Labor dystocia is a leading indication for cesarean section worldwide [26–31]. Several publications have linked a number of well-known risk factors for an operative intervention among otherwise low-risk women [29–31]. In this work we have studied some of these risk factors, as well as their relation to the metabolic status of the uterus presented as the AFL value. Our results show that AFL is a new predictor of labor outcome in arrested labors. If a high AFL level is present when augmentation starts, the likelihood of an operative intervention increases 4.5 times irrespective of the levels of the other known risk factors (Table 4).
