Many things are especially important during pregnancy, such as eating right, cutting out cigarettes and alcohol, and being careful about the prescription and over-the-counter drugs you take. Diagnostic x -rays and other medical radiation procedures of the abdominal area also deserve extra attention during pregnancy.
There is scientific disagreement about whether the small amounts of radiation used in diagnostic radiology can actually harm the unborn child, but it is known that the unborn child is very sensitive to the effects of things like radiation, certain drugs, excess alcohol, and infection. If radiation or other agents were to cause changes in these cells, there could be a slightly increased chance of birth defects or certain illnesses, such as leukemia, later in life.
It should be pointed out, however, that the majority of birth defects and childhood diseases occur even if the mother is not exposed to any known harmful agent during pregnancy. Scientists believe that heredity and random errors in the developmental process are responsible for most of these problems.
There are, however, rare situations in which a woman who is unaware of her pregnancy may receive a very large number of abdominal x -rays over a short period. This is important for many medical decisions, such as drug prescriptions and nuclear medicine procedures, as well as x -rays.
At UVA Radiology and Medical Imaging, we want to give you all the information you need to work with your doctor and make the best decision for you AND your baby. And it is important to keep in mind that the benefit of allowing your doctor to have a clear image of your medical condition most likely outweighs any potential risk to you or your baby.
In fact, the American College of Obstetricians and Gynecologists (COG) recommends that pregnant women maintain good oral health by keeping up with such routine dental procedures as X -rays, teeth cleaning, cavity-filling, and root canals. It's a still a good idea to use a leaded apron to protect your abdomen to minimize your baby's radiation exposure when you've been having other parts X-rayed.
In weeks 11 through 17, at the 5-10 rad dose, “Potential effects are scientifically uncertain and probably too subtle to be clinically detectable.” Though ACR notes that you can have IQ damage over the 10 rad mark, increasing with exposure.
(magnetic resonance imaging) or MRI during pregnancy poses no risk either to mom or baby. An MRI is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease.
While the study was not large enough to show a link to a risk for specific outcomes, it did show a slightly higher risk for stillbirth, neonatal death, skin diseases and inflammatory conditions among moms who had an MRI during pregnancy during which a contrast agent was used. In the second and third trimesters the fetus is growing and maturing but can still be affected by infections, drugs and possibly other factors.
In the third trimester the supine hypotension syndrome may result if the pregnant woman is laid flat. Elective dental care should be avoided in the last month of pregnancy, as it is uncomfortable for the patient.
Routine dental treatment of pregnant women under local anesthesia, for example extraction of teeth, is safe from the second trimester onwards, but unnecessary drugs should be avoided. When general anesthesia is unavoidable but there is a mishap to the fetus, the mother is likely to blame the anesthetist, even though this may be quite unjustifiable.
Despite such considerations, there is scanty evidence of teratogenic effects in humans from exposure to general anesthetic agents. The greater risk is late to pregnancy when general anesthesia may induce respiratory depression in the fetus.
Nevertheless, despite the existence of a few disastrous exceptions, notable thalidomide and some retinoids, very few drugs have been proven to be teratogenic for humans. Aspirin and other NSAIDs may cause closure of the ducts arterioles in the uterus, and fetal pulmonary hypertension as well as delaying or prolonging labor and therefore are contraindicated in the third trimester.
Aspirin, in addition, causes a platelet defect and may induce abortion and is best avoided throughout pregnancy. A small amount accumulates in the kidneys and also to a very much lesser extent, in brains, lung, liver and gastrointestinal tract.
