- Hello, my name is Phil Perera,
and I'm the emergency ultrasound coordinator
at the New York Presbyterian Hospital in New York City,
and welcome to SoundBytes Cases.
In this module, we'll continue our journey,
looking at the views of the Trauma FAST exam.
Hopefully you've had a chance to join me prior
for the views of the right upper quadrant,
and in this module,
we're going to look specifically
at the left upper quadrant views of the Trauma FAST exam,
known traditionally by two terms,
the splenorenal, or the perisplenic views.
In an upcoming module,
we'll look specifically at the suprapubic view,
or bladder view, of the Trauma FAST exam.
There's a lot of information we can gain
by looking at the left upper quadrant
in our trauma patients,
and we'll need to know that it's not a mirror image
of the right upper quadrant,
that the spleen offers less of an acoustic window
onto the left upper quadrant than the liver does
on the other side.
Here's a slide reviewing how to perform
the left upper quadrant view of the Trauma FAST exam.
As the spleen offers less of an acoustic window
on the left upper quadrant,
we need to bring the probe in
from a more posterior position.
Thus, the mantra, knuckles to stretcher.
Optimally, we're using a smaller footprint probe
that can get in between the ribs
and get a good view into the left upper quadrant area.
Position the probe in the long axis view
with the probe marker towards the patient's head,
at about the midaxillary line, or posterior axillary line,
with your knuckles almost touching down to the bedside.
We'll concentrate on two areas, most importantly,
the area above the spleen and below the diaphragm,
where fluid will preferentially accumulate,
but rounding out our exam,
we'll look inferior at that spleno-renal space.
Now that we know how to perform
the left upper quadrant view of the Trauma FAST exam,
let's take a look at a normal ultrasound image.
I have the probe oriented towards the patient's head,
so superior chest cavity is towards the left,
inferior abdominal cavity towards the right.
Notice the spleen,
the large organ in the middle of the image here,
and the kidney, the football shaped organ,
as seen inferior and posterior to the spleen.
Notice the curving white line just above the spleen,
which is the diaphragm.
Recall that in the left upper quadrant,
that fluid will accumulate preferentially
in between the spleen and the diaphragm
and will be a dark or anechoic stripe positioned there.
Here's another normal video clip
taken from the left upper quadrant.
In this case, I'm swinging the probe from inferior,
looking at the spleno-renal interface,
to superior, looking at that infra-diaphragmatic space.
And here, as I freeze the image,
we see the spleen right in the middle of the image,
the curving white line making up the diaphragm,
and notice the thoracic cavity
as seen just left, or superior, to the diaphragm.
If the patient had a significant hemothorax,
or fluid collection in the thoracic cavity,
that would be represented by
a dark or anechoic fluid collection
just above the diaphragm in the thoracic cavity.
Now that we've had a chance
to examine several normal video clips
as taken from the left upper quadrant,
let's look at a pictorial here,
showing a positive left upper quadrant FAST exam.
Here we see superior located to the left,
inferior to the right.
We see the spleen in the middle of the image,
the kidney inferiorly to the right.
The thoracic cavity with the diaphragm
to the left of the spleen, or superior.
We see the area of fresh fluid
as demarcated by the orange color,
and notice that it layers out
predominantly below the diaphragm
and above the spleen,
and this is the area where fluid
will preferentially deposit in the left upper quadrant.
There are ligaments that sling
from the diaphragm all the way to the colon
that prevent the flow of fluid
into that area between the spleen and the kidney
until the fluid is relatively large
within the left upper quadrant.
So, now let's take a look at a positive exam
from a trauma patient,
and we see here the spleen in the middle of the image,
the kidney inferiorly located to the spleen,
and notice the large amount of fresh fluid,
that dark or anechoic fluid collection
that layers out above the spleen
in the infra-diaphragmatic location,
and anterior to the spleen.
This indicates a large amount of fresh blood
in the left upper quadrant,
and we also see a blood clot,
that echogenic material waving around
anteriorly to the spleen.
