Summary: The relationship between amniotic fluid and the fetus is very close, just like a fish cannot live without water. The amniotic fluid provides an ideal living environment for the growth and development of the fetus throughout pregnancy, thereby ensuring the metabolism of the fetus and the balance of water in the amniotic fluid and the relationship between the fetus and the fetus. Very close, just like fish cannot live without water, amniotic fluid provides an ideal living environment for the growth and development of the fetus throughout pregnancy, thus ensuring the metabolism of the fetus and the balance of water. Oligohydramnios can occur at any stage of pregnancy, but is more common in the third trimester. Amniotic fluid less than 300 ml in late pregnancy is considered oligohydramnios. It is mostly caused by placental dysfunction or fetal congenital renal malformations.
Oligohydramnios often causes the following harm to the fetus
1. If oligohydramnios occurs in early pregnancy, the fetal membranes will stick to the fetus, causing severe fetal malformations.
2. If it occurs in the second and third trimesters of pregnancy, the buffering effect of amniotic fluid disappears, and the pressure of the uterus can directly act on the fetus, causing torticollis, hunched back, megagnathia, hand and foot deformities, etc. The fetal chest wall can be compressed, affecting the expansion of the lungs, leading to lung hypoplasia and a significant increase in the incidence of respiratory distress syndrome after birth.
3. Oligohydramnios during delivery will cause compression of the fetal umbilical cord during uterine contractions, and the incidence of intrauterine distress or neonatal asphyxia will also be significantly increased. If the amniotic fluid is turbid at the same time, it can cause aspiration pneumonia or airway obstruction in newborns and increase neonatal mortality.
Oligohydramnios can also have adverse effects on pregnant women. During pregnancy, pregnant women often feel abdominal pain when the fetus moves because the fetus is close to the uterine wall. During childbirth, the uterus contracts violently and the cervix expands slowly, often resulting in prolonged labor. Prolonged labor due to fetal distress increases the chance of maternal operative delivery.
How do pregnant women know if they have low amniotic fluid?
Most pregnant women with oligohydramnios will not experience obvious discomfort, so it is usually discovered through a doctor\’s physical examination or ultrasound during a pregnancy check-up.
However, some expectant mothers may feel that the growth rate of their belly has slowed down, and the feeling of fetal movement is more obvious than before. Sometimes fetal movement can cause significant abdominal pain. This is due to the loss of the buffering effect of amniotic fluid, and the fetal momentum directly acts on the local uterine wall, stimulating uterine contraction.
During prenatal examination, it is often found that the uterine height and abdominal circumference are significantly smaller than the corresponding menopausal weeks. At this time, doctors often recommend pregnant women to have a B-ultrasound examination to accurately estimate the amount of amniotic fluid.
Pregnant hypertension, diabetes, kidney disease, lupus erythematosus and other diseases can also cause oligohydramnios. Therefore, for these pregnant women, regular ultrasound examinations should be performed to detect oligohydramnios in time.
Let’s take a look at what pregnant women should do if their amniotic fluid is low.
What should pregnant women do if their amniotic fluid is low?
For patients with oligohydramnios, in addition to the treatment of maternal diseases, there are no abnormalities in the fetus after examination, and the pregnant woman has no serious complications. at the doctor\’sUnder guidance, the amount of amniotic fluid can be increased by drinking water quickly. Pregnant women who are not in labor but have insufficient amniotic fluid can drink 2000 ml of water within 2 hours. If the requirements are still not met, the above method can be repeated. This method is safe, effective, simple and easy to implement. Because drinking water can promote blood circulation in pregnant women, it can also increase indirect circulation between the uterus and placenta, thereby achieving the purpose of increasing amniotic fluid.
Amniotic fluid infusion can also be used to directly increase amniotic fluid volume. However, if it is found that the fetus is at risk of infection, or the fetus is in poor condition and is no longer suitable for living in the womb, it should be born immediately and taken care of properly.
Because BB has little amniotic fluid and is prone to hypoxia, you can take appropriate amounts of oxygen at home, go to the hospital regularly to monitor fetal heart rate, and count fetal movements every day. Do a good job of home monitoring and pay attention to the condition of the fetus at all times.
