Compare Efficacy of Oxytocin Administrations on Postpartum Uterine Contractility

Study Overview
=================
Brief Summary
-----------------
This is a Phase I open-label, parallel-group clinical study in healthy term pregnant females undergoing a caesarean section. Two administrations of oxytocin will be tested, after which uterine contractility will be assessed.
