When Is Fetal Intervention Necessary When one talks about fetal intervention, that could mean a whole number of things. It could be something as simple as being hospitalized and monitoring the baby, to actually doing what I do, which is in-utero therapy where we manipulate the fetus and try to correct an internal problem. A woman really hopefully will never need to see me. That’s actually a good thing because if they need to see me then there’s usually some issue going on the fetus that needs some correction. Fetal intervention or fetal therapy is usually considered when the fetus itself has a very specific issue going on and where we need to change the neural environment or act upon the fetus in the womb in order to preserve the baby’s existence in the womb and give the best chance of survival after birth. No, ultrasound is not dangerous from a radiation perspective. What an ultrasound is, is actually really the transmission of low frequency sound waves that enable us to image the baby inside the mother’s womb so there really is no radiation exposure at all. There wasn’t a passing concern with the use of the frequency sound waves that it might transmit some heat and might that cause an issue for the baby. However, there have been many studies that have shown that frequent use of ultrasound is not damaging to the fetus.