So a positive exam in a trauma patient.
Here's another positive left upper quadrant view.
Notice here, there's a larger amount
of fresh fluid present on this examination.
We see the spleen in the middle of the image,
the kidney inferiorly there to the right,
and all the dark, fresh fluid,
as indicated by the dark, or anechoic, fluid collection,
as seen infra-diaphragmatic and above the spleen.
Notice again that the fluid is not
preferentially layering out in between
the spleen and the kidney, reinforcing the point that
this is not a mirror image of the right upper quadrant.
Here's another positive examination
in a patient who comes in hypotensive
after being hit by a car.
Notice I'm swinging the probe
between the kidney, up superiorly,
to look at the spleen.
Notice the absence of fluid in between the spleen
and the kidney,
but the presence of free fluid
right above the spleen and below the diaphragm
as indicated by that dark stripe.
Here's an interesting video clip from a trauma patient.
Again, we're looking at the left upper quadrant,
and we delineate the spleen and kidney.
Notice the presence here of fresh fluid,
the dark or anechoic fluid stripe
as seen layering out superior, or in anterior,
to the spleen there,
but let's look above the diaphragm here,
which we see as the curving white line
moving up and down as the patient breathes,
and what we notice here is the presence
of a dark fluid collection within the thoracic compartment.
So we're able to diagnose in this patient
an associated hemothorax
in addition to the hemoperitoneum.
So the left upper quadrant view
also helpful for looking into the thoracic compartment
as well as diagnosing interabdominal injury.
One maneuver that can help you
uncover fresh fluid within the left upper quadrant
is to have the patient take a deep breath
and analyze that infra-diaphragmatic space
as the diaphragm moves upward, off of the spleen.
Notice here that we uncovered the amount
of fresh fluid that's present right above the spleen
and below the diaphragm as the patient
takes a deep breath,
and that diaphragm moves superiorly.
So, in conclusion, I'm glad I could share with you
this SoundBytes module, going over the trauma FAST exam,
specifically the left upper quadrant, or perisplenic view.
There's a great deal of information that we can gain
by looking into the left upper quadrant
in our trauma patients,
and it's important to realize that
the left upper quadrant is not a mirror view
of the right upper quadrant,
and that fluid will preferentially layer out
in the area above the spleen and below the diaphragm,
in contrast to the hepatorenal space
on the right upper quadrant.
So, I hope to see you back as SoundBytes continues
and we move on to look at the suprapubic,
or bladder view, of the Trauma FAST exam.

- Hello, my name is Phil Perera and I'm the Emergency
Ultrasound Coordinator at the New York
Presbyterian Hospital in New York City.
And welcome to Soundbytes Cases.
In this Soundbytes module we'll continue
our journey looking at the Trauma Fast Exam.
I hope you've had a chance to join me prior
for modules looking at the right upper quadrant
and left upper quadrant views of the Trauma Fast Exam.
In this module we will specifically look at
the Suprapubic view, also known as the bladder or pelvic
view of the Trauma Fast Exam.
There is a lot of information we can gain
from looking at the Suprapubic view,
as we can potentially detect a smaller amount of fluid
than is required to make a positive right
upper quadrant or left upper quadrant view.
Literature suggests that only about
100 to 200 ccs of fluid can be detected
accurately on the Suprapubic view.
Here's a slide reviewing how to perform
the Suprapubic view of the Trauma Fast Exam.
In contrast to the upper quadrant views,
where we looked only in the long axis configuration,
the Suprapubic view is made up of two planes.
We want to look in both long and short axis configurations.
We'll begin at long axis with the marker dot
oriented toward the patient's head
and complete our exam by moving the probe
into short axis with the marker dot
toward the patients right side.
This way we can fully scan through the pelvis
and not miss any small amounts of fluid there.
It's optimal to perform the examination
with a full bladder as an optimal
acoustic window, so perform the
exam prior to having the patient
void or placing a foley catheter.
