ULTRASOUND EXAM

The exams in this video were conducted by an obstetrician. If your exam is conducted by a sonographer, you'll discuss results with your doctor afterward.

ULTRASOUND | 27 WEEKS PREGNANT | KATIE

Dr. Lizellen La Follette: Okay, Katie, I'm putting some goop on your belly again. Special pattern of frosting. There we go.

Okay, so typically when I do an ultrasound I want four measurements: I want to do the baby's head, the baby's belly, the baby's thigh – and that gives me a weight – where the placenta is, and the amount of fluid around the baby.

I'm going to measure the baby's head. There's cute little fingers here already, two footsies, little toes. Do you see the little toes? And this is ear – so inside of the skull bone to the outside of the skull bone – so that's the inner ear inner ear. And this measures 26 weeks and 2, and that's exactly right for your dates, right?

Katie: Yeah.

Dr. Follette: So each time we do a measurement we will get dates. They won't always be this close, but for this kid and you, of course, your kid's perfect.

So what I'm going to do now is I'm going to go from the front of the head – this is where the eyes are, okay? So I come over here. So now I have another measurement, which is, so I have two measurements, and they're a little bit off. See, that comes out at 21? But they're close.

Now, look at the cute little face. See the little eyes, right? See the little face there?

Katie: Yep, yep.

Dr. Follette: There's my belly measurement. Spine is here. I have a circle of the belly, and as I get myself close to the edge, that's going to give me a nice belly measurement. Look where we are: 25, 25 and 5. Does that make sense?

All of these measurements show that this baby is completely, appropriately grown. We want to have dates that are within two weeks of each other from your due date, and you are within days of each other on all of those measurements.

So now, normally for you, our next scan would be at 36 weeks.

ULTRASOUND | 36 WEEKS PREGNANT | MICHELLE

Dr. Lizellen La Follette: Michelle is over 35, so we are going to do her 36-week scan. And then every week from now on she comes in for a non-stress test and a fluid check until she has the baby.

So now, just the first thing we are looking at when we put all of this goop on her belly, right? So this is head, so I'm going to first get you the lay of the land, and then I'll take some measurements. The head is here. This is a cute little fist like this, okay? Fair enough, you can see it nicely, can't you? So here is the placenta. Look at the little fingers over here. There's plenty of fluid around this baby already. Now look at the size of that kid. We can hardly get the whole baby in the screen.

See how the baby's back is up? That means the baby's going to be head down the way I want it to be. Here's the femur. So now I am going to do some measurements related to the baby's size. So I'm going to measure basically end to end of the bone, and it'll give me a date, right? So this says 34 weeks and 3. Now we know you're 36 weeks, right? It doesn't matter if the dates are a little different, it just means we are within two standard deviations of the norm.

See this circle? That's the baby's abdominal circumference.

Michelle: Gotcha. So it's kind of looking down?

Dr. La Follette: It is almost as though we are doing a cross-section.

Michelle: Okay, yeah.

Dr. Lizellen La Follette: That's a great question. So then we get the abdominal circumference, also known as the AC. And look at the dates on here. So this means the kid's perfect on the growth.

So then I go down here and I get the baby's head. So I'm trying to get the cross-section of the head to get to the level of the thalami, which is a special internal brain structure, kind of ear-to-ear measurement. So look at that: 36 and 6. And we are going across again. And then I get to about there. That looks about right, doesn't it? I'm going to set that, and I'm going to wiggle that like that, and that gets to be 33 and 5, which is prefect. So this baby's coming in at 6 pounds, look at that. So I tell people, usually you will go between this number that I have now, and full term will be another pound or pound and a half. So that's a normal size.

Michelle: Okay, so like 7, 7 and a half.

Dr. Lizellen La Follette: Exactly.

So the placenta is here. See the little calcifications of the placenta? Look at that. That's all amniotic fluid here. So the standard is to look at the placenta, get the measurement, get a weight of the baby, and do what's called a deep vertical pocket, which is basically measuring from here to – there's a little part in here you can't quite see. Any pocket that's more than 20 is considered adequate amount of fluid, and that's already 45.

So, head down, in the right direction, spine is up, normal measurement. None of that's going to change. Okay? I know it sounds really good.

Michelle: It sounds easy.

Dr. Follette: Exactly. Yeah, it's easy. Now you just gotta do the labor thing, exactly, okay.
