Emergence agitation (EA) is a transient, self-limited, non-fluctuating state of psychomotor excitement, which closely revolves around the emergence of general anesthesia. Uncontrolled EA during the recovery period increases the potential risk of injury to patients and medical staff, resulting in varying degrees of adverse consequences, such as elevated blood pressure, incision rupture, bleeding, cardio-cerebrovascular accidents and so on, leading to a great waste of resources. Accumulating scientific evidence indicates that the incidence of EA is related to the use of perioperative sedative drugs. As a novel ultra-short-acting benzodiazepines drugs, Remimazolam has been accepted for induction and maintenance of clinical anesthesia. Compared to traditional benzodiazepines drugs, Remimazolam combines the safety of midazolam with the effectiveness of propofol, and also has the advantages of acting quickly, short half-life, no injection pain, slight respiratory depression, independent of liver and kidney metabolism, long-term infusion without accumulation, and has a specific antagonist: flumazenil. This study aims to investigate whether perioperative sedation of Remimazolam besylate, propofol, and sevoflurane have different effects on the incidence of emergence agitation and hemodynamics in patients undergoing laparoscopic abdominal surgery.
