The cloudy amniotic fluid can be detected by ultrasound, but the nature of the cloudy amniotic fluid cannot be determined. The common understanding of cloudy amniotic fluid is that there are impurities in the amniotic fluid, or the amniotic fluid is not very clean, and after the water breaks the amniotic fluid is not a clear color, which can be seen by ultrasound, but ultrasound is not able to determine the specific composition of the cloudy amniotic fluid. The amniotic fluid is often divided into two types: 1, cloudy amniotic fluid caused by fetal feces: the fetal stool is discharged into the amniotic fluid, causing cloudy amniotic fluid, this is a pathological case of cloudy amniotic fluid, may be a manifestation of fetal hypoxia, distress, if fetal heart monitoring proves that the fetus does have signs of distress, it is necessary to perform a timely cesarean section to terminate the pregnancy; 2, cloudy amniotic fluid caused by fetal fat, hair: in general, if The amniotic fluid is cloudy because of the fetal fat and hair, which is a normal physiological reaction and does not require special treatment; ultrasound can detect cloudy amniotic fluid, which can alert the clinician, so that the clinician can determine whether the cloudy amniotic fluid has any specific impact on the fetus and whether it affects the growth and development of the fetus, taking into account the specific situation of the fetus.
