supplied through a catheter partially attached to the endoscopic bite before induction of anesthesia until the end of gastroenteroscopy

Device: Group using new oropharyngeal airway (experimental group)

The conventional endoscopic bite group was used

ACTIVE COMPARATOR

In the conventional endoscopic bite group (control group), oxygen was continuously supplied through a conventional nasal catheter before induction of anesthesia and until the end of gastroenteroscopy

Device: Endoscopic bite group (control group)

Interventions

Before anesthesia induction, study participants in the experimental group received 5-6L/min oxygen for about 1min through an endoscopic bite oxygen supply device, and anesthesia induction was administered with propofol 3mg/kg and sufentanil 7μg.Sufentanil was given at the beginning of pre-oxygen inhalation, and propofol was given 1min later. When participants achieved sufficient sedation (about BIS40), they were placed into the oropharyngeal airway through the endoscopic bite and began gastroscopy.Anesthetic maintenance was administered with a continuous pump of 5mg/kg·h propofol until completion of the examination

Using a new oropharyngeal airway set

Prior to induction of anesthesia, control study participants inhaled 5 to 6L/min of oxygen through a nasal catheter for approximately 1 minute.Anesthesia was induced by propofol 3mg/kg and sufentanil 7μg.Sufentanil was given at the beginning of pre-oxygen inhalation, and propofol was given 1min later. The endoscopic procedure began when the study participants reached sufficient sedation (about BIS40) and the ordinary endoscopic bite group reached sufficient sedation.Anesthetic maintenance was administered with a continuous pump of 5mg/kg·h propofol until completion of the examination.

The conventional endoscopic bite group was used
