did you do ultrasound before amnio? and if the ultrasound was fine why did you go for amnio?

Question

My Dr asked me if I want to do amnio cuze, my blood test for down screen was 1in160, Iam 32 and firt baby, not down history in our families....I am thinking ot have ultrasound but I have heard that most ppl go for amnio at the end

Answer 1

An ultrasound scan is usually done before and during an amniocentesis to determine the best site to insert the needle, as well to ensure the needle is in the correct place to obtain enough amniotic fluid and does not injure the baby.

However i think the question you want to ask is that if it is necessary to do an amniocentesis if the baby's structures are normal on the scan and in the absence of family history.

First of all, most Down syndrome babies are born to women who do not have any family history, although the presence of a family history definitely put you at much increased risk.

When you have your serum screening test done for Down syndrome, your age has already been taken into account together with the blood test results. Therefore if your blood test shows an increased risk, you should consider having an amniocentesis to confirm the presence or absence of Down syndrome. However the decision is of course yours.

A normal fetus on ultrasound scan does not exclude a Down syndrome baby. In fact, examinations of the fetal structures on ultrasound scan, though good for detecting structural abnormalities, is rather unreliable in detecting Down syndrome. It typically misses about 50 - 60 % of Down syndrome fetuses, depending on the quality of the scan and how stringently your doctor wants to interpret the result of the scan.

I am 31 and pregnant, i was 29 with the last one, and both times i refused. The 1 in 160 is statistics for your age group. if you were 24 your numbers would be more favorable. My doc explained it to me. I just went for an ultra sound, i figured if there was anything wrong they would find it there. Would you abort if it was downs? I ask that, cause if you wouldnt, dont put yourself thru the amnio. Wait to see what God blesses you with. But if you feel your not ready to deal with a special needs, then do what you need to do. But you are 32, and first baby, what are your chances of having any more? I am not judging you, just throwing out a few things to think about.

Answer 3

Well, the doctor will always do an ultrasound prior to an amnio, to check where the placenta and baby are (you don't want to hit either of those with the needle.) I never had either with my children, but I had both babies when I was in my 20's.

FYI, I have many friends who have kids with Down's that had never had it in either family, so it might be worth checking out. It is something that you can be prepared for when the baby's born, plus, I believe there can be complications with the birth with a downs baby. But remember the chances are slim that your baby has downs syndrome. Good luck to you and your baby. Stay healthy!

before everything in accordance to the yank college of Obstetricians and Gynecologists ultrasounds are no longer area of habitual prenatal care. some years in the past they did an quite super learn and located that habitual ultrasounds do no longer develop any measurable effect (infant mortality, etc). despite if of direction they do advise one if there's a valid medical want. Amnio has by no ability been seen area of habitual care, it has severe adverse aspects and the only element it displays for is genetic disablities which includes Down's and spina bifida. With the exclusion of spina bifida not one of the syndromes it exams for are treatable for the period of being pregnant nor effect transport, the only "therapy" is abortion this is why they're in many cases preformed in the previous 20 weeks. In very severe circumstances sometimes they attempt surgical operation for spina bifida in utero and occaisionally they advise a c-area. They examine that the newborn is coming up the way they have for hundreds of years. They degree the fundal top, later they are in a position to palpate the newborn and choose its length (this is definitely extra precise in previous due being pregnant than ultrasound). They reveal screen the newborn's heart fee as nicely.

Answer 5

The ultrasound that follows a "positive" amnio is a different kind than the one used to verify the number of embryos and placental health. It's a higher resolution, allowing them to clearly see telltale markers of birth defects.