Here's an illustration showing the anatomy
that we'll need to know to perform
the Suprapubic view of the Trauma Fast Exam.
We see the pattern of fluid flow in a female,
to the left here, and a male, to the right.
Let's look closer at the female pelvis,
to the left, and what we see is that fluid will
preferentially develop in the pelvic
Cul de Sac, located behind the uterus.
Now, small amounts of fluid will only be
located in the pelvic Cul de Sac,
but as the amount of fluid enlarges
it will come out and increase so
that it will layer out on top of
the uterus and on top of the dome of the bladder.
But small amounts of fluid will only be found in
that pelvic Cul de Sac posterior to the uterus.
Now let's take a look at the male
pelvis to the right and we see
small amounts of fluid that will only be found
in the Retrovesical Space behind the bladder.
As the amount of fluid enlarges it
will come anterior to settle out
over the top of the dome of the bladder.
But as we emphasized in the female,
small amounts of fluid will only be
found in one place and in the male
it will be in that Retrovesical Space
immediately posterior to the bladder.
Let's begin by looking at some normal
video from the Suprapubic View.
In this case, a long axis view in a female,
superior to the left, inferior to the right.
The first structure we identify is
the bladder, the dark area, anteriorly
and posterior to the bladder we see the uterus.
Now if we look into the potential space,
the Pelvic Cul de Sac, posterior to the
uterus for any dark fluid collections, we see an
absence of any fluid on this normal video clip.
Now let's inspect a video clip from a male.
In this case a short axis view.
We see a large bladder there, anteriorly
and behind the bladder we see two
tubular structures making up the
Seminal Vesicles, a normal finding in a male.
Now if we're looking for free fluid
behind the bladder, we'd be looking
for dark or anechoic fluid collection
layering out behind the bladder.
Notice this is a normal examination.
Here's a positive examination
in a female trauma patient.
We're looking in the long axis view,
superior to the left, inferior to the right.
The first structure we identify is
the bladder, as seen inferior here.
And notice the uterus, the solid organ,
as seen superior to the bladder.
We note the parts of the uterus, the fundus
anteriorly, and the cervix more posteriorly.
Now let's look into the Pelvic Cul de Sac
immediately posterior to the uterus,
and what we see here is the presence of a
dark or anechoic fluid collection just posterior
to the cervix within the pelvic Cul de Sac.
So in the female trauma patient,
this does denote a positive examination
and can be a sign of ongoing bleeding
within the abdominal pelvic cavity.
So let's contrast this clip in which
we see a small amount of fresh
fluid within the pelvic Cul de Sac.
With this one, in which we have a female
trauma patient with a large amount
of bleeding within the pelvic cavity.
We see here, again, a long axis scan superior
to the left, inferior to the right, the bladder
we see as the dark structure inferiorly
and the uterus superior to the bladder.
Notice the fresh fluid as seen posterior
to the uterus within the Cul de Sac,
but note that the amount of fluid
comes anterior to the uterus,
as seen here between the uterus and the bladder.
So this denotes a large amount of blood within
the pelvic cavity in this female trauma patient.
If we now orient the probe to the patient's right side,
we obtain a short axis view of the same patient.
And what we see here is the uterus in the
middle of the image and notice the large amount
of fresh fluid as seen both to the top, or anterior,
to the uterus and posterior to the uterus.
Notice in this case we can see the
broad ligaments of the uterus well outlined
by all the fresh fluid within the pelvis.
So a large amount of fresh fluid, or blood,
in this case, within this female trauma patient.
Here's a positive examination
Suprapubic View, short axis in a male.
Probe is oriented towards the patient's right and
anteriorly we see a large, fluid filled bladder.
Posterior to the bladder, in the retrovesical
space we appreciate the presence of free fluid,
as shown by that dark or anechoic
fluid collection there.
Now this gives a finding known as
the double wall sign, and we see
the wall of the bladder, outlined by
the urine inside the bladder, and the
blood, in this case, outside the bladder
in the area of the retrovesical space.
