Summary

This study will check if measuring the jugular vein in the neck with ultrasound and using a standard pulse oximeter on the finger can predict which women will have a dangerous drop in blood pressure after receiving spinal anesthesia for a planned C-section. About 110 women having planned C-sections will be observed. The goal is to find a simple way to identify high-risk patients early, so doctors can take steps to prevent complications.
