I found that I was pregnant according to X -ray and after taking medicine. Can the baby want it?

The question that makes pregnant mothers worry about finally answered!

Fans’ "faint wind" (pseudonym) asked: Dr. Fu Fu was pregnant for more than 20 days, took a film a few days ago, and took a medicine for toothache. Does it affect the child?

Will shooting X films be terators?

Everything is poisonous, as long as the dosage is sufficient.The American Radiation Society clearly states that the dosage of a single -diagnostic X -ray examination can not cause doses that can cause fetal damage at all.

Therefore, I hope this part of pregnant mothers should not worry too much.

Specifically, the X -line radio dose received by the fetus is lower than 50mgy, which will not have a healthy impact on the fetus.

It is only possible to have problems that can only occur from more than 100mgy, which can cause miscarriage, malformations, intellectual developmental disorders, etc. However, the diagnostic X -ray examination cannot reach the dose.

After receiving a single chest X-ray examination, the irradiation dose of the fetus in the abdomen was only 0.02-0.07mgy.

Moreover, the irradiation dose of the pregnant mother when shooting the chest is much lower than that of the positive X -rays of the pelvis.Compared with the torso, there are less adverse reactions caused by the exposure of the limbs.

Below is a common radioactive examination dose.Pregnant mothers can save on their mobile phones for easy reference when checking

It should be noted that the gestational week is different and the susceptibility to X -ray radiation is different.The following figure is the effect of contacting X -ray radiation dosage on the fetus at different gestational weeks.

For X-rays greater than 100mgy, there may be miscarriage at 3-4 weeks of pregnancy, because at this time, the fertilized eggs are very fragile; contact with 5-10 weeks may cause deformity, because this is the key stage of the development of various organ systems of the embryo;Contact from 11-17 weeks may lead to low IQ or even mental retardation.After 18 weeks of pregnancy, the diagnostic X -ray examination has no clear adverse effect on the fetus.

The data mainly comes from the research results of animal experiments, the research statistics of the survivors of the Japanese atomic bomb, and the crowd that needs to be treated with radio treatment due to medical reasons.

Will taking medicine affect the baby?

After the eggs are fertilized, the development of embryos and fetus is divided into three stages: early embryo, embryo period, and fetal stage.The sensitivity to drugs in different periods is also different.

1. In the stage of not sensitive (early embryo): within 2 weeks after fertilization, within 28 days after the last menstruation.

During this period, the impact of drugs on the embryo was "all or none": not the embryo died of death due to the impact of the death dose drug (all), or the fetus was not affected by the drug (none).

During this period, fetal malformations are generally not caused.

2. Sensitive period (embryo period): 3-8 weeks after fertilization, that is, 5-10 weeks of pregnancy.

This period is the period of organ differentiation. The embryo began to differentiate and develop. After being affected by harmful drugs, it can produce morphological abnormalities and appear deformity.

Specifically, if the nerve tissue is 15-25 days after fertilization, the eyes are 24-29 days, the heart is 21-40 days, the limbs are 24-36 days, the genitals are 26-62 days, and the drug is affected by the drug.

3. Low sensitivity period (fetal period): 9 weeks after fertilization, that is, 11 weeks of pregnancy-foot month.

This period is the stage of fetal growth, organs development, and perfect function, but the nervous system, reproductive organs, and teeth are still continuing to differentiate, especially the peak of the nervous system differentiation, development and proliferation.

During this period, the influence of drugs mainly involves fetal growth and organ function, such as limited fetal growth, low birth weight, abnormal functional behavior, premature birth, etc.

The fans of the "faint wind" are currently pregnant for more than 20 days. A few days ago, she took a film and took a medicine with toothache. If her pregnancy was more than 20 days of pregnancy, it was calculated from the last menstruation.It is 4 weeks of pregnancy and calculation from the time of the same room, which is 6 weeks of pregnancy.

Drugs that fall within 4 weeks of pregnancy are the role of the baby in the abdomen is all or nothing, nothing or abortion.

Similarly, a large number of clinical evidence in foreign countries shows that in the early pregnancy (note: here is the first 4 weeks of pregnancy, that is, from the first day of the last day of the last menstrual period, it will be accepted by X -rayThere are only two results of the baby’s influence: the first result is that the baby accepts all adverse effects and naturally abortion; the second result is that the baby is not affected by adversely, and naturally grows normally.

What about taking medicine within 6 weeks of pregnancy?

It is necessary to look at the instructions of the drug, because during this period is the period of differentiation of embryonic organs. The embryo began to differentiate and develop. After being affected by harmful drugs, it can produce abnormal morphological abnormalities.

For example, excessive body temperature in the early pregnancy is related to neural tube defects and other birth defects, so it is necessary to give antipyretic treatment.

Acetaminol is the preferred antipyretic drug for high fever during pregnancy, and it can also relieve headache and muscle pain. Other antipyretic drugs (such as aspirin, ibuprofen) may have adverse effects on pregnancy.

If this pregnant mother eats acetaminophen, it is safer, but if you eat aspirin or ibuprofen?Need a doctor to calculate the last time of medication for pregnant mothers.

If you fall in a sensitive period, then look at the nature of the drug, the half -life, reproductive and toxic target organs of the drug.

Finally, from the perspective of pharmacy, according to the above medication time, comprehensively evaluate the risk of pregnant mothers’ medication to the baby, and give advice to whether they can continue pregnancy.
