After pregnancy, maternity checkups are routinely done, and there are many of them in order to protect the health of the expectant mother and the baby. Among them, ultrasound is essential. Can you read the report card of ultrasound? Do you understand the values on it? One of the issues that pregnant moms are very concerned about is amniotic fluid. So today we will talk about those things about amniotic fluid. Where does amniotic fluid come from? Amniotic fluid in the early stages of pregnancy is mainly the liquid that seeps through the membranes of the fetus from the pregnant mom’s maternal serum. In the middle of pregnancy, the baby will have urine formed, and at this time, the baby’s urine is the main source of amniotic fluid. So doesn’t amniotic fluid get more and more, as our baby reaches full term, the baby swallows the amniotic fluid then keeps our amniotic fluid volume basically in balance. Amniotic fluid is constantly exchanged within the amniotic cavity to keep the amount of amniotic fluid relatively constant. What does amniotic fluid look like? In early pregnancy, amniotic fluid is a clear, colorless liquid. In late pregnancy, the amniotic fluid may be slightly cloudy, opaque, and sometimes there are small flakes floating in the amniotic fluid, such as fetal hair, fetal fat, and some epithelial cells shed by the fetus. Amniotic fluid is also contaminated with color, according to the degree of different, amniotic fluid pollution is divided into three degrees: I degree of amniotic fluid pollution, amniotic fluid was light green, amniotic fluid is relatively thin, II degree of amniotic fluid contamination, amniotic fluid was dark green or yellowish green. III degree of amniotic fluid contamination, the amniotic fluid into a brownish-yellow color changes, thick, suggesting that the baby has a lack of oxygen may be. The contamination of amniotic fluid is related to the time and amount of meconium expelled from the baby. What is the function of amniotic fluid? Amniotic fluid protects the fetus. Amniotic fluid protects the baby from being squeezed, prevents adhesions in the limbs, and maintains temperature. Amniotic fluid also protects the mother’s body and reduces the discomfort caused to the mother due to fetal movement. After labor, amniotic fluid also lubricates the reproductive tract, reducing bacteria in our reproductive tract and decreasing the chance of infection.
