Summary
The study aims to assess whether the transverse diameter of the right common femoral vein (RCFV) in the inguinal region could reflect the degree of post-spinal hypotension during elective orthopedic surgery.
Detailed description
Spinal anesthesia is commonly used in orthopedic procedures but often results in hypotension, particularly in elderly patients due to reduced cardiovascular reserve and impaired autonomic function. Ultrasound measurement of the right common femoral vein (RCFV) diameter has recently been proposed as a simple, non-invasive marker of intravascular volume status and a potential predictor of spinal anesthesia induced hypotension. To date, most evidence comes from obstetric populations undergoing cesarean delivery, limiting its applicability in other high-risk groups.
