NCT06304337

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Incidence of hypoxia (Spo2<90%,t>10s) and severe hypoxia (Spo2<85%) during anesthetic sedation

    The incidence of hypoxia (75%≤SpO2 \< 90%, \< 60s) and severe hypoxia (SpO2 \< 75% or 75%≤SpO2 \< 90%, ≥60s) during anesthesia was recorded,The time of intervention was half or disappearance of end-expiratory carbon dioxide and/or disappearance of thoracic fluctuation and/or SpO2 \< 95%, that is, open airway manipulation was taken successively until SpO2≥95%, and the last means of opening the airway was recorded.The means of opening the airway of the two groups were the same, including: 1) adjusting the oxygen flow;2) Lift the lower jaw;3) Mask ventilation (pull out the gastroscope if necessary);4) Tracheal intubation or laryngeal mask for ventilator assisted ventilation.

    during surgery

Secondary Outcomes (4)

  • The incidence of choking, reflux aspiration and laryngeal spasm were recorded

    during surgery

  • The dose of additional drugs during the operation

    during surgery

  • Endoscopist satisfaction

    within 30 minutes after surgery

  • Record adverse events that occur throughout the process

    during surgery

Study Arms (2)

Ordinary oral cushion set

NO INTERVENTION

Before anesthesia induction, patients in the experimental group received 5-6L/min of oxygen for about 1min through the endoscopic bite connecting oxygen supply device, and patients in the control group inhaled 5-6L/min of oxygen for about 1min through the nasal catheter.Both groups were anesthetised with propofol 3mg/Kg and sufentanil 7ug.Sufentanil was given at the beginning of pre-oxygen inhalation, and propofol was given 1min later. After the subjects achieved sufficient sedation (about BIS40), The ordinary endoscopic bite group began to perform endoscopic operation after sufficient sedation was achieved,In both groups, 5mg/Kg/h propofol was continuously pumped to maintain anesthesia until completion of the examination.

EXPERIMENTAL

Before anesthesia induction, patients in the experimental group received 5-6L/min of oxygen for about 1min through the endoscopic bite connecting oxygen supply device, and patients in the control group inhaled 5-6L/min of oxygen for about 1min through the nasal catheter.Both groups were anesthetised with propofol 3mg/Kg and sufentanil 7ug.Sufentanil was given at the beginning of pre-oxygen inhalation, and propofol was given 1min later. After the subjects achieved sufficient sedation (about BIS40), the new oropharyngeal airway group was placed into the oropharyngeal airway through the endoscopic bite and then began gastroscopy,In both groups, 5mg/Kg/h propofol was continuously pumped to maintain anesthesia until completion of the examination

Device: New oropharyngeal airway group

Interventions

Oropharyngeal airwayIt is composed of nasal plug, bite mouth, oropharyngeal passage, oxygen supply tube, rope and optional accessories carbon dioxide gas catheter and carbon dioxide collection tube.For patients undergoing endoscopic surgery/examination to prevent airway obstruction caused by backtongue fall, establish oropharyngeal airway for patients, and provide nasal oxygen at the same time, JK model can monitor oropharyngeal end-expiratory carbon dioxide collection.
