Conditions

Anesthesia Induction

Brief summary

The goal of this clinical trial is to compare the performance difference between trained model and clinical professionals in anesthesia control during gastrointestinal endoscopy. The participants would include adults aged between 18-65 years old with ASA scores I-II. The main questions it aims to answer are: * Can AI model successfully and safely perform anesthesia during gastrointestinal endoscopy? * Researchers hypothesis that anesthesia performed by professionals is not inferior to those performed by AI model. The researchers will compare the results of the AI group with the traditional group to see if both groups have similar success rates in performing anesthesia. Participants will fast for 8 hours before the procedure, and drinking water will be prohibited for 2 hours after taking the intestinal purgatives.

Interventions

During gastrointestinal endoscopy, anesthesia will be induced using ciprofol, and controlled by an AI model.

Anesthesia will be induced using ciprofol, and controlled by experienced anesthesiologists.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of hypoxemiaDuring procedureHypoxemia is defined as blood oxygen saturation below 92% at any time.

Secondary

MeasureTime frameDescription
Lowest value of blood oxygen saturationDuring procedure
Induction and maintenance doses of anesthesiaDuring procedureDoses are recorded in mg/kg/h. The induction period is defined as the interval from the start of anesthesia to the first BIS value below 60. The maintenance period is defined as the interval from the first BIS value below 60 to the end of the drug infusion.
Induction timeDuring procedureThe time interval from the start of drug administration to the first BIS ≤ 1.
Complete recovery timeDuring procedureTime interval from cessation of anesthetic agents to BIS \> 80.
Area under curve of hypoxemiaDuring procedureThe area where SpO2 is below 92%.
Counts of body movementDuring procedure
Dose of norepinephrineDuring procedure
Duration of colonoscopyDuring procedure
Ciprofol related adverse reactionsDuring procedureIncluded sinus bradycardia, dizziness
Incidence of hypotensionDuring proceduresystolic blood pressure \< 90 mmHg or a 30% decrease from baseline lasting longer than 2 minutes
