Amniotic Fluid In Pregnant Women And Signs Of Identification
Pregnant women with amniotic fluid will reduce the uterus blood flow to the fetus. If this process is prolonged, it will lead to malnutrition consequences and more serious fetus stillborn in the womb or death at birth.
The role of amniotic fluid
Amniotic fluid plays a particularly important role in fetal development. Amniotic fluid is a nutrient medium in the amniotic fluid in pregnant women. Amniotic fluid occurs between 12-28 days after conception, is formed from three sources: fetus, amniotic fluid and the mother.
Amniotic fluid has the function of regenerating energy. Therefore, this substance can both provide nutrients to the fetus while helping the fetus avoid excessive compression due to uterine muscle contraction (when amniotic), affecting the blood supply to the fetus through the circuit. navel blood
Moreover, the amniotic fluid also contains fetal cells. Therefore, doctors can use the amniocentesis method to diagnose the genome of the fetus and determine the gestational age, by testing a number of other components in the amniotic fluid.
What is amniotic deficiency?
Lack of amniotic fluid means that the pregnant mother has too little amniotic fluid. The amount of amniotic fluid can be measured through methods such as assessment of amniotic fluid index (AFI), amniotic sac depth measurement ...
If AFI is less than 5cm, amniotic fluid volume is less than 500ml when the fetus is 32 - 36 weeks or 2-3cm deep, it is diagnosed as having amniotic fluid
About 8% of pregnant women have less amniotic fluid, of which 4% are deficient. For women who give birth late, the 42-week-old fetus is also susceptible to amniotic fluid deficiency because it is likely to halve by 42 weeks.
Amniotic deficiency is very dangerous which can cause premature birth and stillbirth
Amniotic deficiency is dangerous?
The severity of amniotic fluid deficiency depends on the time of amniotic fluid deficiency during pregnancy.
If the mother has an amniotic fluid in the first 3 months of pregnancy, the likelihood of miscarriage and stillbirth is very high. If the fetus is still alive, the development and function of the lung is also seriously affected.
A mother with amniotic fluid deficiency in the last 3 months of pregnancy can cause the fetus to be malnourished, with a high risk of premature birth due to fetal failure. In addition, the lack of amniotic fluid also causes the fetus to be inverted because there is not enough amniotic fluid for the fetus to rotate, making it difficult to give birth. However, the danger level of amniotic fluid in the last 3 months of pregnancy is still not too large, mothers just need to monitor health regularly, can transfer water to replenish amniotic fluid.
In addition, lack of amniotic fluid in late pregnancy easily causes the mother to have early amniotic rupture. Mothers should be monitored to avoid the risk of infection of the amniotic fluid and monitor the fetus's condition to intervene whether they should be born early or not.
Signs of amniotic fluid deficiency
Pregnant women can also recognize the situation themselves through some of the following symptoms: the waist circumference increases slowly while feeling the fetus activity more clearly than before, sometimes the fetus, pedal can causing significant pregnancy. This is due to the effect of lack of amniotic fluid, because when the fetus is active, it will act directly on the wall of the uterus, causing cramping pain.
At antenatal care, the figures show that the top of the uterus is protruding and the circumference is smaller than the standard for gestational age. At that time, your doctor will recommend an ultrasound to accurately assess the amount of amniotic fluid.
Amniotic deficiency can be diagnosed through ultrasound
Causes of amniotic deficiency
There are many causes of amniotic fluid deficiency, including the following:
Rupture of amniotic fluid, leaking amniotic fluid before labor: For some reason, the amniotic membrane is torn and the amniotic fluid escapes resulting in amniotic fluid deficiency. Lack of amniotic fluid due to rupture of amniotic fluid, leaking amniotic fluid is diagnosed through signs such as water, vaginal discharge much .
.. Patients need to see as soon as these manifestations to be diagnosed and treated promptly, avoiding influence. to the fetus.
Fetal chromosome abnormalities: Fetal growth retardation, fetal ultrasound imaging, or amniocentesis for chromosome testing.
Impaired uterine-vegetable function: This condition causes fetal growth retardation accompanied by amniotic fluid, amniotic deficiency.
Abnormalities of the fetal urinary system: If the fetus has abnormalities on both sides of the kidney, multiple kidney cysts, impaired renal function or obstruction of the ureter ..
. can cause amniotic deficiency. This condition can be detected through fetal ultrasound, venous blood testing in the umbilical cord.
Pregnant women with diseases such as high blood pressure, liver, kidney, pre-eclampsia will affect the function of placenta and the function of regenerating amniotic fluid. Therefore, when the mother suffers from these diseases, the chance of having amniotic fluid is very high.
In addition, maternal use of drugs such as ACE inhibitors, Prostaglandin synthesis inhibitors during pregnancy can also cause amniotic deficiency.
Methods of treatment of amniotic deficiency
Amniotic deficiency is usually diagnosed by ultrasound at regular prenatal care visits. Depending on the circumstances, the doctor may give intravenous amniotic fluid to maintain enough amniotic fluid needed for the developing fetus.
If amniotic fluid is deficient in the first 3 months, it is necessary to determine the cause from the mother or the embryo. From there, thing. . Dịch vụ: Thiết kế website, quảng cáo google, đăng ký website bộ công thương uy tín