To further confirm that the last patient
had a positive exam and that we're
not mistaking areas of fluid as seminal vesicles,
we'll re-scan the patient in the long axis plane,
superior to the left, inferior to the right.
We see the large circular bladder,
as seen anteriorly and superior
and posterior to the bladder in the
retrovesical space, we can see
free fluid layering out there.
This confirms that indeed the patient
has a positive exam, with blood
layering out behind the bladder.
And, again, we see the double wall sign,
urine outlining the inner wall of the
bladder, and blood, in this case,
outlining the outer wall of the bladder.
Here we're scanning a male trauma patient with
a long axis configuration and we see a large
amount of free fluid within the pelvis.
We note the bladder inferiorly,
and note all the free fluid layering
out both posterior to the bladder
in the retrovesical space and coming
anteriorly onto the dome of the
bladder as seen to the left here.
So a large amount of free fluid in this male trauma patient.
In conclusion, I'm glad I could
share with you the Soundbytes Module
covering the Suprapubic View of the Trauma Fast Exam.
This view is a very important
one to add onto the exam of your
trauma patient as we can potentially
detect a smaller amount of fluid here,
within the pelvis, than it takes to
make a positive right upper quadrant
or left upper quadrant view.
Remember that this is a two-step exam,
we'll be looking in both short
and long axis configurations to
verify fluid, and also remember
the differences between the female, where we're
looking into the pelvic Cul de Sac for fluid,
and the male, where we're looking into
the retrovesical space for fluid.
So I hope to see you back in the
future as Soundbytes continues.

- Hello, my name is Phil Perera
and I'm the Emergency Ultrasound Coordinator
at the New York Presbyterian Hospital in New York City
and welcome to SoundBytes Cases.
In this module entitled,
Part Two of the Right Upper Quadrant View
of the Trauma Fast Exam,
we're going to focus entirely on positive findings
from this view.
Hopefully you've had a chance to join me prior
for Part One of the Right Upper Quadrant View
of the Trauma Fast Exam where we focused entirely
on normal findings from the right upper quadrant.
And hopefully have a chance to join me back
as we go through the left upper quadrant
and suprapubic views of the Trauma Fast Exam.
So let's begin this module by going through a
review of how to perform
the right upper quadrant view of the Trauma Fast Exam.
Remember that the probe is positioned in the
long axis configuration with the marker dot superiorally
and that we're going to place the probe in between the ribs
at about the anterior axillary line.
Here we'll want to focus on the three areas
as I emphasized in Part One of this module.
Number one, the infra-diaphragmatic space
looking at that region just below the diaphragm
and above the liver,
and actually looking into the chest cavity for a hemothorax.
Position two, which is the traditional Morison's Pouch
or hepatorenal interface.
And position three, to round out the exam
looking at the caudal liver tip representing the
beginning of the right paracolic gutter.
Here's a nice illustration showing a positive examination
from the right upper quadrant view of the Trauma Fast Exam.
We see the liver smack in the middle of the image
and the kidney slightly posterior and inferior to the liver.
Let's look at the preferential deposition of fluid
as shown here in the orange color,
and we see that it layers out predominantly around
the caudal tip of the liver as shown towards the
inferior edge of the image here.
Notice that it flows from the caudal tip of the liver
into that potential space which is Morison's Pouch
in between the liver and the kidney.
Now this is very important to emphasize as many times,
fresh fluid can only be seen around that
caudal tip of the liver,
and then it would move into that hepatorenal interface
or Morison's Pouch.
Here's a positive ultrasound examination from a patient
who was hit by a car while crossing the street
and we see here the liver
smack in the middle of the image here.
Notice the kidney located inferior and posterior
to the liver.
And in between the liver and the kidney in that
potential space known as Morison's Pouch,
we see a dark or anechoic fluid collection.
Not insignificant,
actually a pretty large stripe in this patient.
This represents the positive examination,
or the presence of fresh fluid,
in this case blood within Morison's Pouch.
