Why do pregnant women need to have pregnancy
ultrasound?
Ultrasound is the way that can record of
fetus in mother’s womb. As a result, mothers can see development of fetus and
also know many problems around babies and especially, they will know whether
babies can catch inborn defect or not early.

Why do we see fetus through ultrasound?
Image of ultrasound is formed by using
sound waves. Machine will send sound waves through body and after that it will
reflect again and change to an image that is showed on screen.
The way to make ultrasound: doctor will rub
gel that is used for ultrasound on pregnant women’s womb, after that the head
of ultrasound machine will be sweep pass by until fetus and placenta are
showed. Pregnant women and relatives can see fetus on screen.
Gel
will be rubbed on pregnant women’s belly to begin to have ultrasound.
3.
Which important moments should pregnant women
have ultrasound?
According to obstetricians, during
pregnancy, there are 3 moments that pregnant women are forced to have pregnancy
ultrasound.
From
the 12th to 14th weeks of pregnancy
This is the time that ultrasound doctor can
define age of fetus exactly. The more important thing of having pregnancy fetus
in this time is that doctor can measure bright space behind nape to predict
some unusual things of chromosome (these unusual things can be the reason that
cause Down disease, heart deformity, hernia of diaphragm).
If you have single or double fetus, this is
the time when doctors can give you the most exactly.
From
the 21th to 24th weeks of pregnancy
Most organs of fetus will be tested by
ultrasound doctor to ensure that fetus develops normally. Backbone, skull,
skull, heart, lungs, kidneys, arm and legs of fetus in the period can be seen.
Besides, doctors can detect most unusual
things about form of fetus such as harelip, cleft palate, deformity in internal
organs. This time is especially important because suspension of pregnancy can
be done before the 28th week.
From
the 30th to 32th weeks of pregnancy
Unusual things appear lately such as
unusual things in artery, heart, structure area of brain that will be detected
in this ultrasound time by doctors.
At this time, in ultrasound process,
doctors can check navel cord to recognize that whether it is good enough to
transport nutrients to nourish fetus or not, position of placenta, the state of
amniotic fluid (opaque or pure, many or little) will also be checked in the
ultrasound time.
4.
Which harmful things does ultrasound bring for
fetus?
There isn’t any research that affirms that
ultrasound has bad effect on fetus. However, pregnant women shouldn’t misuse
because there are the sensitive areas with ultrasound waves such as eyes or sex
gland. Doctors often humor mother’s psychology and they will snap these areas
most but this thing isn’t done because scientific purpose.
Ultrasound
doesn’t affect fetus; however, pregnant women shouldn’t misuse.
5.
2D ultrasound isn’t as good as 3D, 4D?
Many people think that 3D ultrasound is
clearer and it is easy to see. Therefore, it is better than 2D ultrasound. However,
according to experts, 3D ultrasound is only used the cases that detect defect
of fetus. It doesn’t give indexes about size, weight and age of fetus that are
as exact as 2D ultrasound.
6.
Ultrasound will detect fetus’s defect?
This thing is correct; however, it isn’t
correct in all cases because doctors cannot always detect fetus’s defect. In
some cases, when babies are born, doctors can detect those defects.
7.
What do you pay attention when you have
ultrasound?
Pregnant
women should drink a lot of water before having ultrasound.
Drinking a lot of water and enduring
urinating before having ultrasound are the things that women used to become
pregnant know clearly and women that become pregnant in the first time are like
a fish out of water. When you want to urinate, this is the best time for having
ultrasound because at this time, bladder will stretch and ultrasound will
become easier, doctor will see your baby more clearly.
