In early pregnancy, the amniotic fluid is colorless and transparent, and the ultrasound shows an echogenic dark area with good sound transmission. With the development of the fetus, the amniotic fluid becomes cloudy and opaque in late pregnancy, and fine strong echogenic dots are seen floating in the amniotic fluid under the ultrasound, and the amniotic fluid is pale milky white during delivery. It is because the amniotic fluid is mixed with a small amount of flakes, the most common being fetal fat, as well as epithelial cells shed by the fetus, fine hair, hair, and a small amount of white blood cells, which are all normal manifestations. If the fetal heart is good, no special treatment is needed. However, if the fetal heart monitoring indicates unresponsive fetal heartbeat, too fast fetal heartbeat or even frequent decelerations, and the fetal heartbeat does not improve after oxygenation and changing position, it is a sign of fetal hypoxia. If not actively treated, when the fetus is hypoxic, the anal sphincter relaxes leading to defecation, and the fetal stool is discharged into the amniotic fluid, which is expressed as yellow or yellow-green, and the amniotic fluid is cloudy should be actively terminated as soon as possible.