And notice that it layers out in between
that liver and kidney.
To emphasize the point that a complete right upper quadrant
view includes looking at the caudal tip of the liver,
let's examine this video clip from another trauma patient.
If we look at the hepatorenal interface there,
we fail to see the presence of any fluid,
but as we move the probe inferiorially,
we see that the caudal tip of the liver as shown right there
is well outlined by fluid.
And here we see the inferior pole of the kidney,
the caudal tip of the liver extending above the kidney,
and notice all the fresh fluid
both anterior and posterior to the caudal tip of the liver.
Making the point that this is a very important area
to look for in the right upper quadrant exam.
Here's a video clip from a patient who was stabbed
with a really big knife to the epigastric region.
And as we look at the right upper quadrant,
we can actually see a linear liver laceration
extending through the medial aspect of the liver.
We also appreciate the presence of a large
amount of fresh fluid.
That dark or anechoic fluid collection
layering out posteriorally there to the liver
and extending into Morison's Pouch,
the hepatorenal interface.
So as this patent had unstable hemodynamics,
the next move was to package for the operating room.
And here we can actually see the caudal tip of the liver
waving around in all the fresh fluid,
in this case blood.
And I obtained this view by moving the probe
one intercostal space inferior from the last view
to well delineate the caudal tip of liver
which we can see here moving around in all the fresh fluid.
In the last few video clips the appearance of fresh fluid
on bedside sonography was darker, anechoic.
However as blood clots it can take on a more echogenic
or lighter appearance.
In this video clip a patient was stabbed
and had a significant down time before being
brought to the Emergency Department.
As we look at the hepatorenal interface,
we see a large amount of clotted blood there
made up by that echogenic
or lighter appearance of the blood there.
Notice that the large amount of blood extends into
the right paracolic gutter as we scan inferiorially.
And here we can see the liver,
the kidney,
and the clotted blood,
that more echogenic or lighter blood in Morison's Pouch.
So in conclusion,
I'm glad I could share with you this Part Two Module
on the Right Upper Quadrant View of the Trauma Fast Exam.
I hope now you have a better understanding
on how to perform a complete exam
looking into the three areas as we discussed.
Infradiaphragmatic,
Morison's Pouch,
and inferior tip of the liver.
And hopefully now you'll be able to discern
the presence of fresh blood versus clotted blood
on bedside sonography.
So I hope to see you back as Sono access continues
and as we move further through the other views of the
Trauma Fast Exam.

- If you do a transabdominal examination
of the pelvis for early pregnancy
and you cannot find a definitive
gestational sack inside of the uterus,
the next step you need to do is
an intracavitary examination of the uterus
and cervix and the adnexal area
to determine where the pregnancy is,
whether it's intrauterine or extrauterine.
So what I'm gonna do right now
is walk through the steps on how
you would do that examination
and we're gonna use this Phantom by Blue Phantom,
that will actually demonstrate an ectopic pregnancy.
So the first stage of the prep
for the intracavitary transducer
is that we need to cover it with a sheath.
When you do this, we need to remove
any air gaps that are inside the sheath,
next to the transducer face.
So what we will do is put a little
bit of gel inside the cover,
position that over the tip of the transducer
and then just pull down the covering over the transducer
and pull this down right over the handle,
so you've got good coverage.
And then just make sure that you examine the tip here
and make sure you eliminate any
air bubbles that are covering the transducer face.
So once you've got the air bubbles eliminated,
then you can move on to the next step.
We're going to put a little bit
of gel on the outside of the latex cover now.
And again, your orientation for
this examination is very important.
So for the long ax or sagittal view,
we want the orientation marker up
and then when we go to the coronal view,
we're gonna turn that so it faces the patient's right.
After we've inserted the transducer in a long axis view,
the first thing that we're gonna
see is a long ax of the uterus.
In this Phantom representation of the uterus,
we see an endometrial stripe,
which is represented by the white line.
