How is he (she) there?
At this time the weight of your crumb reaches 1800 grams. The fruit in most cases has already turned head down. The legs are in abutment with the ribs of the mother. For this period the child has already established a regime of sleep and wakefulness. In a day 90% of the time he is in a state of sleep.
The fetus at the 32nd week of pregnancy is more plump pens and legs, smooth skin without wrinkles. Tightness of the uterus accompanies the stay in the embryo position, that is, with crossed limbs.
The development of the child is almost complete - the brain is completely formed, only the lungs continue to develop. Nervous reactions and reflexes are also formed. This level indicates that the child sees dreams and hears the voice of his mother. At this stage, the main task is good oxygen therapy of the fetus, since the lungs are not completely formed.
Calendar ultrasound: tasks and indicators
By this time, the weight and size of the fruit do not give you the opportunity to see it completely. Most likely, Mom can not even figure out what the monitor is showing. But with 3D ultrasound, all parts of the baby's body are clearly visible.
Ultrasound at this time should be passed to all pregnant women, because it plays an important role in predicting the outcome of pregnancy. Already the doctor, most likely, can tell or say, as will pass or take place labors. The ultrasound shows the placenta previa. The estimated growth of the fetus is 42 cm.
The decoding of ultrasound readings at this time is carried out using spetsnorm. The measurement parameters are called & bdquo; fetometry of the fetus & rdquo; .
So, what can be detected with the third planned ultrasound?
- The pathology of the placenta. The placenta should be in the bottom or on the wall of the uterus, above the internal pharynx about 5 cm. If the edge below is a low placenta, if it slightly covers the inner pharynx - partial placenta previa. When the zev is completely blocked, this pathology is called & bdquo; complete placenta previa & rdquo; . The possibility of independent delivery depends on the severity of the presentation of the placenta. In addition to localization, the doctor assesses her condition on ultrasound. There are 3 degrees of maturity of the placenta. At 32 weeks, the thickness of the placenta is quite a significant indicator, and it usually is just over two centimeters. When the degree of maturity of the placenta does not meet the term of pregnancy, there is a problem of feto-placental insufficiency.
- Pathology of the umbilical cord. It is the third ultrasound that makes it possible to identify the fetal cord with the umbilical cord. Often, there is no threat to the baby, if the accent does not violate the blood flow. Otherwise, this can be a dangerous phenomenon.
- Fetal pathology. Ultrasound may detect a discrepancy between height, weight, gestational age, developmental abnormalities and tumors. These deviations are observed only with 3D-ultrasound. If at the 32nd week of pregnancy you were told that a future child has a pelvic presentation, do not worry and get nervous before the time. Only 3% of babies remain in the position popkoy down to the birth, the rest have a lot of time to turn around as necessary - head down.
- Pathology of the cervix. At this time, the neck is closed tightly, has the shape of a cylinder. On ultrasound, you can consider the signs of the so-called maturation of the cervix: shortening and smoothing. This may indicate a threat of premature birth.
- Pathology of amniotic fluid. Their number decreases with time and at this stage is about 1.5 liters. Malnutrition or polyhydramnios too can show an ultrasound. The amount of amniotic fluid is estimated using the amniotic fluid index (IOL). The doctor measures the free zones in the uterus in 4 places, then summarizes them and divides them by 4. The norms can be searched in special tables if desired, but if there is a pathology, the doctor will necessarily inform the patient about it.
- Rumen pathology. It's about the scar on the uterus from caesarean section, because such an operation always leaves a mark on the wall of the woman's uterus. Therefore, in subsequent pregnancies, stretching and weakening of the postoperative scar are possible. Sometimes even this is fraught with a threat of rupture of the uterus. The ultrasound gives an opportunity to accurately assess the thickness and condition of the scar. Results of ultrasound, as in previous studies, must be recorded in a special protocol. Based on the information received, the obstetrician-gynecologist who observes you will make a plan for the course of the last months of pregnancy, sometimes even childbirth. Probably, the recommendation of carrying out CTG of a fetus follows.
It should be recalled that all instructions and prescriptions of the doctor must be carried out strictly on time and without fail. This is the guarantee of normal delivery and the birth of a healthy child.
