Efficacy and Safety of Remimazolam Tosylate for Sedation in Gastroscopy

A Multicenter, Randomized, Single-blind, Parallel Controlled Clinical Study on the Efficacy and Safety of Remimazolam Tosylate for Sedation in Gastroscopy

Propofol is the most commonly used intravenous anesthetic for painless gastroscopy, but propofol significantly inhibits the respiratory and circulatory systems. Therefore, the incidence of intraoperative hypoxemia and hypotension is high. Remazolam tosylate is an ultra-short-acting benzodiazepine drug, which has a mild inhibitory effect on the respiratory and circulatory systems and has anterograde amnesia. These advantages make remazolam tosylate very likely to replace propofol in painless gastroscopic anesthesia.

Inclusion Criteria:

- 1)18≤age≤60 years old, no gender limit; 2) Patients receiving routine gastroscopy diagnosis and treatment; 3) ASA score is I or II; 4) 18 kg/m2<BMI<28kg/m2； 5) It is estimated that the operation time of gastroscope will not exceed 30 minutes; 6) Clearly understand, voluntarily participate in the research, and be signed and informed consent.
