Flumazenil or placebo was administered for reversal. Hemodynamics were monitored via Continuous Non-Invasive Arterial Pressure (CNAP). The primary outcomes were hypotension incidence and hemodynamic parameters [mean arterial pressure (MAP), heart rate (HR), cardiac output (CO), and systemic vascular resistance (SVR)]; secondary outcomes included the incidence of other adverse events and recovery time.Results: Group R exhibited significantly lower incidences of hypotension (72.7% vs 37.3%, p < 0.001) and bradycardia (16.4% vs 7.3%, p = 0.037), alongside reduced vasopressor requirements (ephedrine: 3.760 ± 4.133 vs.1.850 ± 3.121, p < 0.001; metaraminol: 0.101 ± 0.208 vs 0.045 ± 0.144, p = 0.012). Both groups exhibited decreased MAP, CO, and SVR at the time point of endoscope entry (T1) compared to 2 minutes before anesthesia induction (T0), while HR reduction was significant only in group P (p < 0.001 vs p = 0.084 in group R). From T1 through 15 minutes post-procedure (T4), group R maintained higher MAP and HR than group P (p < 0.05). Remimazolam was associated with shorter recovery time (p < 0.001), lower rates of respiratory depression (p = 0.002), but higher rates of body movements (p < 0.001) and cough (p = 0.001).Conclusion: Remimazolam provides superior hemodynamic stability and faster recovery compared to propofol in elderly hypertensive patients undergoing gastroenteroscopy, establishing it as a safer sedation option for this vulnerable patient population.Trial Number and Registry Url: Registration number, ChiCTR2400083757; https://www.chictr.org.cn/showproj.html?proj=214795.Keywords: remimazolam, propofol, elderly hypertensive patients, gastroenteroscopy |
