Normal value of lateral ventricle at 30 weeks of pregnancy

Is it possible to give birth at 30 weeks of pregnancy? During pregnancy, women should have a good life routine and diet structure, so that the baby can get better growth and development. Despite this, there will still be unexpected events. So, what should I do if the baby is premature? How to calculate the due date? What should I do if the baby hasn’t been born yet when the due date comes? How much is the standard value of the lateral ventricle at 30 weeks of pregnancy? Let’s take a look together.

Standard value of lateral ventricle at 30 weeks of pregnancy

An ultrasound examination was performed at 30 weeks of pregnancy, and the lateral ventricle was enlarged by 9.4mm, which is within the normal observation range. Come back for a follow-up visit two weeks later. If the standard value increases by more than ten mm, an MRI examination is recommended to see if there is any compression of the gyrus structure. If there is gyrus compression, further examination is needed to see if there are any abnormalities in other soft indicators to rule out congenital diseases of the fetus. If the value gradually decreases again, it means that the liquid inside has been absorbed.

Can I give birth at 30 weeks of pregnancy?

The definition of premature birth is that newborns born before 37 weeks are called premature babies. Most premature babies have low weight and body length less than 45cm (except babies of diabetic mothers). Premature babies have many potential risks and complications and require early evaluation by a specialist.

Even if premature babies survive, they often have defects in neurological and brain development. Therefore, preventing premature births is one of the key measures to reduce perinatal mortality and improve the quality of newborns. Therefore, a pregnant woman who gives birth at 34 weeks of pregnancy will already be giving birth to a premature baby.

Babies born before 37 weeks are considered premature.

Because technology is more prosperous nowadays and the nutrition consumed by pregnant women is generally better, the survival rate of premature babies has also been further improved. According to statistics, under modern scientific support, the correlation between the length of pregnancy and the survival rate is approximately: 17% at 23 weeks, 39% at 24 weeks, 50% at 25 weeks, 80% at 26 weeks, 90% at 27 weeks, 90% to 95% at 28 to 31 weeks, 95% at 32 to 33 weeks, and the survival rate at 34 weeks is almost the same as that of full-term babies.

1. Premature birth is the main cause of neonatal morbidity and mortality, and among the various causes of premature birth, the vast majority are maternal factors. Except for congenital reproductive malformations, most of them can be prevented through prenatal care.

2. Pregnancy check-ups should be given high priority, especially early and appropriate perinatal health care for these key subjects. For example, prevent and control pregnancy-induced hypertension syndrome, reduce the incidence of early fetal separation, seek early treatment after placenta previa is discovered, and correct anemia. Management of pregnant women with heart disease should be strengthened, basic knowledge of pre-pregnancy health care should be popularized, and preventive measures such as infection should be taken.

3. Use labor release to isolate premature babies and provide sufficient time to use hormone drugs to promote lung improvement before delivery.

Amniotic fluid depth standard at 30 weeks of pregnancy

The depth of amniotic fluid refers to the vertical depth of the amniotic fluid reservoir when a pregnant woman undergoes an ultrasound examination during pregnancy. It is a key indicator value used to determine the amount of amniotic fluid in a pregnant woman. The normal depth of amniotic fluid is 3-7cm. If it is ≥8cm, it indicates that there is too much amniotic fluid. When there is too much amniotic fluid, pregnant women are prone to complications of pregnancy-induced hypertension, placental abruption, abnormal fetal position, and increased incidence of premature birth. If it is ≤2cm, it indicates that there is too little amniotic fluid. Too little amniotic fluid can cause meconium deposition in the early stage of fetal delivery, and even premature birth or asphyxiation. Therefore, it is very important to control the depth of amniotic fluid for the baby's development.

The amniotic fluid depth of 31mm at 30 weeks of pregnancy is normal, and it is normal between 20-80mm. Less than 20mm is considered oligohydramnios, and more than 80mm is considered polyhydramnios. The sum of the amniotic fluid index based on the four positions is 113mm, which is also normal. Between 80-180 is also normal. Pay attention to regular prenatal checkups and pay attention to the baby's fetal movements.

If the depth of amniotic fluid is ≥8cm, it indicates that there is too much amniotic fluid. The effects of too much amniotic fluid on pregnant women mainly include placental abruption, uterine atony, postpartum hemorrhage, etc. Due to excessive amniotic fluid, the fetus has great mobility in the uterine cavity, which is easy to cause transverse position of the fetus; excessive expansion of the uterus and excessive pressure can easily lead to premature birth. If the amniotic fluid of the pregnant woman is discharged after rupture of the membrane, resulting in a decrease in the pressure in the uterine cavity, it may cause early embryo separation. In addition, the pregnant woman's uterus is large, and excessive expansion can easily cause uterine atony, and may also cause the risk of postpartum hemorrhage, all of which have a great impact on the pregnant woman and the fetus.

If the depth of amniotic fluid is ≤2cm, it indicates that there is too little amniotic fluid. The impact of too little amniotic fluid on the fetus is mainly to increase the perinatal mortality rate, which will cause fetal intrauterine developmental malformations and lack of oxygen. The impact on pregnant women is that it increases the probability of caesarean section.
