1. Maternal and neonatal morbidity with prolonged labor The adverse maternal and neonatal morbidity association with prolonged labor has been demonstrated in numerous studies. An increase in maternal risk of post partum hemorrhage and endometritis has been associated with prolonged labor. Cheng et al demonstrated that the risk of post partum hemorrhage and endometritis significantly increased with increasing length of labor. Maghoma et al evaluated the latent phase of labor and found a similar increased risk in endometritis but also noted a significant risk in maternal sepsis with a prolonged latent phase of labor.
