Abstract
Spinal anesthesia with hyperbaric bupivacaine is a common anesthetic technique used in various surgical procedures. However, its effects on hemodynamic parameters can vary between hypertensive and normotensive patients. This observational study aims to compare the hemodynamic responses, including blood pressure and heart rate, following spinal anesthesia in these two patient groups. A prospective observational study was conducted on 120 adult patients undergoing elective lower abdominal or lower limb surgery under spinal anesthesia with hyperbaric bupivacaine. The patients were divided into two groups: hypertensive (n=60) and normotensive (n=60), based on preoperative blood pressure measurements. Hemodynamic parameters, including systolic and diastolic blood pressure, mean arterial pressure and heart rate, were recorded at baseline, immediately after the administration of anesthesia and subsequently at 5‐minute intervals for the first 30 minutes, followed by 15‐minute intervals for up to one hour. The study found that hypertensive patients exhibited a greater decrease in systolic and diastolic blood pressure compared to normotensive patients following spinal anesthesia. The mean arterial pressure also decreased more significantly in the hypertensive group. However, heart rate changes were not significantly different between the two groups. These findings suggest that hypertensive patients are more prone to hemodynamic instability following spinal anesthesia. Hypertensive patients undergoing spinal anesthesia with hyperbaric bupivacaine may experience more pronounced decreases in blood pressure, highlighting the need for careful intraoperative monitoring and management. These results underscore the importance of individualized anesthetic management in patients with pre‐existing hypertension to ensure patient safety.
