Large exclusion of fetal abnormalities is an examination method that women need to actively adopt after a certain period of pregnancy to exclude fetal abnormalities. Modern people have very high requirements for the quality of reproduction, so many pregnant women will undergo prenatal screening. However, not all expectant mothers are aware of the precautions for major birth defects. This article will introduce the precautions to be taken when doing large-scale screening.
1. Advance reservation
The optimal time for selecting ultrasound for anomaly detection is around 18-24 weeks of pregnancy, when the fetal size is moderate and the ultrasound imaging is clear. At this stage, most abnormalities can be ruled out. Therefore, expectant mothers need to make an appointment at the hospital in advance to avoid missing the time. A gestational age that is too small or too large is not suitable for fetal malformation testing. However, the actual examination time for expectant mothers may vary.
2. No need to fast or hold urine
Abnormal screening does not require preparation for fasting or holding urine. As long as pregnant women go to a regular hospital for examination within the corresponding time, fetal abnormalities can be screened. Half an hour before undergoing prenatal ultrasound, expectant mothers can eat and drink some water to increase fetal movement.
3. Pay attention to your attire
The ultrasound examination focuses on the fetus in the uterus, so it is best for expectant mothers to wear separate upper and lower clothing before going for further examination to facilitate the examination.
4. Relax appropriately
If expectant mothers feel nervous before undergoing ultrasound, they should relax appropriately to relieve tension and prevent their nervousness from affecting the normal activities of the fetus and interfering with the normal test results.
This article provides a detailed introduction to the precautions for performing large-scale screening. If you are a pregnant mother and want to give birth to a healthier and smarter baby, it is best to actively carry out prenatal screening after a certain period of pregnancy. This way, the possibility of fetal abnormalities can be ruled out, and you can have peace of mind when giving birth.
