At the moment, can IVF pregnant people do CT?

There may be radiation items in life abound.For example, the status of a mobile phone can be said to be unable to replace. You can go out without a bus card, no ID card, a bank card, no cash, because there is a mobile phone that can solve all problems.The office clan faces a computer every day for a whole day.

Most people’s consciousness stays in the fear of unknown.In the past, there were many introductions on the impact of radiation, such as the adverse effects of pregnant women and fetuses, such as causing tire stop, abortion, fetal malformations, gene mutations, and so on.

There is a safety factor in everything. In the natural context, the fetus will also accept a certain amount of radiation, about 1mgy.The influence of different degrees of radiation doses has different effects on the fetus.When the radiation dose is less than 0.05Gy (50mgy), there is currently no evidence to prove that the risk of fetal malformations, intellectual disorders, limited growth, or loss of pregnancy is increased.

At present, the CT examination plays an important role in evaluating the diagnosis and condition evaluation of COVID-2019.

Most patients in the IVF cycle are mostly on the way to conceive or have already conceived.At the moment of the epidemic, it is inevitable that the new coronal virus infection is excluded through the method of CT or nucleic acid detection.Those who are not conceived in the test tube cycle, do not panic if necessary CT examinations need to be performed. Single and short -term CT examinations have a small impact on later pregnancy.

Then let’s take a look at the amount of radiation that the fetus may receive if the test tube cycle has performed imaging examinations.The fetal radiation of the chest X -ray examination is usually 0.0005 ~ 0.01mgy, and the fetal radiation of the chest CT is 0.01 ~ 0.66mgy. In terms of ionizing radiation dose, the above two tests are far lower than the dose that may cause the fetal adverse effects.(50mgy).

Although the data is so, the radiation volume received by different gestational weeks is different on the subsequent impact of the fetus.1. Within 14 days of conception: This is the most sensitive period for embryos to ionize radiation. Considering the polyness of the extremely early embryonic cells, it is inferred that there are two possibilities: no damage survival or embryonic abortion at this time.2. 8 to 15 weeks of conception: If the fetus is radiated during this period, the risk of lag in mental development and small head deformity after birth.3. 16 ~ 25 weeks of conception: At this time, the sensitivity of the teratogenic sensitivity of the fetal nervous system and other organs decreased to ionizing radiation.4. 25 weeks of conception: At this time, the fetal teratogenic effect of ionizing radiation is relatively tolerated, and the possibility of major malformations and abnormal functional abnormalities is lower.

Seeing this is not completely relieved. After all, the impact of radiation on the long -term fetus can only be evaluated, but it cannot be concluded.Therefore, when pregnant women need to do a CT examination, the following suggestions are made:

Try to avoid radiation imaging examinations in the sensitive period of fetal development.; 4. If there is no clear history of epidemic diseases and those who have no clear clinical symptoms, avoid unnecessary CT examinations, those with conditions can choose nucleic acid examination.
