Our today topic is pregnancy ultrasound.We will talk about pregnancy ultrasound.Do you agree that ultrasound in pregnancy is save?For both parents, ultrasound is a unique moment: it’s their chance to see their baby for the very first time.An ultrasound is usually suggested between 18 th and 20 th week of pregnancy. This examination makes it possible to:
know the age of the pregnancy (especially if your menstrual cycle is irregular or if you do not remember the date of your last period) and thus avoid causing the work unnecessarily;
know the size of your baby according to his age;
see most of your baby’s limbs and organs (heart, liver, kidneys, stomach, bladder, brain, etc.) to detect abnormalities and intervene as needed;
find out if there is more than one baby
know how is your placenta placed .
An ultrasound performed between the 11 th and 14 th week of pregnancy you may also be proposed to measure nuchal translucency (the space between the neck skin and the spine of the fetus) and attempt to detect certain abnormalities. If the result is higher than normal, this could mean that the baby is at risk of trisomy 21, other chromosomal abnormalities or heart defects. For more precise results, however, it is necessary to add to this blood samples. Other tests can be done by ultrasound, but these are less common.
Do you want to know sex?
Ultrasound is also the time when you normally can tell, despite a small risk of error, whether you are waiting for a boy or a girl. However, because of the position of the fetus, it is sometimes impossible to know the sex of the baby. If you want the sex of your child to remain a surprise until the time of delivery, tell the technician and the doctor to avoid revealing the secret.
Is ultrasound safe?
During ultrasound, low-energy ultrasound is directed to the fetus. In humans, no long-term negative effects, both physical and cognitive, have been associated with ultrasound. Because of the benefits of ultrasound, experts agree that this technique is safe under the following conditions:
It is used only when it is medically necessary. For example, a routine ultrasound is recommended between the 18 th and 20 th week of pregnancy to establish the age of the fetus and detect potential abnormalities;
The energy level of the ultrasound is set to a minimum;
The number and duration of ultrasound sessions are limited.
The Canadian Association of Radiologists and the Society of Obstetricians and Gynecologists of Canada, however, warn parents against the use of ultrasound for the sole purpose of knowing the sex of the baby or to obtain pictures or videos of the fetus. Indeed, these practices unnecessarily increase the baby’s exposure to ultrasound. Some studies, conducted in both humans and animals, have indicated that there is a theoretical risk that this energy has effects on the development of the fetus, reads the statement of common principles of the two groups .
