Pregnant women must know the causes of fetal malformation douke

Notice: pregnant women cause fetal malformations in early pregnancy factor [Abstract], especially about 2 months of pregnancy the fetus is particularly susceptible to interference, possibly because of some negative effects appear deformity. What are the four factors that cause fetal malformations? How to avoid them? What should we do when we find a fetal malformation? An improper use of drugs, fetal malformation true story: the awesome power of drugs in 1964, Germany due to the occurrence of some pregnant women taking a pregnancy reaction called thalidomide as a sedative drug. Shortly after the birth of nearly 10000 cases of seal limb deformity, which led to the world’s attention to the teratogenic effects of drugs. People used to think that the placenta is a natural barrier to the fetus, and no drug can enter the fetus through the placenta. This has changed people’s understanding of drug teratogenicity. Any kind of drugs, including vitamins, a class of nutritional drugs, both on the side of its therapeutic effect, but also the side of its adverse reactions. On the one hand, it was related to the body condition of the drug users and the dosage and method. The study found that the drug can be transported to the fetus through the placenta in pregnant mothers, and even reached the same level of drug concentrations within the mother. 3 months before pregnancy, the most sensitive period for the use of drugs to treat the fetus is the period of pregnancy within 3 months. During this time, fetal organs began to develop, all kinds of protein and lipid synthesis activity, cell differentiation, and finally the formation of various organs and tissues. In the process of organ cell synthesis and differentiation by drug interference, it will cause fetal organ malformations. A single drug can cause multiple organ defects over a period of time, or a variety of drugs can cause a deformity. 3 months after the fetus, the basic development of the formation of organs, and then the use of drugs will not happen again. But we can not say that during pregnancy can not use, as long as the number of weeks of pregnancy to inform the doctor, after the doctor prescription and medication compliance, medication not only can be assured, but also can avoid the adverse effects of gestational hypertension, gestational diabetes and other complications of fetus. Two virus infections cause fetal malformations in early pregnancy to check if they are attacked by viruses in the early stages of pregnancy, some pregnant mother must check is done, including teratogenic virus check, most themonstrosity and virus, so when the pregnant pregnant mother must pay special attention to. The incidence of viral infection in pregnancy is higher than that of normal women, almost all of the virus can be transmitted to the fetus. Rubella virus, cytomegalovirus, varicella zoster virus and so on have a serious impact on the fetus. Pregnancy after infection can cause miscarriage, premature birth, stillbirth, intrauterine growth retardation and low birth weight infants, the survival of the fetus may lead to the change of congenital malformations and other systems. Abstract: in early pregnancy, especially in the 2 months of pregnancy, the fetus is particularly vulnerable to interference, and may even be due to some negative effects of deformity. What are the four factors that cause fetal malformations? How to avoid them? What should we do when we find a fetal malformation? The vast majority of fetal malformations are associated with the infection of these viruses, the most terrible is: pregnant mother infected with these viruses without symptoms.相关的主题文章:
