hello dolls it's me Babs and today we're going to talk about the anatomy scan
the 20-week big scan when you finally get to know the gender of your baby
so congratulations you've made it this far you're halfway there
now at this point you may have had a gyn scan at some point before you got
pregnant or if you hadn't had a scan before you got pregnant you may have had
a scan around six to eight weeks I'm going to link the video somewhere here
so you could see if it matches what you went through also you may have had the
NT scan or the first trimester screening scan where we measure the back
of the neck and now finally it's time for the 20-week scan this scan is a
diagnostic medical ultrasound exam basically just like when you go to the
doctor to get an exam done this is the exact same thing except it's with the
fetus and with an ultrasound we do this scan around 18 to 20 weeks and we try to
finish it by 23 weeks some places might stretch it to 24 weeks in this video I'm
gonna go over what you might experience during your exam and everything that
we're looking for in your baby and I'm solely going to focus on healthy low
risk pregnancies meaning your baby is genetically normal you have no
complications previous pregnancies have been normal if you have had a previous
pregnancy and you are at a healthy weight now some places might do this
exam in two parts the first part would be on top of the on top of up okay the
first part will be on top of the belly we'll look at the baby from head
to toe the second part is done vaginally that word sounds familiar and it should
sound familiar because I did a video on pelvic ultrasound and what you should
expect during your exam this is a GYN exam or if you're pregnant at 8 weeks we
do the same thing we check on top and then we check vaginally in the anatomy
scan we do the exact same thing now not every place will check your cervix
that's why we're checking vaginally we want to make sure that your cervix is
closed and long with nothing in the way okay so when you come in you may or may
not be asked to get undress depending on the place and depending on whether
they're gonna check your cervix or not transvaginally regardless you don't
need a full bladder at least in a lot of places because your baby's big enough
that we can see without a full bladder if you want to know why we might need a
full bladder to check your baby when your baby is smaller make sure you watch
my public ultrasound video it explains everything so you lay down on the table
or on the exam bed and you show your belly now I can't promise you that the
gel is gonna be warm but sometimes it is and sometimes it's not so prepare
yourself the first thing we check is the presentation now what does that mean
presentation just means the position of the baby is the baby head down by your
cervix is the baby head up with the tush by the cervix or is it transverse
meaning is it laying across your belly when the baby's head is down that
presentation is called vertex when the baby's head is up that presentation is
called breech
breech is not an emergency let me ask you this and please leave the comment
down below what do you think breech means because many times when I tell the
patient that the baby's head is up and I write the word breech on the monitor
they tend to freak out but I'm not sure they know why they're freaking out I
just told them that breech just means the position of the baby but why don't
you tell me down below what you think breech means also sometimes I have
patients freak out when they hear that the baby's head is down by the cervix
that's also okay that doesn't mean that the baby's coming now that just means
that the baby's head is down there I mean the baby's head has to be somewhere
right? and the baby could be positioned in any way that it wants once we get the
presentation we get the baby's heart rate right away after that we try and go
in order from head to toe we look at the brain we look at the different parts of
the brain right side left side and the back of the brain called posterior fossa
we measure different parts of the brain and we also look at the shape and the
size of the skull from there we look at the face now there's the front of your
the face and there's the profile of the face nobody likes the front of
the face and why is that because it looks like this everybody
wants this picture of the baby now here is when everybody wants a picture of the
profile and if you don't get a 3d picture watch my video on why you didn't
get a photo of your baby and then you know why we look at everything in the
face the eyes the nose the lips - chin we don't really look at the ears at
least in the places that I have worked in we don't look at the ears but some
places might next are the arms and the hands I like
to take a picture of the hands like this but some places they take pictures of
the hands like this next we take pictures of the spine now it would be
great if we could see the whole spine in just one shot but most of the time we
don't we have to take pictures of the spine
in segments next are the organs of the baby kidneys stomach bladder diaphragm
even the bowels liver we may it really depends on where you're getting your
exam the liver is not really something that we look at unless we see something
there next is the heart we take a lot of pictures of the heart now here's a
disclaimer for you parents if we take a lot of pictures of the heart that
doesn't mean that there's something wrong even though sometimes yes but this
is not what this video is about we're talking about healthy normal pregnancies
and normal babies if we take a lot of pictures of the heart it could be one of
several reasons or all of these reasons we're not getting that picture perfect
image so we keep taking pictures over and over and over the baby's not in a
great position to get the perfect pictures or the baby's moving a lot so
it's hard to get the perfect picture so a lot of the times this is what happens
we'll start taking pictures of the baby we'll start taking pictures of the heart
we stop because the baby changed positions we looked at something else
and then we go back to the heart now some techs I know I do this might finish
the exam and I'm getting a little ahead of myself but we might finish the exam
look at our pictures and decide oh I could get better images I'm gonna go
back and take more pictures that doesn't mean there's something wrong it just
means we want to get perfect pictures and we're gonna go back and get them
okay I took a break and I don't remember where I left off so I'm just gonna say
that it's time for part two the transvaginal portion future Babs here
letting you know that that is not the end I accidentally deleted a footage of me
explaining everything else that we're going to check during your Anatomy scan
I completely deleted the part where I say we're going to look at both femurs
and the bones of the calves and the feet some places might measure the bones of
the calves or the lower legs the tibia and the fibula also some places might
measure the bones of the forearms the ulna and radius and I have mentioned
before that we measure the skull or the head we also measure other parts of the
baby just to make sure that it's growing appropriately for the gestational age so
the three things that we have to measure are the head there are two parts of the
head that we have to measure the head circumference and the B P D then we
measure the abdominal circumference next is the femur thank you for watching and
leave your questions down below and check out my other videos that I have
for you ciao
