Normal and excessive amniotic fluid depth

With the development of medicine and the use of various examination instruments, regular prenatal checkups for pregnant women have gradually been promoted and popularized, because this is the only measure to prevent and early detect potential reproductive diseases. For prenatal checkups, one of the important indicators is the amniotic fluid index and amniotic fluid depth. Let us discuss the normal value of amniotic fluid depth and the problem of polyhydramnios. I hope pregnant women will pay attention to it during prenatal checkups.

Amniotic fluid depth is a medical term. It refers to the vertical depth of the largest amniotic fluid pool indicated by B-ultrasound examination. It is also an important indicator for judging the amount of amniotic fluid. The normal amniotic fluid depth (dvp) is 3-8cm. Before 28 weeks (7 months) of pregnancy, because there is more amniotic fluid and the fetus is smaller, the fetus has a larger range of movement in the uterine cavity and the fetal position is easy to change. After 32 weeks (8 months) of pregnancy, the fetus grows rapidly and the amniotic fluid decreases relatively.

As for polyhydramnios, the cause is still unclear, but 26% of cases of polyhydramnios are accompanied by congenital malformations of the fetus. Therefore, when polyhydramnios occurs, both the fetus and the mother must be considered together.

1. Fetal aspects: Possible causes include congenital malformations of the fetus (such as anencephaly, severe defects of the central nervous system, digestive system, gastrointestinal tract obstruction, etc.), fetal circulatory system disorders, blood stagnation, multiple births, etc.

2 Maternal factors: Possible causes include maternal metabolic diseases (such as gestational diabetes), abnormal obesity or syphilis, etc. In addition, if pregnant women have concurrent diseases of the heart, liver, kidneys, etc., they are also prone to polyhydramnios.

Therefore, once polyhydramnios is diagnosed, extensive examinations of the mother and fetus must be performed to determine the specific cause. The treatment approach should be determined based on the underlying cause. If you have gestational diabetes, your blood sugar should be controlled immediately; if you have congenital malformations, you should treat them according to the timing and severity. Excessive amniotic fluid is generally treated with conservative methods. For example: patients should eat more high-protein foods and stay in bed more often to avoid premature birth.

Therefore, prenatal check-ups are something that all expectant mothers and their families need to pay attention to and implement. The indicators, including the amniotic fluid depth discussed above, also need to be understood and recognized by everyone. If there are multiple symptoms, you must go to a professional hospital for diagnosis and treatment immediately, because this may be related to the early or late delivery, the maturity of the fetus, whether puncture is needed, etc., and all must be decided at the first time.
