What is the probability of fetal malformation? Fetal malformation refers to the morphological defects of organs or body parts caused by structural or chromosomal abnormalities in uterus. What is the probability of fetal malformation? Fetal malformation accounts for about 3% of live births. There are about 5 million babies born with birth defects every year in the world, one every 5-6 minutes on average, and more than 85% of them occur in developing countries. The total number of children with congenital disabilities in China is as high as 800 ~ 654.38+200,000, accounting for 4% ~ 6% of the total population born in China. Severe deformity can lead to fetal and neonatal death or severe disability. Analysis of Seven Common Fetal Malformations during Pregnancy The most common fetal congenital defects are single malformation, mainly neural tube malformation, cleft lip, congenital heart disease and so on. , often a polygenic genetic disease. According to relevant reports, congenital malformation 10% ~ 25% is related to genetic factors, 10% ~ 20% to environmental factors, and 60% ~ 80% to genetic and environmental factors.
Generally speaking, the main causes of fetal malformation include: 1. Radiation injury: mainly occurs when exposed to radioactive substances in the first trimester.
2. Drug teratogenicity: taking teratogenic drugs in the first trimester.
3. Genetic factors: such as 2 1- trisomy syndrome and hemophilia.
4. Pathogenic biological infections: such as TORCH, Treponema pallidum, HIV infection, etc.
5. Mechanical stimulation: such as abdominal trauma, iatrogenic early pregnancy intervention examination, etc.
6. Bad habits after birth: taking drugs, smoking and drinking.
7. Other reasons. Prenatal screening should be carried out for high-risk pregnant women with a history of adverse environmental contact or abnormal family history, combined with laboratory examination and various instruments for diagnosis.
How to prevent fetal malformation 1? Pre-marital medical examination, some diseases found through examination, such as hepatitis B and sexually transmitted diseases. , will affect the health of future generations, resulting in fetal malformation, and can only be pregnant after being cured;
2. Be prepared before pregnancy, be prepared for planned pregnancy, and carry out some necessary tests, such as rubella virus testing. Rubella virus infection can lead to fetal congenital heart disease, congenital deafness, cataract and other malformations. Rubella virus infection can be prevented by vaccination.
3. Taking folic acid before pregnancy: Taking folic acid in the first three months of pregnancy can effectively prevent fetal neural tube defects.
4. High-risk pregnant women should have prenatal consultation.
5. Regular check-up after pregnancy: avoid contact with bad environment and drugs, quit smoking and drinking, do Down's screening, B-ultrasound examination, etc. Do prenatal diagnosis if necessary to find fetal malformation in time.
6. Consult a doctor when you need medication to avoid improper medication affecting the fetus.
