NCT01425762

Brief Summary

This is a randomized controlled study that will place patients into a "choice" and a "no choice" group. The choice group will be able to choose between receiving 100 mcg or 200 mcg intrathecal morphine. The no choice group will be randomized to receive either 100 mcg or 200 mcg of intrathecal morphine. Following casarean delivery, pain scores will be measured at 3, 6, 12, 24, and 36 hours.
