The Basic Pediatric (FAST) Focused Assessment with Sonography in Trauma

July 29, 2021
  • 00:15So when I do a fast, I usually start with
  • 00:18the right upper quadrant view and I'd like
  • 00:20to start in the anterior humoral line,
  • 00:23looking for rib space.
  • 00:24And and looking again,
  • 00:26we're going to illustrate a couple
  • 00:28of different movements.
  • 00:29One is this so called,
  • 00:31rocking looking superiorly entirely.
  • 00:32And this is called fanning,
  • 00:34looking anteriorly and posteriorly
  • 00:35and rotating sometimes if we
  • 00:37need to get between two ribs.
  • 00:39But this is a pretty good image.
  • 00:41Then I'm sliding up and down towards
  • 00:45inferior pole of the right kidney.
  • 00:48So that's a complete write
  • 00:49up a project video.
  • 00:59The next few, since we're in the territory,
  • 01:01we can do a sub typhoid view.
  • 01:03Again, you're putting the chance you
  • 01:05shirt it's a diaper region aiming up.
  • 01:07Sometimes it's easier to put the hand on
  • 01:09top of the transition and then a month,
  • 01:12and then Antonio is going to help me
  • 01:14change the depth so that it's part.
  • 01:19Again, that you might find this
  • 01:21difficult in the skinny patient,
  • 01:22it's very difficult to get a very good
  • 01:24window will show you on the cardiac
  • 01:26views where you can get a question along
  • 01:28Axis which looks very similar to this.
  • 01:38The next thing we look at is
  • 01:40left Upper Quadrant View,
  • 01:41where you can put your hand really
  • 01:43almost at the bottom of the bed.
  • 01:47Looking at the spleen again,
  • 01:49you're going to be fanning to
  • 01:51look more anteriorly that stomach
  • 01:52full of snack after school.
  • 01:54Looking closely fanning that gets
  • 01:56you the left kidney and sliding
  • 01:58up to see the rich shadow or the
  • 02:01diaphragm is sliding down to see the
  • 02:03inferior pole of the left kidney.
  • 02:07Ferguson artifact.
  • 02:08Do you have meddling or rib today?
  • 02:10I don't know some hydronephrosis.
  • 02:12Joshua this is so as muscle.
  • 02:22Super pubic you again.
  • 02:23You want to put the transducer
  • 02:25right over the pubic synthesis,
  • 02:26which is right here.
  • 02:29And then looking transversely first.
  • 02:33Any blood in any free through broadband blood
  • 02:36any free flight collect behind the platter,
  • 02:39either the transfers or the sagittal view.
  • 02:41Then you rotate the transducer with
  • 02:44indicator towards the head of the patient.
  • 02:46Again, the free fluid would be behind
  • 02:49in the colder sack in the female
  • 02:51patient behind the bladder, in the mail.
  • 03:02Remember the first examination you are
  • 03:04looking for an answer to the question.
  • 03:06Do I see free fluid? Yes or no?
  • 03:09It is either positive or negative.
  • 03:12It is not designed to tell you where
  • 03:15the fluid is leaking from or why the
  • 03:18patient is bleeding in the first place.
  • 03:20Fluid yes no.
  • 03:21Is the question we will answer.
  • 03:36This is what a pericardial
  • 03:38effusion would look like.
  • 03:39You can see how the heart seems pushed
  • 03:41to the side by a large amount of fluid.
  • 03:44This is a positive fast,
  • 03:46although the view obtained in this
  • 03:48case is a parasternal long axis and
  • 03:51not typically part of the fast.
  • 03:53We just wanted to show you what a large
  • 03:56pericardial effusion would look like.
  • 04:11You will see the liver closest to
  • 04:13the transducer and then the kidneys.
  • 04:16This is the positive or negative fast.
  • 04:21As you can see, there is
  • 04:23fluid in the Morrison's pouch,
  • 04:24so this fast is positive.
  • 04:26The CT scan on the right shows you
  • 04:28an intra abdominal fluid collection,
  • 04:30confirming that you were right.
  • 04:34Here you can see a very small dark
  • 04:36line between the liver and kidney.
  • 04:39It may be small,
  • 04:40but still counts as positive.
  • 04:42Remember, a fast is either
  • 04:43positive or negative,
  • 04:44not a little bit positive.
  • 04:59Is this positive or negative?
  • 05:02Yes, you know it.
  • 05:04There is fluid between the
  • 05:05diaphragm and the spleen.
  • 05:06It is positive.
  • 05:09Positive or negative?
  • 05:12Yep, you know it. It is positive
  • 05:13there is a small fluid collection.
  • 05:39Here you can see free fluid
  • 05:41behind the bladder representing
  • 05:42a positive fast examination.
  • 05:44As you can see on the picture on the right,
  • 05:47it was confirmed by a CT scan.
  • 05:51Alright, ready for some cases.
  • 05:54I want you to first name the view and
  • 05:56second point out the pathology. Let's go.
  • 06:05Yes, you're right,
  • 06:06we used a curvilinear probe and this
  • 06:09is the right upper quadrant view.
  • 06:11The fast is positive.
  • 06:13You can clearly see free fluid
  • 06:15on the left lobe of the liver.
  • 06:17And at Morrisons pouch.
  • 06:19Ready for the next one?
  • 06:27Good job, we were using a
  • 06:29curvilinear probe and this is
  • 06:30the right upper quadrant view.
  • 06:32It is positive because there is
  • 06:34a tiny amount of free fluid at
  • 06:37the inferior pole of the spleen.
  • 06:40OK, advance to the next slide.
  • 06:42Take your time.
  • 06:55Yes, we used a curvilinear probe and
  • 06:58we're looking at the right pleural space.
  • 07:01You correctly identified the
  • 07:03pleural effusion. We will cover the
  • 07:06lung and pleural pathologies in a
  • 07:08separate lecture though. Next case.
  • 07:17We used a curvilinear probe
  • 07:19and this was a pelvic view.
  • 07:21It is positive for free fluid.
  • 07:24Remember, in pediatric cases,
  • 07:26most positive fast scans
  • 07:27are seen on pelvic views,
  • 07:30in contrast with adults where
  • 07:32the Morrisons pouch view is
  • 07:34the most commonly positive.
  • 07:37Stromberg one less case,
  • 07:38and you're done.
  • 07:47Perfect, we used a phased array transducer
  • 07:50and this was a subset food view.
  • 07:53There is a large pericardial effusion.
