summary

The fetus has been living in the water environment before delivery, and some newborn fetuses will have pleural effusion, which will make parents particularly worried. Let's talk about the causes of fetal hydrothorax.

What are the causes of fetal hydrothorax

First, the biparietal diameter of the fetus is too large, the normal range of 34 weeks should be about 85mm, the normal range of femur length and fetal heart rate, the normal thickness of placenta is 2-4cm, thin, the normal amniotic fluid index is 5-20cm, 35. 85CM belongs to polyhydramnios, which should be alert to fetal malformations, common neural tube malformations and digestive tract obstruction. In addition, the fetus also has pleural effusion. The fetus should be abnormal.

Second: polyhydramnios. The amount of amniotic fluid in normal pregnancy increases with the increase of gestational weeks, and gradually decreases in the last 2-4 weeks. The amount of amniotic fluid in full-term pregnancy is about 1000 ml. those whose amount of amniotic fluid exceeds 2000 ml in late pregnancy are called polyhydramnios. According to the increase speed of amniotic fluid in the onset time, they are divided into acute and chronic. Acute usually occurs at 16-24 weeks of gestation, which is fierce; chronic usually occurs in late pregnancy, which gradually increases in a few weeks.

Third: the common causes of fetal ascites are: chromosome problems of husband and wife; blood type problems of husband and wife; intrauterine infection; unknown reasons, such as environmental pollution. Various causes of fetal edema can be manifested as fetal subcutaneous edema, ascites, pleural effusion, etc., but pericardial effusion is often the earliest.

matters needing attention

There are many factors that cause fetal pleural effusion. It may be due to excessive amniotic fluid, or it may be due to the physical condition of both husband and wife. It is suggested that parents go to the hospital to have a detailed examination, so as not to delay the baby's illness.
