Coagulation Changes With Oxytocin
Conditions
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.
