One study group will follow an oxytocin protocol which is incremental until 5 cm dilation and then maintained at the same level throughout labor. The second arm will follow an oxytocin protocol also incremental, but then discontinued once the cervix is 5 cm. The primary outcome will be the rate of cesarean delivery between the groups. Secondary outcomes to be evaluated will include duration of the labor, fetal heart rate abnormalities, and frequency of uterine hyperstimulation, maternal and neonatal outcomes.
