4 s 1150

Ultrasonography of pregnant women of an expert class is an expanded diagnostic research of the child. The technique of this diagnostics is developed by high-class foreign and domestic scientists.

Expert ultrasound during pregnancy is carried out by highly qualified specialists to confirm or refute most of the pathologies of the fetus and the expectant mother.

Features of the technique

The main advantage of expert ultrasound during pregnancy is that during the examination it becomes possible to detect even small pathological changes in the development of the fetus and placenta. At the time of ultrasound scanning, only high-precision stationary ultrasound devices are used. They will allow to determine the condition of the future child with great accuracy.

Three-dimensional and four-dimensional ultrasound methods are used without fail.

Main indications

A survey of this type is carried out on the initiative of a pregnant woman or as prescribed by a doctor. Experts recommend doing expert ultrasound in the following situations:

  • If the mother with the father of the future baby – blood relatives.
  • In case of missed abortion in the previous time.
  • If a woman has had an infectious disease in the first trimester of pregnancy or on the eve of conception.
  • Women over 35 years old.
  • If the parents have inherited diseases of different etiologies.
  • If the expectant mother in the period of carrying the fetus took illegal drugs.

What shows the expert class ultrasound on different dates

The following are the features of the procedure in different trimesters of pregnancy.

First trimester

Ultrasound in early pregnancy (week 5–8) is performed only to confirm pregnancy. In addition, the uzist checks the condition of the ovum and its location in the uterus.

Viability of the fetus can be determined by the heartbeat (180 beats in y) and its physical activity. In the first months of pregnancy, such a scan is a rather crucial moment, since it is from its results that the doctor can decide whether it is permissible to continue bearing the fetus.

First of all, the doctor pays special attention to the length of the embryo; it is determined by the coefficient of CTE (coccyx parietal size). Also, the doctor takes into account the circumference and head size, distance and diameter from the neck to the forehead.

TVP – the thickness of the collar space – helps to determine the chance of the development of various syndromes, including Down syndrome.

In addition to these indicators, the specialist looks at the following indicators:

  • total heart muscle size
  • the work of blood flow in the venous vessels
  • maxilla size
  • bladder volume
  • absence or presence of a new partition
  • heart rate in y
  • the presence of the so-called umbilical arteries
  • the presence of multiple pregnancy.

The timely implementation of an expert ultrasound provides all the chances of detecting the following serious fetal diseases in time:

  • heart defects
  • patau syndrome
  • de Lange syndrome
  • Down syndrome
  • Smith-Opitza pathology
  • omphalocele (umbilical hernia)
  • Edwards syndrome.

Second trimester

In the second trimester, expert ultrasound is usually scheduled for the twentieth week. At this time the doctor can more accurately determine the position of the child, weight, height, condition of the placenta.

The doctor visually examines every inch of the body of the fetus, and also assesses the following indicators:

  • face asymmetry
  • kidney condition
  • intestine, brain
  • cardiovascular system
  • markers chromosomal abnormalities
  • spine
  • stomach
  • limbs of a child.

Third trimester

Starting from the sixteenth week of pregnancy, the exact determination of the fetus of a baby is possible. The third scan is performed while being in the third trimester of pregnancy (32–34 weeks). Deviations of any kind on such a period are extremely rare.

If ultrasound examination in the second trimester did not reveal abnormalities, then the third time ultrasound examination is intended only to confirm the normal performance of the fetus and mother.

In the third trimester, doctors look at the following important indicators:

  • size of the unborn child (must meet the deadline)
  • position of the baby in the womb
  • placenta by structural parameters.

How to prepare

Five days before the ultrasound it is necessary to exclude the use of food products that can form increased gas formation (bakery products based on yeast, cabbage, any fruit and dairy products, beans). It is imperative that three days before the test, you need to start eating food enzymes while eating three times a day (but only as directed by the doctor).

The day before the intended examination, make an enema. If possible, ask your doctor to prescribe an ultrasound scan in the morning.

This will provide an opportunity to prepare well, and the decoding will be correct. On the eve try not to eat too dense food and drink more water.
