Hypertension is a common cardiovascular disease in China, with a prevalence of 44.7%, and its prevalence is gradually increasing every year [Propofol is the most commonly used intravenous anesthetic agent in clinical practice due to its rapid onset and recovery, short continuous infusion half-life, and complete awakening. However, because of its inhibitory effect, particularly on the respiratory and circulatory systems, propofol has been designated as a drug with a narrow therapeutic index [Remimazolam is a novel, ultra-short-acting benzodiazepine with sedative and hypnotic effects [However, relevant randomized controlled studies to validate the efficacy and safety of remimazolam in hypertensive patients are still lacking. Therefore, this study aimed to evaluate the hemodynamic stability, occurrence of adverse events, and quality of postoperative recovery after the administration of remimazolam in general anesthesia for hypertensive patients undergoing breast cancer surgery. Propofol was administered to the control group.
