HYPERTENSION, INFILTRATION
Hypertensive patients were defined as individuals who had a prior diagnosis of hypertension before admission or who met the diagnostic criteria for hypertension after admission, regardless of their medication use or pattern. A preoperative visit was routinely performed on the day before the operation to explain the study to the patient and obtain written informed consent from the patient. Baseline blood pressure was measured by averaging three consecutive blood pressure measurements. After entering the operating room, the electrocardiogram, pulse oxygen saturation, noninvasive blood pressure, and the bispectral index (BIS) were monitored, and peripheral venous access was routinely obtained. Radial artery catheters were inserted under lidocaine infiltration anesthesia, and arterial blood pressure was continuously monitored and recorded using the arterial sensor once a minute.In the remimazolam group, general anesthesia was induced with intravenous injections of remimazolam (Jiangsu Hengrui Medicine Co. Ltd., approval number: 210721AK) at 0.3 mg/kg, sufentanil at 0.4 µg/kg, and cisatracurium at 0.2 mg/kg. Anesthesia was maintained with remimazolam (0.3 mg/kg/h), remifentanil (5 µg/kg/h), and sevoflurane (0.5–1 MAC). In the propofol group, general anesthesia was induced with intravenous injections of propofol (Sichuan Guorui Pharmaceutical Co. Ltd., approval number: H20091713) at 2 mg/kg, sufentanil at 0.4 µg/kg, and cisatracurium at 0.2 mg/kg. Anesthesia was maintained with propofol (2 mg/kg/h), remifentanil (5 µg/kg/h), and sevoflurane (0.5–1 MAC). The injection speed of remimazolam and propofol was controlled within 40 s during the induction of anesthesia [
