Is it possible to do chest X-rays to pregnant - what are the risks of the procedure?
Fluorography - a method of X-ray examination, which is used in the diagnosis of a variety of disorders.The X-rays penetrate the body's tissues, and provides images of internal structures.The question of whether it is possible to do chest X-rays for pregnant women, scientists have long been interested, and studies show that this procedure is generally not associated with a greater risk for the mother and fetus - if you do not carry it too often: ionizing radiation in high doses maybe dangerous.However, chest x-rays to pregnant never designate no urgent need.
When and how X-rays can affect the fetus?
In most cases, during fluoroscopy fetus is not directly exposed to X-rays.With this method often examined the chest, teeth, arms, legs - thus the risk to the fetus if it is any, is minimal.Fluorography can be potentially dangerous if the radiation is directed to the abdominal cavity, kidneys, pelvis, lower back, and so on.However, in these cases, the dose of ionizing radiation is usually very small, and if the procedure is carried out only once, it will likely not lead to any health problems in the child.
What can be dangerous effects of X-rays on the fetus?According to the available data to date, it can not lead to miscarriage Miscarriage - whether it can be insured? or congenital abnormalities that can cause violations of physical or mental development.
However, in some cases, especially when repeated exposure to ionizing radiation may increase the risk of cancers in children.
The effect of X-rays on the fetus may depend on the duration of pregnancy.It is believed that the first two weeks after conception Conception, ovarian cycle, fertilization and genetics baby embryo is very resistant to such effects.At that time, women usually do not yet know that are pregnant, but if during this period they do chest X-rays, the risk to the fetus is minimal.
between the eighth and fifteenth week of pregnancy is most sensitive to ionizing cure is the nervous system of the embryo.It was found that exposure to high doses of radiation radiation and its biological effects: gently infected! during this period may cause that IQ of the child will be reduced, but during fluoroscopy dose not high enough to cause an effect.
after the twentieth week of pregnancy, when major organs and systems in the body of the fetus is already formed, it becomes, in the opinion of many researchers, not more vulnerable to exposure to X-rays than his mother.After this period, fluorography, apparently does not have a fetus any harmful effects.
How can you reduce the risks?
How safe nor would fluorography, no precautions are unnecessary.
First of all, if a woman is to do chest X-rays, it must necessarily inform the doctor that she was pregnant.You should also tell the doctor if you only suspect you may be pregnant.In general, it is necessary to speak before any medical procedures, and before taking any medications.
If you have a small child, who will fluorography, do not keep it during the procedure.Have to make it child's father or someone from the family.This recommendation is also relevant for those who are planning to become pregnant in the near future.
During fluoroscopy cover the reproductive organs of a special lead apron, which should be in every medical facility, even though his patients do not always offer.
Finally, remember that doctors prescribe to pregnant fluorography only in cases when it is really necessary, and the abandonment of the procedure may be associated with greater risks than its implementation.
