Whether the amniotic fluid contamination can be delivered by normal delivery cannot be generalized. In clinical practice, some pregnant women have normal amniotic fluid at the beginning, but suddenly have cloudy amniotic fluid near the time of delivery. If a pregnant woman can deliver quickly and her fetal heart rate is normal, she can have a normal delivery through active treatment. If a pregnant woman is not in labor and her amniotic fluid becomes cloudy or her fetal heart rate decelerates frequently, even if the pregnant woman has a strong desire to deliver, the doctor needs to assess the risk and give medical advice, so whether amniotic fluid contamination can be delivered by normal delivery needs specific analysis.
