Do you need to hold your urine during pregnancy ultrasound?

Many people think that B-ultrasound will have radiation which is not good for the baby, so they don't do it. In fact, this is incorrect. B-ultrasound will have an impact on the fetus but it is very small. Generally speaking, whether to do a B-ultrasound depends on the situation. Drink more water two hours before the B-ultrasound. Holding urine will make the B-ultrasound clearer. But don't do the B-ultrasound on an empty stomach, as the baby will not cooperate.

【Pay attention to the best time to do B-ultrasound during pregnancy】

The best time for B-ultrasound examination is generally after 5-6 months of pregnancy. The older the fetus is, the smaller the impact of ultrasound on the fetus. If an ultrasound is done too early, the gestational sac will be too small to be easily observed, and it will also cause vibrations to the fragile, newly formed embryo, which is not conducive to embryonic development.

【Pay attention to the number of B-ultrasounds during pregnancy】

How many times ultrasounds are needed during pregnancy depends on the specific situation. Under normal circumstances, it is best for expectant mothers to have 3 ultrasounds during pregnancy, and no more than 5 times.

The first B-ultrasound examination should be done between 12 and 16 weeks of pregnancy: an ultrasound examination at this time can determine whether the pregnancy is single or multiple, and can measure the size of the fetus and its development.

The second B-ultrasound examination should be performed between 20 and 25 weeks of pregnancy: The B-ultrasound examination in mid-pregnancy can help expectant mothers understand the growth and development of the fetus, and can also have a further understanding of the fetal position and the amount of amniotic fluid. It can also detect fetal malformations at an early stage, such as fetal limb deformities, cleft lip and palate deformities, etc.

The third B-ultrasound examination should be done between 37 and 40 weeks of pregnancy: The B-ultrasound at this stage can help expectant mothers observe the fetal position, fetal size, degree of placental maturity, whether the umbilical cord is wrapped around the neck, etc., conduct a final assessment before delivery, and make various preparations before delivery, so this B-ultrasound is very important.

[Pregnant mothers should know: Precautions for B-ultrasound during pregnancy]

1. In the early stages of pregnancy, an ultrasound requires a certain amount of urine to accumulate in the bladder in order to see clearly, so you need to hold your urine in advance. After 3 months of pregnancy, the baby has grown bigger and you don’t have to hold your urine anymore, you can do it whenever you want.

2. Do not do an ultrasound when you are hungry, especially in the middle and late stages of pregnancy. If you are hungry, the baby will not cooperate, and some data may not be clear or can not be measured, or the measured data may be inaccurate.

3. Try to relax as much as possible during the examination and cooperate with the doctor. If you are too nervous during the examination, it may affect the effectiveness of the examination.

4. Do not eat foods that easily produce gas, such as milk, sweet potatoes, etc., before having an ultrasound, because this will hinder the penetration of ultrasound and cause unclear imaging of the examined organs.

5. Before doing the B-ultrasound, touch your belly more and tell your baby to cooperate well, and your baby will cooperate with you.
