- Ultrasound during pregnancy - controls the development of the fetus
The first routine ultrasound in pregnancy
The first routine ultrasound during pregnancy conducted on 11-13 week. During the study of the fetus are determined: appropriate size and overall development of the fetus
Fetal development - week after week
pregnancy (gestational age determination by ultrasound is the most reliable), heart rate, various indicators of development of the skeletal system, the condition of venous blood flow, conducted inspection of the internal organs of the fetus (heart, stomach, bladder). This allows you to completely eliminate such gross fetal abnormalities as a lack of the brain, or the absence of deformation of limbs, spinal deformity, and so on.
It conducted a study of the future of the placenta, amniotic fluid, fetal membranes, the walls of the uterus (the presence of tumors), cervix, ovary (defined by the presence of the corpus luteum of pregnancy - cancer, which actively allocates progesterone
Progesterone - norm and pathology
during the first trimester of pregnancy).
Pi first ultrasound can install multiple pregnancy, and parents have more time to mentally tune in twins or triplets.
The second routine ultrasound in pregnancy
US in the middle of pregnancy by 21-24 week - one of the most important diagnostic procedures, which runs a pregnant woman. This enhanced ultrasound in pregnancy, it includes a comprehensive study of fetal membranes, amniotic fluid and the walls of the uterus, eliminates the majority of fetal malformations, as well as the risk of having children with certain chromosome and hereditary diseases, including Down syndrome. Identifies changes in the amniotic fluid, fibroids in the uterine wall. More reliable than at the first ultrasound, can detect multiple pregnancies.
Each organ of the fetus is examined in detail. Held measurement of the fetus. In particular, the measured width of the skull, and the length of the femur. If it turns out that the value of the body of the fetus does not correspond to his age, will be assigned additional ultrasound or other diagnostic tests. Determination of amniotic fluid in the uterus also allows you to identify the various problems in the development of pregnancy.
During the second held Doppler ultrasound, which detects violations of the placenta, umbilical cord, fetal insufficient blood supply. Ultrasound of the heart during pregnancy to determine the heart rate of the fetus. The study allows to verify the location of the placenta. If the placenta covers the cervix (placenta previa), this can lead to bleeding and a number of other problems in the later stages of pregnancy, so these women are taking on control and carry them further ultrasound.
This study also includes the definition of the child's sex. In some cases, this is particularly important, for example, if there is an increased likelihood of developing any of congenital disorders. Please inform your doctor if you do not want to know the baby's gender before birth.
Last ultrasound in pregnancy
Ultrasound at 32-34 weeks of pregnancy is carried out to exclude certain fetal malformations, intrauterine growth retardation, improper position or previa (location in the uterus) of the fetus.
Ultrasonography in late pregnancy may be necessary to ensure that normal if the baby develops (if you were previously aware of any problems), once again check the amount of amniotic fluid and determine whether to be a woman to carry out a caesarean section, or it can give birth naturally . If a woman in the third trimester vaginal bleeding started
Vaginal bleeding - if monthly return when they were not expecting
Using ultrasound can install its causes.
The results of ultrasound in pregnancy
Obstetrician-gynecologist very well how big the accuracy of ultrasound in pregnancy. For example, the calculator pregnancy ultrasound is the most accurate, it can be used to determine compliance with the size of the fetus midwifery date (the first day of the last menstrual period) pregnancy. Standards of ultrasound during pregnancy is calculated at the skeletal system of the fetus.
Routine ultrasound during pregnancy significantly reduced the number of children born with severe malformations. This study allows to identify and timely treat many pregnancy complications.
