Femoral Vein Collapsibility Index and Post-Spinal Hypotension in Pregnant Women: Impact of Position

This study aims to improve the safety of spinal anesthesia for pregnant patients undergoing elective cesarean delivery. Specifically, the investigators are investigating whether ultrasound measurements of a vein in the groin (the right common femoral vein, or RCFV) can help predict the risk of low blood pressure (hypotension) after spinal anesthesia. The main question it aims to answer is: Can femoral vena cava collapsibility index predict post-spinal hypotension in pregnant women in left lateral tilt position? Before receiving spinal anesthesia, participants will undergo a brief and painless ultrasound examination of the RCFV in the groin area while lying in a specific position."
