What is the primary risk associated with prolonged rupture of membranes?

The primary risk associated with prolonged rupture of membranes is infection. When the amniotic sac ruptures, it creates a direct pathway for bacteria to enter the uterus, increasing the likelihood of infection for both the mother and the fetus. This condition, known as chorioamnionitis, can lead to complications such as premature labor, neonatal sepsis, and other serious health issues.

The risk of infection becomes especially significant if the membranes have been ruptured for an extended period, typically defined as more than 18 hours before labor begins. Vigilant monitoring and intervention are often necessary to mitigate this risk and ensure the safety of both the mother and the baby.

In contrast, while fetal distress, maternal hemorrhage, and placenta previa are all important considerations in obstetrical care, they are not the primary concern associated specifically with prolonged rupture of membranes.
