With the aging of the population, increasing numbers of elderly patients need surgical treatment. Hypertension is very common in elderly patients. Because elderly patients with hypertension generally have poor vascular elasticity, declining cardiovascular reserve function, and weakening of compensatory ability, hemodynamic fluctuations are likely to occur during anesthetic induction in these patients, potentially inducing serious complications. Propofol is a widely used sedative drug in the clinical setting and has the advantages of a short half-life and rapid recovery. However, the use of conventional doses of propofol in elderly patients is associated with a risk of complications such as hypotension, bradycardia, and arrhythmia [Remimazolam is a new type of anesthetic that has raised widespread concern. Remimazolam is an ultra-short-acting intravenous benzodiazepine sedative/anesthetic with the pharmacological properties of rapid onset, rapid recovery, and relatively small effects on hemodynamics [
