简要总结
This study used sequential method（Dixon's up and douwn） to determine the effective dose of remiazolam combined with propofol in painless upper gastrointestinal endoscopy
详细描述
Remimazolam tosylate is a novel benzodiazepine drug that can be used for gastrointestinal sedation. However, some studies have reported that the sedative effect of using remimazolam alone is poor, and the patient's body movements are obvious, which affects the operation of endoscopists. Propofol, as a commonly used sedative drug, has good sedative effects, but has a high incidence of adverse events, especially cardiovascular system inhibition. Therefore, this study will explore the effective dose of remimazolam combined with propofol, reduce the adverse events of propofol and increase the sedative efficacy of remimazolam. This study only set up one study group, fixed the dosage of propofol, adjusted the dosage of Remimazolam to meet the appropriate sedation requirements for patients. Patients with successful sedation were judged to have a negative reaction, while patients with failed sedation were judged to have a positive reaction. A sequential chart was drawn based on the sedation situation until 7 positive negative reaction intersections were found, and the study ended

研究组 & 干预措施
remimazolam tosylate
The fixed dose of propofol in this study was 0.5mg/kg, with an injection time of 30 seconds. Subsequently, remimazolam was administered at an initial dose of 0.1mg/kg. After 1 minute of administration, sedation was evaluated using MOAA/S. When the MOAA/S score was ≤ 1, endoscopic examination could begin. If the patient did not show physical activity or coughing, sedation was considered successful, and the next patient's medication dose was reduced by 0.02mg/kg; On the contrary, if sedation fails, the next patient will receive an additional 0.02mg/kg of medication.