So if I was doing this as a real pelvic exam,
I would scan to the right of the patient,
all the way through to the right adnexa
and then back over, all the way back through the uterus,
over to the left adnexa.
And the reason I'm doing this
is because I don't see the pregnancy inside the uterus,
so I'm suspecting that it's extrauterine
or an ectopic pregnancy.
I do have some hints here though, using this Phantom.
In the posterior cul de sac region,
I'm seeing a black anechoic area,
which would represent free fluid or blood.
If I scan all the way over to the left adnexa, in this case,
the first structure I come across,
this echogenic area represents the ovary.
If I keep scanning to the left, in the pelvis,
I encounter this other area
and this represents, in this case, our ectopic pregnancy.
When I'm medial, just right beside the uterus,
I see the ovary and I scan out a little bit more
and this represents the ectopic pregnancy.
And this is what you should see,
a round, circular structure like this,
with a bright, echogenic brim.
And it is possible to sometimes
to see a fetal heartbeat inside
the ectopic pregnancy as well.
Now, I'm gonna change the orientation of the transducer,
so I'm in a coronal view.
To do that, I'm gonna turn the transducer counterclockwise.
The uterus will appear circular,
because I'm cutting a cross sectional view of it
and I tilt the handle of the transducer up,
to move inferiorly, down to the region of the cervix
and then bring the transducer handle
down to scan superiorly,
into the area of the fundus of the uterus.
Again, in this case, I can see that
there's no pregnancy inside the uterus itself.
If I scan over to the left of the Phantom,
again, we see the left ovary and then right beside it,
we see our representation of the ectopic pregnancy.
This bright, circular area.
Moving back towards the midline,
the anechoic area just posterior to the uterus
is represented as free fluid or blood, in this case.
So those are the views that you
would need to do a thorough assessment
of the pelvis for early pregnancy.

- Hello, my name is Phil Perera and I'm the emergency
ultrasound coordinator at the New York Presbyterian Hospital
in New York City, and welcome to SoundBytes Cases.
In this module we're going to focus entirely on
the trauma fast exam.
Specifically, we're going to look further into the
right upper quadrant view, also known as
the hepatorenal view.
Now, we're going to cover the two other views of
the trauma fast exam in upcoming modules of SoundBytes.
The left upper quadrant view, also known as
the splenorenal or perisplenic view,
and the suprarpubic view, also known as the bladder view.
There's a tremendous amount of information we can gain by
looking closely into the right upper quadrant area
in our trauma patient.
Traditionally it's been emphasized that the hepatorenal area
or Morison's pouch view, is the primary target for the
right upper quadrant, but it can take up to 600 ccs of fluid
to make a positive exam if only looking into that area.
So I'll show some alternative views in this module that can
help us to possibly improve on that number.
Now let's take a look at a slide showing us how to perform
the right upper quadrant view of the trauma fast exam.
We'll want to place the probe at about the anterior axillary
line and using the liver as an acoustic window aiming
the probe down towards the bedside retroperitoneally to get
a good view of these anatomical structures.
It's best to have a small footprint probe that can easily
sit between the ribs giving a good view on to this area.
Notice that this is a long axis view with a probe marker
position superiorly.
Now our first view from this right upper quadrant area
will be position one as shown here in the
infra-diaphragmatic space just below the diaphragm
and above the liver.
Second, we'll move the probe slightly inferiorly to look in
to the traditional Morison's pouch or hepatorenal interface,
and the last view is the caudal tip of the liver shown here
in position three.
It's very important to look at the caudal tip of the liver,
as this represents the beginning of the right paracolic
gutter and small amounts of fluid will pool here before
moving into Morison's pouch.
Now that we know how to perform the right upper quadrant
view of the trauma fast exam, let's take a look at a normal
image that you might obtain.
Remembering that this is a long axis view,
I have the probe marker here positioned towards
the patient's head.
So towards the left of the clip here is
superior chest cavity and towards the right is
inferior or abdominal cavity.
Notice the first large structure that comes into view
in the middle of the image is the liver and to the right,
or inferior to the liver we see the football shaped kidney.
