When doing B-ultrasound examination, many doctors will help pregnant women measure the depth of amniotic fluid and the index of amniotic fluid to see if it is normal. This is also because there is not only a fetus but also a part of amniotic fluid in the uterus, which is also a very important factor for fetal development. If the depth and index of amniotic fluid are abnormal, it will affect the fetus. Is amniotic fluid index 140 mm normal at 32 weeks of gestation?
The amniotic fluid index of 140 mm was normal after 32 weeks of pregnancy. In fact, during the whole pregnancy, there is no problem that amniotic fluid index is between 9~24 cm. Whether it is more than this range or less, it may affect the fetus. Because amniotic fluid mainly plays a buffering role and can keep a suitable temperature in the uterus, it is still important.
Too much amniotic fluid has obvious influence on pregnant women, which may be premature placental contraction and weak contractions. In addition, because there is too much amniotic fluid, the range of fetal activities is still relatively large, and it is easy to have abnormal fetal position. In addition, too much amniotic fluid may cause the uterus to swell too much, resulting in premature birth.
However, the lack of amniotic fluid will mainly lead to fetal intrauterine dysplasia, and may even lead to deformity. Therefore, the normal index of amniotic fluid during pregnancy is very important for both pregnant women and fetuses.
