Background: Hemodynamics describes the physiological mechanisms that regulate blood flow throughout the body. Spinal anesthesia is a regional anesthetic technique in which medication is injected into the subarachnoid space. Hemodynamic changes after spinal anesthesia are common intraoperative events.

Purpose: This study aimed to determine the hemodynamic profile before and after spinal anesthesia in surgical patients.

Method: This quantitative descriptive study used a cross-sectional design and purposive sampling, a non-probability sampling technique. The sample consisted of 80 patients. Most respondents were female, and the largest age group was 56–65 years.

Results: Before spinal anesthesia, blood pressure was most frequently in the hypertensive category, while mean arterial pressure (MAP), respiratory rate, pulse rate, and oxygen saturation were generally within normal or stable ranges. After spinal anesthesia, blood pressure distribution shifted, with more patients in the normal category. MAP, respiratory rate, pulse rate, and oxygen saturation remained stable.

Conclusion: Spinal anesthesia may lower blood pressure by blocking sympathetic nerve fibers, reducing systemic vascular resistance and cardiac preload because of venous pooling in the legs and viscera due to vasodilation. Periodic hemodynamic monitoring, particularly of blood pressure, is therefore required during surgery.
