Brief summary
This study aims to evaluate the efficacy and safety of Remimazolam, either used alone or in combination with Propofol, for moderate sedation anesthesia during endoscopic therapies or examinations. Additionally, it seeks to explore whether their combination can further enhance the quality of patient anesthesia and recovery outcomes.
Detailed description
Objective This study aims to evaluate the efficacy and safety of Remimazolam, either used alone or in combination with Propofol, for moderate sedation anesthesia during endoscopic therapies or examinations. Additionally, it seeks to explore whether their combination can further enhance the quality of patient anesthesia and recovery outcomes. Methods The investigators will conduct a prospective, randomized, single-center study. Eligible patients will be randomly allocated into three groups: the first group receiving Propofol alone for moderate sedation anesthesia (control group), the second group receiving Remimazolam alone for anesthesia, and the third group receiving a combination of Propofol and Remimazolam for anesthesia. The investigators will record anesthesia depth (DSA values of BIS), heart rate, blood pressure, oxygen saturation, and other indicators during the procedure, as well as postoperative recovery time, time to consciousness recovery, oxygen desaturation, instances of inadequate anesthesia depth, intraoperative patient movement or recall, surgeon satisfaction, patient satisfaction, readmission rate within 14 days, complications, and length of hospital stay.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dose change | Perioperatively (during upper gastrointestinal endoscopy) | Change in Propofol dose ratio. (Record total dose, Duration, mg/h/kg) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to open eyes after stopping Propofol or Remimazolam. | The timer starts after the anesthetic is administered. | Eye open minutes after Propofol or Remimazolam stop. |
| Use of rescue medications during surgery. | During surgery | Rescue drugs are used during the operation |
| Analgesic dosage in the recovery room. | Observation period in the postoperative recovery room | Analgesic dosage in the postoperative recovery room. |
| Incidence of postoperative nausea and vomiting. | After returning to the ward from the recovery room until before breakfast on the first postoperative day. | Track postoperative nausea and vomiting episodes. |
| Pain Intensity (Visual Analog Scale, VAS) every 15 minutes in the recovery room for 1 hour after surgery. | Within 1 hour post-surgery. | Assessment of pain intensity using the Visual Analog Scale (VAS), where 0 represents no pain and 10 represents the worst possible pain. |
| Pain from the first injection of medication. | During the surgery (immediately after the first injection). | Assessment of pain intensity caused by the first injection of medication, measured using the Visual Analog Scale (VAS) from 0 to 10. |
| Recall of surgery events. | On postoperative day 1 (within 24 hours after surgery). | Recall events during surgery. |
| Analgesic dosage in the ward. | The patients were followed up from the time they returned to the ward after surgery to the first day after surgery. | The dosage of analgesics used in post-operative wards. |
