It is difficult to overestimate the diagnostic capabilities of ultrasound. It allows you to timely identify such dangerous threats as frozen and ectopic pregnancies. Later, ultrasound gives a picture of the development of the fetus, and it becomes possible to medically correct some of the detected abnormalities. You can determine the sex of the child, the approximate date of his birth. But there is a strong opinion: during pregnancy, ultrasound is harmful. Is it so?
It is believed that ultrasound negatively affects the development of the fetus in the womb. However, this is an emotional statement, not supported by arguments. But even in the seventies, a study was carried out on this topic, and even with old imperfect ultrasound machines, scientists did not find the harmful effect of ultrasound on the fetus.
But modern devices cannot be compared with the antediluvian devices of forty years ago. Ultrasound vibrates and heats tissues so that, in principle, it can damage living cells. However, the current equipment significantly reduces these phenomena, since the intensity and duration of exposure to a modern ultrasound machine is too small. Therefore, its harm to pregnant women is simply unlikely.
Of course, any therapeutic or diagnostic effect can be beneficial and harmful. Precise dosages are critical here. Do not get an ultrasound scan too often for the sake of curiosity, especially in the first trimester. Indeed, during this period, the embryo is most susceptible to electromagnetic oscillations, including ultrasonic waves.
Another thing is late terms, when many parents even take pictures of a five-six-month-old fetus as a keepsake. Any significant influence of ultrasound is practically impossible, since all organs and systems of the unborn child have already formed by this time.
In a word, fears that ultrasound examinations of pregnant women threaten with the risk of miscarriages, premature birth, increased infant mortality are devoid of arguments. At least, there is not yet a single scientific study in the world that would prove the existence of such a threat.
Equally unreasonable is the assumption that ultrasound “breaks” genetic structures, and such a “breakdown” of DNA may result in the birth of a mutant child. Laboratory studies of domestic scientists refuted this pseudo-theory - they did not observe any such metamorphoses even after half an hour of operation of the ultrasound machine.
It is sometimes argued that ultrasound has been introduced everywhere because it is needed for reporting purposes. Screening studies do provide very valuable information for both medical statisticians and medical scientists. What's wrong with that? Without this, progress is impossible either in the health care system or in medicine itself.
However, there is a significant practical reason in the judgments of the opponents of ultrasound, with which it is difficult to disagree. Not all doctors are able to flawlessly "read" the picture on the monitor of an ultrasound machine. Unfortunately, there are a lot of errors and blunders. Therefore, before going to the ultrasound office, it is advisable to clarify the qualifications of the diagnostician in advance.
