Are the sonograms safe?

Sonograms are procedures that midwives use to identify the presence and development of the fetus. The sonogram is often referred to as ultrasound or Sonograph , especially after eight weeks of the fetus. Although the use of the procedure is widespread, there are some concerns about sonography safety in general and in particular its use in pregnancy screening.

One of the main concerns associated with the sonogram is the use of audio waves to transfer images that can be used to evaluate the unborn child. Certainly there is evidence that the use of sound waves can create heat that is harmful to human tissue. However, this type of activity requires the use of very high frequencies of sound waves. The devices used in sonography require only the use of low -frequency sound waves, and there is no evidence that they will cause fetal damage.

There are also concerns that although sonograms do not cause obvious tissue damage, they may have a negative impact on the proper brain development. SpecificallyThere is fear that sound waves cause some type of neurological damage that later manifests itself in life as a disability of learning. Because it is not uncommon for midwives to order an ultrasonic exam within sixteen to twenty -two weeks when brain development occurs, some wonder if invasive waves can disrupt this development.

To date, there is no evidence that sonograms cause any type of learning or brain defect. Testing carried out on human subjections was carried out by increasingly sophisticated methods and found no evidence of any impact on the function of the brain, positive or negative. However, testing with some animals has brought several situations where there is some apparent brain -cocoos that is associated with the use of ultrasounds. Due to these test results, research is researching possible bad effects of sonograms on human fruits.

While many people consider sonograms to be a test to determine the sex of the unborn child, the procedure is more commonly usedn to monitor progress of development or to identify the origin of some unusual pain or discomfort that the mother experiences, such as pain accompanied by bleeding. This means that some women do not have to undergo a sonogram until the last trimester of pregnancy, or maybe they will not undergo the procedure at all. Even most people with concern about tissue damage tend to admit that the fetus is usually sufficiently durable in the third trimester so that the low sound waves are not adversely affected in this type of testing.
