How often can you do an ultrasound
Ultrasound - is an ultrasound, with which you can diagnose pregnancy, identify abnormalities in the development, to establish the sex of the child. Many are interested in how often you can do ultrasound. Experts recommend an ultrasound in every trimester of pregnancy.
The first ultrasound is recommended for the period between the 9th and 11th weeks of pregnancy. The study can confirm the pregnancy, set the date and heart rate of the child. In the first trimester, an ectopic pregnancy or the risk of miscarriage can be seen on an ultrasound. You can find problems with the placenta, in the pelvis or in the uterus. Ultrasound examination can show abnormalities in the placenta (with intrauterine growth retardation, diabetes, Rh incompatibility), set the size of the neck area. If it is enlarged, it can be a symptom of a fetal defect. During this period, you can identify a multiple pregnancy and choose the tactics of its further management. The likelihood of genetic and medical problems in multiple babiespregnancy is 10 times more than with singleton. How often you can do ultrasound in multiple pregnancies, the doctor determines. In most cases, there is a need for more frequent research.
Second trimester ultrasound
When to do a second ultrasound, decides a specialist. As a rule, this is the period from the 16th to the 21st week. Ultrasound can determine the position of the fetus, its age, and sometimes gender. During this period, research is important to exclude malformations in development. Analyze the ratio of the period and the size of the fetus. If the doctor has any questions, the woman is sent to genetics for consultation for further detailed examination of the fetus.
Ultrasound in the third trimester
In the period from the 32nd to the 36th week, the third ultrasound scan is most often done. During these periods, it is possible to diagnose low-water or high-water flows, to ensure the normal development of internal organs, or to identify problems. Additionally, at this stage, the structure of the lungs is studied.
Ultrasound examination before childbirth
Do ultrasounds before childbirth to all women? When the pregnancy is normal, there is no need for additional research. When,when the last ultrasound study revealed the entanglement of a baby's umbilical cord or some other developmental disability, as well as with a large fruit, doctors recommend an additional ultrasound. On it, they clarify the condition of the child, his position, in order to determine whether the birth will take place naturally or there are indications for cesarean section.
Safety of the ultrasound procedure
For the first time, an ultrasound scan for pregnant women was done in 1958 in England. Since that time, not a single case of negative impact on the fetus or on the condition of the woman has been recorded. But in a private conversation, doctors note that ultrasound increases the tone of the uterus. How often can ultrasound be done to make it safe? With hypertonicity of the uterus or the threat of miscarriage, the procedure is carried out "under the cover" of antispasmodics. Therefore, if the question arises as to how often ultrasounds can be done, doctors recommend that you follow the measure. It is not necessary without special need to conduct numerous studies only with the aim of finding out the sex of the child.
