Sometimes there is no genetic defect in the fetus, but due to oligohydramnios, the amniotic membrane can adhere to the fetal surface, or the fetus is separated, and the fingers or limbs are separated. If there is too little amniotic fluid, the fetus is as dry and wrinkled as parchment. Amniotic fluid can still cause the fetus to stay in the uterus for a long time. It is easy to be oppressed and cause special musculoskeletal deformities, such as hand and foot deformities, degeneration, lasso deformities and upper limbs, which are usually opposite to lung development. When oligohydramnios occur, the height of pregnant woman and uterus is smaller than that of pregnant month, and the fetus lacks buffer. When the fetus moves, pregnant women will feel abdominal pain, and the fetus is confined to the end of the uterus, which is prone to abnormal fetal position. Primary uterine contraction is usually caused by primary uterine contraction or unequal contraction during delivery, and the uterine orifice is enlarged. Amniotic fluid is very small, sticky and yellow-green, and it is easy for the fetus to suffocate and lack oxygen after inhalation.
B-ultrasound diagnosis of hard liquid. B-ultrasound is superconducting, the amount of amniotic fluid is obviously reduced, and the interface between amniotic fluid and fetus is still unclear. Fetal limbs can significantly diagnose amniotic fluid, and then the depth of amniotic fluid is too small to be semi-quantitatively diagnosed. 28 years old? After 40 weeks of pregnancy, the maximum sheep pond was stable within 5.02.0 cm. If the maximum vertical depth (AFV) of amniotic fluid is too low, the amniotic fluid is too low ≤ 1cm. When amniotic fluid index (AFI) is used, AFI≤8cm is the critical value of hard fluid, and AFI≤5cm is diagnosed as hard fluid. How to diagnose in advance? For oligohydramnios, fetal malformation needs to terminate pregnancy as soon as possible; If the fetus is unfamiliar and mature, consider terminating the pregnancy. If the fetus is deformed, but the month is small, the influence of amniotic fluid can be reduced.
Because the fetus is relatively large for the fetus, especially within 26 weeks, if there is too much amniotic fluid, it will seriously affect the development of fetal lungs or lead to fetal disunion. Amniotic fluid can even lead to fetal hypoxia or even stillbirth. The fetus is wrapped in the tight bottom of the fetus, and the limb can't stretch, which may lead to the pressure melting of the limb. The symptoms of amniotic fluid mainly include: because amniotic fluid occupies a large volume in the uterus, if the amount of amniotic fluid is small and only the fetus is left, the volume of the uterus will become smaller, and the abdominal appearance and sputum (23:48) of pregnant women will also become smaller. Normal amniotic fluid volume is normal, fetal movement and fetal limb movement, some may feel fetal movement, but pregnant women may not feel it, because he may just beat amniotic fluid on amniotic fluid. However, if there is less amniotic fluid and the fetus moves slightly, it may directly act on the abdominal wall of pregnant women, and it will be more intense. Go to physical examination regularly and make B-ultrasound advice.
The causes of amniotic fluid include fetal factors, placental factors and maternal factors. So when you say amniotic fluid, you must first find the fetus itself. Some of them are urinary system malformations, because many amniotic fluids come from fetal urine, and some come from the secretion of placenta and fetal membranes. If it's the fetal urinary system, he has a problem, and his urinary system has a problem, and he can't be responsible, which may lead to this amniotic fluid. If the placenta is aging and secretes less, it also increases absorption, which will also lead to less amniotic fluid.
The fetus lacks oxygen and blood supply in the uterus, and cannot maintain the general circulation of its own body. The total circulation of the body is not enough, which must be maintained by reducing the balance between the bodies in this line, so the reduction of urination is also reduced, leading to the decline of amniotic fluid. Of course, there are also parents who have less water and are more expensive. The maternal teacher's blood pressure is low, and the circulating blood volume is reduced, which leads to the decrease of fetal circulation. Because the placental blood supply of the fetus comes from the mother, the mother can't eat, can't eat, or eat less, sweat more, or have shock symptoms, and the blood pressure is lower, or it will lead to less amniotic fluid in this fetus.
Amniotic fluid is not so little, you need to find a reason. If there is no hypoxia or deformity, the placenta function is also very good, but pregnant women may not have water at ordinary times, usually exercise more and sweat more, which may be made up by their mothers. In most cases, we can let pregnant women drink some water, and gradually drink 1000ml of water, and the daily settlement can reach 2000ml. Of course, replenishment is slow. If you go in, it's not the right time, and you may not be able to stand it. If the fetus of the fetus monitors the fetus and there is no obvious fetal hypoxia under normal circumstances, then we can provide some hydraulic treatment for pregnant women. You can also do some treatments to improve placental circulation. If it is caused by infection, anti-infection treatment can be carried out. Of course, some pregnant women have obvious ovine vectors and are less pregnant.
