Abstrakt:	Purpose: Remimazolam is a novel short-acting benzodiazepine used for sedation and general anesthesia. This study aimed to evaluate the efficacy and safety of remimazolam besylate in elderly patients who underwent diagnostic gastrointestinal endoscopy. Patients and Methods: A total of 120 patients aged 60-75 years were randomly allocated to one of two groups. Remifentanil 0.3μg/kg was used for analgesia. Patients were administered remimazolam besylate 7 mg (R group) or etomidate 0.1 mg/kg combined with 1% propofol 0.5 mg/kg (EP group) for induction, supplemental repeated doses were given as needed. Some time metrics, vital signs, adverse events were evaluated. Patients' Mini-cog score and recovery questionnaires were compared. Results: Compared to the EP group, the induction time was slightly longer in the R group (1.50 VS 1.15 minutes) (P<0.05), the time spent in the post-anesthesia care unit (PACU) was shorter (15.17 VS 17.40 minutes) (P<0.05). Compare with EP group, SBP was lower in R group at T15 and T25 time point, but heart rate was higher in T2, T3, T5 (P< 0.05). The Mini-Cog score was higher after the procedure (2.83 VS 2.58) (P<0.05). The incidence of respiratory adverse events was higher in the EP group than R group (18.3% VS 5.0%, P < 0.05). The most common adverse event in R group was hiccups. The sedation satisfaction rate and degree of amnesia were higher in the R group (66.7% VS 11.7%) (P < 0.05), and the effect on patient's life within 24 hours was lower (12.0% VS 30.5%) (P < 0.05). Conclusion: The safety and efficacy of remimazolam besylate are not inferior to those of etomidate combined with propofol, rendering it a safe option for sedation during gastrointestinal endoscopy in ASA I-II elderly patients, but care should be taken to monitor the occurrence of hiccups. Competing Interests: The authors report no conflicts of interest in this work. (© 2024 Zhang et al.)
