With an arrest of the active phase,the progress of labour has stopped.This patient has not had any anticipated cervical change,indicating an arrest of labour.In the nulliparous woman,a prolonged latent phase typically would last over 20 hours.A protracted active phase,the first or second stage of labour,would be prolonged (slow dilation: <1.2 cm/hr in a nullipara and <1.5 cm/hr in a multipara).With protracted descent,the fetus would fail to descend at an anticipated rate during the deceleration phase and second stage of labour.
