Question: 1 / 565

What is the most likely cause of postmaturity syndrome?

Increased placental blood flow

Decreasing uteroplacental function

Postmaturity syndrome is primarily caused by decreasing uteroplacental function. In cases of postmaturity, the placenta may start to age and function less effectively as the pregnancy extends beyond the typical gestational period. This decline in placental function can lead to inadequate oxygen and nutrient transfer to the fetus, potentially resulting in complications such as fetal distress or a reduced amniotic fluid volume.

Additionally, when the placenta is not functioning optimally, it can contribute to further complications for both the mother and the baby. It’s crucial for midwives and healthcare providers to closely monitor pregnancies that extend beyond 42 weeks to mitigate potential risks associated with this syndrome, including stillbirth, macrosomia, and meconium aspiration. Understanding these dynamics is essential for providing appropriate care and interventions in postmature pregnancies.
