Perioperative Outcomes in Hypertensive Patients

Data to be evaluated include patient demographics and perioperative outcomes. Demographic characteristics included gender, age, body mass index (BMI), hypertension, diabetes, arrhythmia, ASA score, hormone levels, tumor side, tumor size and CT findings. Perioperative indicators included operation Time, pneumoperitoneum time, estimated blood loss (EBL), hemodynamic instability (HI), time to ambulation, time to oral food, time to removal of drainage, postoperative hospital stay, complications, and BP improvement rate.
The ASA score was used to evaluate the patient’s tolerance to anesthesia. Complications were classified according to the Clavien-Dindo classification (10 (link)). HI was defined as intraoperative BP >180 mmHg or mean arterial pressure <60 mmHg (11 (link)). BP improvement was defined as a decrease in BP after surgery or a decrease in the dose or type of antihypertensive medication taken (12 (link)).
