Using Internal Jugular Vein Ultrasound to Predict Low Blood Pressure After Spinal Anesthesia in Patients 65 and Older Undergoing Elective Surgery

What this Trial Is About

This research aims to assess how measurements of the internal jugular vein IJV obtained by ultrasound before surgery can predict the risk of low blood pressure hypotension after spinal anesthesia in older adults. Spinal anesthesia is commonly used in patients aged 65 and older, but this group is more prone to blood pressure drops due to age-related changes and decreased heart function. Identifying those at risk could improve care and safety during surgery. The study will include patients 65 years and older scheduled for elective surgery with spinal anesthesia. Before anesthesia, ultrasound will measure the IJV diameter, cross-sectional area, and collapsibility index while the patient lies down. During surgery, blood pressure and heart rate will be closely monitored for up to 90 minutes after spinal anesthesia to observe any hypotension. Participants will be grouped based on whether they develop hypotension or not. Participants will be involved in preoperative ultrasound scans and intraoperative monitoring of vital signs. Researchers will record blood pressure and heart rate before and after anesthesia and analyze if the ultrasound measurements can predict hypotension. The studys primary outcome is the occurrence of hypotension within 90 minutes after spinal anesthesia. This observational study will help evaluate the usefulness of IJV ultrasound as a noninvasive method to identify patients at risk during surgery.
