Benefits Of Fetal Doppler Ultrasound
Doppler ultrasound during pregnancy is an essential ultrasound and plays an important role in monitoring fetal development in the womb.
What is fetal Doppler ultrasound?
Doppler ultrasound, also known as color ultrasound, describes a technique that uses continuous waves to detect the directions and velocity of body flow. Ultrasonic uses high frequency waves that are not in nature, the machine will synthesize each received frequency signal and then display on the screen through different colors or spectrum, sometimes also audible sound.
In obstetrics, fetal Doppler ultrasound will measure the flow of blood vessels, measure fetal heart rate and other functions that traditional fetal ultrasound does not perform, while providing high-precision diagnostic values. .
Currently, Doppler ultrasound is the leading modern ultrasound technique widely used in health facilities and conducted during the last 3 months of pregnancy.
Does Doppler ultrasound affect the fetus?
When conducting Doppler ultrasound, pregnant women can feel secure because this type of ultrasound is safe, does not cause pain and does not affect the fetus. It is recommended not to abuse this ultrasound when both the mother and the baby are healthy
Classification of fetal Doppler ultrasound
There are 2 types of Doppler ultrasound:
Ultrasound uses special transducers with two crystals to play separate roles.
One crystal will emit continuous sound, according to a special mechanism and the wave will bounce back, the other crystal will be responsible for recovering this continuous wave.
Unlike continuous Doppler ultrasound, pulse Doppler uses only one crystal that will both perform sound emission and receive sound waves. Sound waves will travel along a series of pulses, along the direction of the scan probe.
The doctor will adjust the desired size and depth of the area to be analyzed.
Benefits of Doppler ultrasound
Doppler ultrasound during pregnancy will bring benefits such as:
Determine your baby's ability to absorb oxygen and essential nutrients by measuring blood flow in each part of the fetus's body (umbilical cord, brain and fetal heart)
Diagnose normal condition, healthy development of fetus by observing and assessing the condition of blood flow through arteries - veins
Early screening for birth defects and some fetal pathologies to provide the most appropriate treatment
The fetus is monitored for early detection of abnormal signs and prevents underweight
Determine the right time for your baby to be born
In addition, the doctor will designate the Doppler area and ultrasound unit depending on the condition of the pregnancy of the pregnant woman so it will bring different effects.
Uterine Doppler ultrasound
The role of the uterus arteries is to guide blood to the uterus of a pregnant woman to provide oxygen and nutrients to help the fetus grow.
So when the uterine Doppler ultrasound with a transvaginal or transvaginal probe will assist the doctor to check whether the placenta is getting enough blood
Note: This method only applies to pregnant women with normal uterus
Umbilical artery Doppler ultrasound
The fetus is supplied with oxygen and nutrients through the umbilical cord.
The umbilical artery Doppler ultrasound will help the doctor check the flow of blood from the placenta to the umbilical with such cases:
Fetal growth retardation
The fetus is affected by incompatible Rh antibodies
Multiple pregnancy (twins with the same egg), too high / low BMI, pregnant women with hypertension, diabetes ..
A mother with a history of low birth weight, miscarriage or a baby dies shortly after birth
At the same time, this ultrasound can identify fetuses with delayed onset growth (before 34 weeks).
Intravenous pulse Doppler
If an abnormal umbilical artery Doppler ultrasound is detected, your doctor will order you to continue the blood flow test using a venous pulse pulse or venous Doppler ultrasound.
Intravenous vessels provide oxygen and nutrition to the fetus' brain and heart.
Where is Doppler ultrasound?
With a team of highly qualified, experienced doctors, good and modern equipment systems and quality of professional services, Hopital Hospital will be a reliable address for pregnant mothers to go to prenatal checkups and Doppler ultrasound pregnancy.
Here, pregnant women will receive accurate diagnosis results and healthy pregnancy care advice for mothers and babies..
