Explain to me ultrasounds, please.  

post #1 of 10
Thread Starter 
I see that several of you are anti-ultrasounds and I don't understand why. Are they not sound waves, not radiation? I will be getting them every 2 weeks for the first little while becasue of the difficulty I had getting pregnant. I have trouble thinking that my fertility clinic would have me get so many if they were harmful, especially considering everything I went through to get pregnant, and all of the medications I am on now to stay pregnant.
I'm so confused.
thanks,

If it makes you feel any better, I had to have several with my first two babies, and they are fine/normal.

I had ultrasounds with both baby #1 and 2, and they also came out fine. I think alot of the concern is that there hasn't been research on long term effects. Otherwise I have decided not to do a ultrasound this time around because the only reason I would want one would be to find out the sex and I really don't want to know this time around. I am totally not against medically necessary ultrasounds, or peace of mind ultrasounds, I am just trying to build trust between myself and my body again and I feel like this is the path that I need to go down to accomplish that if that makes sense?

After quickly reading the 2 articles I didn't see anything about ultrasounds being harmful. The only concern I could see is that they can mis interpreted and cause a misdiagonoses which may lead to a more invasive test. I was under the impression that people didn't want them because they were harmful.

Ultrasound has been used in pregnancy since 1956. There are plenty of research studies that indicate delayed speech as one side effect. It can heat amniotic fluid through a process known as cavitation, and this can precipitate a miscarriage or birth defects. There are plenty of studies done at Oxford University for one by Dr. Alice Stewart that says that ultrasound use in pregnancy should not be considered routine.

As for "radiation", ultrasound is known in physics as "non-ioninzing radiation"; it is sound that "radiates" through solid materials (skin) and liquid (amniotic fluid)and bounces off a solid to give a reading or location. It was and is used to find submarines.

When something is found to replace ultrasound, we will all know the dangerous side effects. Meanwhile, remember ultrasound replace xray pelvimetry in pregnancy because prenatal xrays increase cancer rates.

I see where people are against them but I am not. I am a little miffed that I will get one only if I am lucky. I had them every vist from week nine with e and e is beyond the picture of health. I think for a few moments one or twice a month is fine. Now if you are hooked up to one all day everyday your whole pregnacy I can see where THAT would be troublesome but like all thinks good and bad, moderation is key. Drinking all day everyday is VERY bad for you but a glass of wine a day is okay. I also think that the stress of wandering how you lil bean is is MUCH worse than the occasional U/S. It is your call, do what feels right to you. s

I wouldn't say I'm "against" ultrasound, as it does have valid medical uses during pregnancy. I do think that it is overused and shouldn't be considered routine. There are potential risks with it's use and it seems that most of the information gained from ultrasound is very open to interpretation. In other words, the results are not definite. It is nice to have the peace of mind that having a "good" ultrasound can provide, but the other side of the coin is that mothers worry about negative, often incorrect, information that is given through ultrasound. I can't remember the number of threads here that I have read in which a mother is in tears because her doctor has informed her that her baby has or might have certain issues. A lot of the time, the baby turns out to be perfectly fine.

It has been a long time since I researched this, but apparently Doppler ultrasound is stronger and potentially more harmful than the other type of ultrasound. For that reason, I also prefer to avoid Doppler use. For the most part, it seems that Doppler use in pregnancy, as opposed to its use in birth, is just to check that baby is alive! Most of the time, this is not necessary. Once the mother can feel movement, I personally don't know of any reason to routinely use Doppler. If there are concerns, of course that is different, but I imagine that regular ultrasound or continuous monitoring would be more helpful in such a case anyway.

~~~

Despite my feelings about ultrasound, I've had one in each of my pregnancies so far. With my first, I had one ultrasound because of vaginal bleeding (thank G-d, everything was fine). I also heard the heartbeat with the hand-held Doppler maybe 4 times and intermittently in labor.

With my second pregnancy, I really hoped to avoid ultrasound. Again, I had vaginal bleeding, but I waited it out until I felt sure that something was wrong (the bleeding was getting heavier and I was cramping, etc.). I knew there was nothing that could be done to prevent a first trimester miscarriage, so when I finally had the ultrasound I was mostly confirming what I already knew, even though I hoped for the best. It turned out I was right (no heartbeat, baby small for dates), and I miscarried that night after having the ultrasound. I ended up having another ultrasound to confirm that the "products of conception" had all been passed.

With my third pregnancy, I had hyperemesis and needed to go to the emergency room for IV rehydration. They didn't even tell me they were ordering an ultrasound for me; they just wheeled me to the ultrasound room! Then they told me that they needed to check if I was having twins or a molar pregnancy, because apparently hyperemesis is more common in those cases. When I heard "twins", I couldn't help but consent to the ultrasound! I was really hoping to see two babies. I didn't have any Doppler with that pregnancy. I had a UC, so I didn't have any during the birth, either.

I've been musing on this today and the cavitation thing really pushes me to consider no U/S for us without some serious indication. An U/S does not make a baby stick or make a baby healthy, and it has risks, not only the actual risk of being exposed to the ultrasound but the risks of starting on a path of enquiry that logically ends in CVS or amnio, which if I don't think I'd do is not worth starting on.

I'm not against them either...I think those who get them for fun or more pictures is a bit much (I've known ppl to do this).

However a later u/s probably would've saved my baby's life and saves alot of babies lives everyday (in life threatening issues that are already addressed before baby is born).

I'm glad we have it. May be a little overused in some cases, but I do know that my next pregnancy will be high risk (had a stillbirth) and I will have to be monitor one, yes, by u/s frequently in my 2nd and 3rd trimester.