Now it's that interface between the liver and kidney that
represents a potential space known as Morison's pouch
where we're be looking for dark, anechoic fluid collections.
Note here, we see a thin, white line making up a normal exam
and representing the fat within the capsule
around the kidney.
Notice to the left of the liver we see the white diaphragm
that represents the interface between chest
and abdominal cavities.
Let's take a look at another normal
right upper quadrant examination.
Again the probe marker is towards the patient's head.
This is the superior chest cavity towards the left.
Inferior abdominal cavity towards the right.
We see the liver in the middle of the image,
and notice the diaphragm above the liver moving up and down
as the patient breathes.
We see the kidney inferior to the liver, and notice
the potential space in between the liver and the kidney
that makes up the hepatorenal fossa or pouch of Morison.
Notice in this video clip all we see is a white line
representing the fat within the capsule around the kidney
or Gerota's capsule.
If there was fluid, we would see a dark or anechoic fluid
collection in this potential space.
Let's now look at the diaphragm which we see above the liver
and if we look above the diaphragm this is where we would
look for fluid within the chest cavity or hemothorax
in the trauma patient.
We may have to move the probe several intercostal spaces
on the patient's side to fully investigate
the right upper quadrant for fluid.
Here's a swing view where I'm starting relatively superior
right there looking in the area between the diaphragm
and the liver, going through Morison's pouch, as I'll show
coming up right here the area between the liver
and the kidney and terminating at the inferior
tip of the liver.
Notice here we notice the caudal tip of the liver extending
almost all the way inferiorly down past the inferior pole
of the kidney, and it's important to look at that caudal
tip of the liver, as it represents the beginning
of the right paracolic gutter.
So in conclusion, I'm glad I could share with you part one
of the right upper quadrant view of the trauma fast exam.
Now we know how to recognize a normal examination
looking all the way from the area below the diaphragm
through Morison's pouch and terminating at a view of
the caudal tip of the liver.
So I hope to see you back as SoundBytes continues,
and we look at part two of the right upper quadrant view
focusing on positive examinations.

- [Voiceover] A curved, or phased array transducer,
with a pelvis exam type,
is used to perform the pelvis ultrasound exam.
A full bladder is used as an acoustic window
to view the pelvic organs.
The pelvis is evaluated in two plains.
Place the transducer in a long axis position
with the orientation marker to the patient's head,
at the level of the symphysis pubis.
Angle the transducer inferiorly into the pelvis.
The bladder appears in the near-field of the image,
as a hypoechoic triangular structure.
The uterus is gray in appearance
and located either directly posterior
or superior to the bladder.
The endometrial stripe will appear as
a bright echogenic line from the fundus to the cervix.
The uterus does not always lay directly in the midline
so it may be necessary to slightly rotate the transducer
to view the entire length of the uterus.
Sweep the transducer from side to side
to see the entire uterus.
The ovaries may be seen by sweeping the transducer
to the lateral aspects of the pelvis.
They are almond-shaped and slightly hypoechoic structures.
Follicles may appear as multiple
hypoechoic, cystic structures within the ovaries.
Some follicles may be quite prominent,
depending upon the luteal stage.
To obtain a transverse view of the uterus,
rotate the transducer 90 degrees,
so the orientation marker is to the patient's right.
The bladder appears more rectangular in shape in this view.
Sweep the transducer superiorly
from the level of the cervix to the fundus
to see the entire uterus.
The ovaries will be seen on either side of the uterus
and can vary in location,
from a superior to inferior position.

- We're gonna do the FAST exam,
the pelvic view in a female now.
Again we have the phase array transducer,
here's our probe marker right here,
I'm gonna start off with a sagittal view.
And ideally, the (slurred) bladder is full.
So you go just above the symphysis pubis,
so we're scanning down here sagittaly,
and some of the anatomic landmarks
that we're looking at,
at the very top of the screen is the bladder,
which is an anechoic structure,
fluid filled, obviously with urine,
it's got nice walls around it.
