NCT06721195

Brief Summary

This study aims to investigate the incidence of euphoria induced by remimazolam during gastrointestinal endoscopy and explore its related factors. Gastrointestinal endoscopy, a minimally invasive procedure, often causes discomfort and anxiety for patients. Remimazolam, a short-acting benzodiazepine, is increasingly used for sedation during these procedures due to its rapid onset, short metabolism, and controlled cardiorespiratory effects. This cross-sectional study will evaluate the effect of remimazolam on patient comfort, cooperation, and satisfaction during endoscopy, aiming to optimize sedation protocols and improve clinical outcomes.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Euphoria Induced by Remimazolam

    he occurrence of euphoria in patients undergoing sedation with remimazolam during gastrointestinal endoscopy procedures (gastroscopy, colonoscopy, or both). Euphoria is assessed using the ARCI-MBG scale. A positive result is defined as an increase in the ARCI-MBG score post-procedure compared to pre-procedure.

    From pre-procedure baseline to 2 hours post-procedure (Euphoria is assessed at two time points: immediately before sedation and two hours after the procedure, upon full recovery.)

Secondary Outcomes (1)

  • factors Associated with Euphoria Induced by Remimazolam

    From pre-procedure baseline to 2 hours post-procedure (Factors are collected before the procedure, during sedation, and 2 hours post-procedure, upon full recovery.)

Study Arms (1)

Remimazolam Sedation Group

his cohort includes patients undergoing painless gastrointestinal endoscopy (gastroscopy, colonoscopy, or both) who receive sedation with remimazolam. The study aims to evaluate the incidence of euphoria induced by remimazolam and explore related factors. All patients receive sedation according to standard clinical guidelines, including pre-procedural sufentanil and lidocaine gel for oral preparation, followed by remimazolam for induction and maintenance. Data collected include demographic characteristics, pre- and post-procedure euphoria scores assessed using the ARCI-MBG scale, perioperative safety indicators, and patient satisfaction.

Drug: Remimazolam for Gastrointestinal Endoscopy Sedation

Interventions

This intervention involves the use of remimazolam, a short-acting benzodiazepine, for sedation during gastrointestinal endoscopy procedures (gastroscopy, colonoscopy, or both). Remimazolam is administered intravenously at an initial dose of 0.2-0.3 mg/kg, followed by additional doses of 2.5 mg as needed to maintain adequate sedation (MOAA/S score ≤ 2). Unlike other benzodiazepines, remimazolam is rapidly metabolized by plasma esterases, resulting in a quick onset and recovery with minimal respiratory and cardiovascular depression. The study specifically evaluates the euphoria-inducing potential of remimazolam, using the ARCI-MBG scale pre- and post-procedure to assess its effect on patient comfort and satisfaction.

Sampling MethodNon-Probability Sample
Study Population

The study population includes adult patients aged 18 to 65 years undergoing painless gastrointestinal endoscopy (gastroscopy, colonoscopy, or both) at a tertiary hospital. Participants must meet the inclusion criteria, such as ASA I-II classification and BMI between 18 and 28 kg/m². Patients are recruited from routine endoscopy appointments and provided written informed consent prior to participation. Exclusion criteria include severe comorbidities, psychiatric disorders, substance abuse, pregnancy, or recent participation in other clinical studies.

You may qualify if:

  • Adults aged 18 to 65 years, regardless of gender.
  • Patients scheduled for routine painless gastrointestinal endoscopy, including gastroscopy, colonoscopy, or both.
  • ASA physical status classification: I or II.
  • BMI between 18 kg/m² and 28 kg/m².
  • Anticipated procedural duration of no more than 30 minutes.
  • Patients who have provided written informed consent after understanding the study purpose, procedures, and potential risks.

You may not qualify if:

  • History of psychiatric disorders such as schizophrenia, bipolar disorder, or personality disorders, or a history of alcohol, stimulant, or other substance abuse.
  • Known allergies or intolerance to any medication used in the study, including remimazolam, sufentanil, or benzodiazepines.
  • Patients requiring complex endoscopic procedures (e.g., ERCP, endoscopic submucosal dissection, endoscopic mucosal resection, or peroral endoscopic myotomy).
  • History of severe hepatic or renal disease.
  • Pregnant or lactating women.
  • Participation in another clinical study within the past three months.
  • Any condition or factor that, in the investigator's judgment, makes the patient unsuitable for participation in the study.
