When a woman is pregnant, the condition of amniotic fluid has a significant impact on the baby, as amniotic fluid represents the living environment of the fetus. Abnormal conditions of amniotic fluid are usually oligohydramnios, amniotic fluid leakage, and amniotic fluid contamination, which can cause harm to the fetus. So, why is amniotic fluid contaminated?
1. Meconium contamination: Many cases of amniotic fluid contamination are caused by fetal stool. When the amniotic fluid reaches a level of 3 contamination, it can harm the fetus. If it becomes more severe, it may endanger the survival of the fetus. Amniotic fluid contaminated with meconium usually appears green, cloudy, and less viscous.
2. Fetal fat: Fetal fat is also a common cause of amniotic fluid contamination, which mostly occurs around 39 weeks of pregnancy. However, amniotic fluid contamination caused by fetal fat is less harmful to the fetus.
3. Cholestasis: Bile may also accumulate in amniotic fluid, leading to contamination of the amniotic fluid. The main substances in amniotic fluid are fetal water, brittle hair, etc. If cloudy amniotic fluid is observed during ultrasound examination, it indicates that the fetal living environment is not very good.
4. When pregnant women suffer from certain diseases, amniotic fluid can also be contaminated. For example, progesterone anemia, hypertension, etc. In addition, amniotic fluid contamination can also occur when there is intrauterine hypoxia and developmental abnormalities in the fetus.