Just below that is the uterus,
which is a pear-shaped organ.
You can see it well visualized
because the bladder is full.
And just below that
is a potential space, the Cul de Sac,
where we can look for, very carefully,
small amounts of free fluid.
When we scan this patient,
in this view, in the sagittal view,
from the patient's left to the patient's right.
And we're slowly slowly scanning to see
if there's any evidence of free fluid.
Once we finish the sagittal view,
we want to go ahead and do a transverse view.
What we're gonna do now
is point the transducer marker toward the patient's right.
So we're gonna rotate that transducer,
toward the patient's right.
Again, we see the bladder in the center of the screen.
We're now gonna scan from inferior,
just below the symphysis, to more superior,
and in between we're also gonna identify the uterus.
So we're going right to the very top of the bladder,
to about mid-bladder,
we can see the uterus here in the center.
A very small amount of free fluid here,
which can be physiological as well.
So we're scanning all the way inferiorly,
to more superiorly, we see the uterus,
we actually see part of the ovary there,
and then we're gonna go all the way more superiorly.

- The next view I'm going to take you through
is a perisplenic or left upper quadrant view.
This view tends to be a little bit more difficult
because the spleen is smaller and doesn't provide
as large an acoustic window.
We're going to start.
Again, the patient's going to be supine.
This is a probe marker right here.
We're going to go really posterior.
My hand is going to touch the gurney.
You can go about four finger breadths
just above the costal margin.
You can identify the kidney.
That's going to be a pretty identifiable organ,
characteristic bean shape.
Then we can see it here on the screen.
Just above it, we're going to see the spleen.
To the far left of the screen as well
we see the diaphragm.
Once you're in this location,
you want to carefully pan through
the inferior part of the spleen,
and then jump over that rib,
and see the superior part of the spleen,
because fluid often collects just above the spleen
and below the diaphragm.
Once you identify a good view in the left upper quadrant,
you'll want to do a sweep through that area
looking for free fluid.
Again, you see the kidney, you see the spleen.
Find the interface between.
Look for fluid between those two organs.
Then particularly scan above that spleen,
scanning all the way through the organ,
looking for free fluid above the spleen
and below the diaphragm.
Again, when you're scanning through this area,
you want to carefully look above the diaphragm
for evidence of hemothorax.
When you're scanning in this view,
also make sure you scan the full kidney.
Here we see the superior pole to the left of the screen,
and the inferior pole.
You want to make sure you get that full kidney
in view when you examine the left upper quadrant.

- So the patient's gonna arrive in a supine position,
they'll often be on a backboard as full spinal precaution,
so motion of the patient will be impossible.
We're gonna choose our transducer.
We have chosen the phased array transducer,
we're gonna put a little gel on top of it.
And I like to put the probe marker
toward the patient's head, toward the axilla,
at about the midaxillaral line, 10 to 11th ribs.
Another easy tip to find out the location
is get to the costal margin,
go about three finger-breadths above it,
and you should be able to find the kidney
and see the adjacent liver.
I'm just adjusting my gain here.
And already I can see the interface
between the kidney and the liver, which is Morison's pouch.
So what we see here, on the bottom,
this crescent shaped organ, is the kidney.
Above it we see the liver,
and just to the left side of the screen
we see the diaphragm.
So when I'm examining this area,
I'm gonna carefully scan through
the entire area of Morison's pouch,
including at the liver tip.
So we see this whole area here
looking for an anechoic stripe.
An anechoic stripe would be indicative of free fluid.
I'm also identifying the diaphragm,
so when I look at the diaphragm,
this is the hypoechoic or white line
to the left side of the screen,
and I should be able to see that pretty easily
and you can see what appears to be
liver on both sides of the diaphragm,
on the bottom far left of the screen.
That is mirror artifact and is a normal finding.
If the patient had a pleural fluid collection after trauma
that would be a hemothorax,
we would see an anechoic or black area in this location.
