Ropivacaine and Fentanyl for Labor Epidural Initiation

Summary

This study is being done to determine the most effective dose of medicine to use to initially provide effective pain relief within the first 30 minutes of receiving an epidural for pain labor during labor. The study team will also study any side effects related to the epidural medication and patients' satisfaction with the quality of pain relief after receiving the epidural.
