Elevated Body Temperature Fever is a common teratogenic factor. The higher the fever and the longer it lasts, the more teratogenic it is. Therefore, it is important to pay attention to warmth and cold during early pregnancy, avoid contact with febrile patients, and avoid febrile illnesses as much as possible by minimizing visits to public places with unclean air and overcrowding. The teratogenicity of fever often exceeds the source of the disease. For example, bacterial infections, bacteria often do not cause teratogenicity and fever causes teratogenicity. Once you have a fever, you should go to the hospital immediately for early cooling and treatment. Other problems that cause an increase in body temperature, such as high-temperature work, sauna, hot tub baths, etc. are not suitable for early pregnant women (pregnant women food) women, should be avoided in early pregnancy. Tobacco and alcohol Smoking or passive smoking can affect fetal development. Although there are no obvious cases of fetal malformations, it is very common to see low birth weight babies and children with developmental delays. If tobacco and alcohol continue to stimulate until childhood, it will also affect the body in adulthood. Therefore, pregnant women themselves do not smoke, but also to avoid the environment contaminated by smoke. Everyone should pay attention to public morality, do not smoke in public places, so as not to harm others and future generations. Alcohol is a recognized teratogen. Sperm quality of alcoholic husbands may be affected. Pregnant women who drink alcohol have a very high rate of fetal malformations, and children with alcohol syndrome have multiple malformations, developmental delays and mental retardation. Therefore, alcohol should be absolutely avoided during pregnancy, especially during early pregnancy. If the menstrual period, although not yet diagnosed pregnancy, also avoid alcohol observation. Abuse of drugs During pregnancy, illness must be treated, but not abuse of drugs, because some drugs have adverse effects on fetal development. Therefore, if you are sick, you should ask your doctor to treat you, no matter what kind of disease you have, you should explain to your doctor that you are pregnant, so that the doctor can pay attention to the choice of drugs in the treatment. Blindly preserving the fetus in case of miscarriage Miscarriage is sometimes a sign of poor development of the fetus. Therefore, to preserve the fetus, we should pay attention to find the cause of miscarriage. If the mother’s factor is the main factor, common trauma, uterine fibroids or uterine malformation, a history of endocrine disorders and other factors, we can actively preserve the fetus. If fetal factors are considered, the fetus should not be actively preserved in order to avoid preserving the abnormal child. From time to time, when abortion is cured under unknown reasons, the development of the fetus should still be carefully observed so that abnormalities can be detected in time. Exposure to toxic and harmful substances to the fetus Pregnant women should pay attention to avoiding exposure to toxic and harmful substances at work or in life. For example, radiation, pesticides, lead, mercury, cadmium and other substances. When the nature of occupational exposure is not known, consult with your doctor so that you can control the exposure time, dosage and other conditions, and take precautions to avoid harming the fetus. How to prevent fetal malformations To take the premarital medical examination seriously, through the examination of some of the diseases found, such as hepatitis B, sexually transmitted diseases, etc., these diseases will affect the health of the offspring, triggering fetal malformations, only after the cure to get pregnant; do a good job of pre-pregnancy preparations, do not get pregnant blindly, to do a prepared, planned pregnancy, some of the necessary tests, such as rubella virus test. Rubella virus infection can lead to congenital heart disease and congenital deafness in the fetus, which can be prevented by rubella vaccination; take “Silien” folic acid tablets in the first trimester of pregnancy to prevent neural tube deformities in the fetus. Avoid pregnancy in spring and winter, as there are more viruses in spring and winter, and the incidence of fetal malformations is significantly higher in spring and winter than in summer and fall. Establish a perinatal health care card immediately after pregnancy and have regular checkups. Down’s syndrome screening can be done at 14-20 weeks, and ultrasound test can be done before 28 weeks, etc. All these tests can find out whether there is any malformation of the fetus at the early stage of pregnancy. Prevent infectious diseases of the reproductive tract. Reproductive tract infectious diseases are mainly caused by unclean sex, so it is necessary to regulate sexual behavior, diagnosed should be treated in a timely manner, pregnant women who find themselves with abnormal secretions should also consult a doctor in a timely manner, can not refuse to use medication because of pregnancy, or even avoid medical treatment. The five bad habits of late pregnancy easily lead to fetal malformation.
