What is the primary danger associated with placental abruption?

The primary danger associated with placental abruption is compromised fetal perfusion. In this condition, the placenta detaches prematurely from the uterine wall, which can lead to significant disruption in the supply of oxygen and nutrients to the fetus. This detachment can compromise the placenta's ability to function effectively, resulting in decreased blood flow and oxygen delivery to the developing fetus.

While excessive bleeding is a serious concern with placental abruption, particularly for the mother, the most immediate threat to the baby is the lack of perfusion. If the fetus does not receive adequate blood flow, it can suffer from hypoxia, leading to potential long-term neurological damage or even fetal demise if the situation is not resolved promptly. The other options, such as infection or uterine rupture, are less directly associated with the immediate effects of placental abruption compared to the critical issue of fetal perfusion.
