NCT02271100

Brief Summary

This study is intended to determine whether ultrasound imaging can improve the ability to place a spinal or epidural needle in obstetric anesthesia. By evaluating the use of ultrasound for the placement of epidural catheters the investigators hope to answer two questions: 1\. How does the traditional technique based on palpation compare to one using ultrasound to place an epidural catheter? 2. Does ultrasound reduce one potential risk in epidural placement?
