What is couplant?
During the ultrasound examination, the doctor will apply a layer of transparent viscous liquid on the skin. This liquid is clinically called ultrasonic coupling agent, which is mainly composed of water-based polymer gel. It is non-toxic and non-toxic. The color is also tasteless. Since B-ultrasound is conducted by ultrasound, when the B-ultrasound probe is in contact with the skin, it will not be able to observe the substantial organs because of the contact with the air. At this time, the application of coupling agent can fill the tiny distance between the probe and the skin and eliminate the skin and the probe. The air in between allows ultrasound to enter the body directly, revealing organ problems in detail.
And applying couplant can reduce the friction between the probe and the skin. Most pregnant women need to do B-ultrasound, but if the skin is relatively dry, the B-ultrasound probe will slide on the skin because it feels not fit enough, and pregnant women will Feeling unwell will also affect the test results.
Will the coupling agent affect the fetus?
Although ultrasound has no effect on the fetus, many pregnant women are worried that the coupling agent used will harm the fetus, but in fact, the coupling agent used clinically is colorless and non-toxic, and will not cause negative effects on the body, nor will it cause harm to the fetus. The fetus brings harm. Even if the coupling agent remaining on the skin is not removed after the examination, it will not cause any influence or side effects.
What should pregnant women pay attention to when doing B-ultrasound?
1. Relax yourself
Pregnant women should not be too nervous when doing B overtime. Relaxation can make the fetus emotionally stable and avoid the inability to get accurate results due to resistance during the examination.
2. Satisfaction
Because some examinations require an empty stomach, most pregnant women think that they also need to have an empty stomach for B-ultrasound, but it is not necessary. They even have to eat and fill their stomachs before the examination, so that the fetus can absorb energy and cooperate with the examination.
Warm reminder, B-ultrasound during pregnancy is an indispensable examination item. It can help pregnant women understand the development of the fetus in the uterine cavity and whether it is suitable for normal delivery. Therefore, some precautions for B-ultrasound should be clearly understood and have When in doubt, look for answers to avoid falling into misunderstandings, leading to blindness or even taking other measures to cause harm.
