This study is designed to determine the minimum effective dose (ED90) of infusions of
oxytocin for the prevention of uterine atony / postpartum hemorrhage and the need for
additional uterotonics, in low risk parturients presenting for an elective CD.
The primary outcome measure is the response of effective uterine contraction as either
satisfactory or unsatisfactory as determined by the obstetrician blinded to the oxytocin
infusion dose. Secondary outcomes will include need for additional uterotonics, calculated
intra-operative blood loss and presence of oxytocin related adverse effects.
