Labor that progresses too slowly may involve slow cervical dilation or movement of the fetus through the birth canal (protracted labor) or a complete pause in the labor's progress (arrested labor).
Causes of labor that is progressing too slowly include the following:
Fetus is too big to move through the birth canal (pelvis and vagina)
Birth canal is too small
Contractions of the uterus are too weak or not often enough to keep the fetus moving
Occasionally, contractions are too strong or close together
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.
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 or the birth canal is too small for the fetus to move through the birth canal, cesarean delivery is done.
