Prolonged pregnancy is another theme that deserves attention, since perinatal morbidity and mortality are slightly increased in gestations over 40 weeks if foetal assessment is not correctly performed [15]. Main risk factors that can be associated with prolonged pregnancy are related to low socioeconomic level of women, excessive weight gain during pregnancy and previous prolonged pregnancy [16]. Perinatal complications associated with prolonged gestations are foetal macrosomia, placental dysfunction, acute foetal distress, oligohydramnios, meconium emission and aspiration and perinatal death [15].
