Causes of labor that is progressing too slowly include the following:
Doctors estimate the size of the fetus and birth canal and check the fetus’s position. They also check the strength and timing of contractions. These factors determine treatment.
If the birth canal is big enough for the fetus but labor is not progressing, the woman is given oxytocin intravenously to stimulate the uterus to contract more forcefully. If oxytocin is unsuccessful, a cesarean delivery may be necessary. Or if the baby is already in position to be delivered, a vacuum extractor or forceps may be used instead.
If the fetus is too big, cesarean delivery is done.
