Abstract:
Objective:To evaluate the sedative efficacy of remimazolam in outpatients undergoing curettage.Methods:Eighty outpatients, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, aged ≥18 yr, undergoing curettage, were divided into 2 groups according to the random number table method: remimazolam group (group R, n=41) and propofol group (group P, n=39). Anesthesia was induced with alfentanil 10 μg/kg injected intravenously in two groups, and in addition remimazolam 7 mg was intravenously injected in group R, and propofol 1.5 mg/kg was intravenously injected in group P. If the Modified Observer′s Assessment of Alertness/Sedation score ≥3 or the patient could not tolerate the surgical procedure, remimazolam 2.5 mg was given for rescue sedation in group R and propofol 0.5 mg/kg was given for rescue sedation in group P, and alfentanil 1 μg/kg was given as rescue analgesic.The onset time of sedatives, time to eye opening, emergence time and time to discharge were recorded.The success of sedation, intraoperative BIS value, requirement for rescue medications, and occurrence of adverse reactions were recorded. Results:The intraoperative BIS values were maintained at 61-72 and 40-64 in group R and group P, respectively.The success rate of sedation was 95% in group R and 100% in group P, and there was no significant difference between the two groups ( P>0.05). Compared with group P, the rate of rescue sedative agents used and rate of rescue alfentanil given were significantly increased, the onset time of sedative agents was significantly prolonged, the incidence of postoperative nausea and vomiting was increased, and the incidence of respiratory depression and injection pain was decreased in group R ( P<0.05 ). Conclusion:Remimazolam (given according to the instructions) is safer when used for outpatient curettage, but it can only maintain a light sedation status, and the sedative efficacy is inferior to propofol.
