Registration Number
NCT02063568
Lead Sponsor
Duke University
Brief Summary

The purpose of this study is to evaluate the differences in blood clotting seen in healthy patients given two different doses of oxytocin following cesarean delivery. The secondary objectives are to evaluate changes in blood pressure, rates of nausea and vomiting, and differences in blood loss with the two separate doses of oxytocin.
