Protracted Labor

Labor that takes longer than expected due to slow cervical dilation, weak or irregular contractions, a small maternal pelvis or large sized baby. To regulate and/or strenghthen contractions, pitocin may be given. If the mother's pelvis is too small to accompany the baby, a cesarean section may be necessary.
