When premature rupture of membranes occurs, amniotic fluid will leak intermittently, which can cause some pregnant women to worry about fetal hypoxia or even lack of fetal movement inside the womb. However, this concern is misguided. Although the amniotic fluid may leak intermittently when membranes rupture prematurely, new amniotic fluid is continuously produced to replenish it. Thus, the fetus will still be active within the uterus and fetal movements can still be felt. However, after premature rupture of membranes, it is crucial to monitor whether the frequency of fetal movements is normal. This is because the chances of fetal hypoxia or intrauterine infection can increase after membrane rupture, and monitoring fetal movements is one of the simplest and most effective ways to assess the fetal condition in the uterus. If a decrease in fetal movements is observed, it is imperative to promptly carry out fetal heart monitoring or assess the overall condition of the pregnant woman. If fetal hypoxia is confirmed, it may be necessary to terminate the pregnancy swiftly.
