Acceleration of labour is sometimes called augmentation of labour. If labour is taking a long time and is not progressing at the usual rate you may be offered treatment to speed up the dilation of your cervix and strengthen your contractions. You may be given oxytocin through a drip to help your womb contract more strongly. If your waters have not broken then your midwife or doctor may also suggest having the membranes ruptured to speed up labour.
