Case 1 - Orogastric Tubes

HIDE
PrevNext

0:00

This is an ER patient who presented to

0:03

Radiology for PA and lateral view of the chest after

0:06

two placement to confirm adequate placement.

0:09

And so here are job is to make

0:12

sure that the lines and tubes are projecting in

0:15

the right spaces oftentimes. These are done

0:18

as portable examinations, and it may be hard to

0:21

actually low collides.

0:24

The depth of a line without the lateral View and

0:27

so in those situations, I'll usually talk about how and

0:30

where a line or two projects versus

0:33

having a lateral and an AP

0:36

where you can tell much better where it's actually

0:39

placed. So that being said, let's take a look at this examination

0:42

here.

0:44

Where you do see lines and twos monitoring wires that are

0:47

overlying the patient. That's not why we're here.

0:50

We're actually looking at the course of the autographic tube

0:54

that's in place, which you can see coursing along the esophagus

0:57

which is a normal expectation and

1:00

you obviously want to see the weighted tip fall

1:03

below the diaphragm. However, it's moving off to

1:06

the right side and it's not really following the normal and

1:09

expected view which would be to curve toward the GE Junction and

1:12

to land in the stomach. So this is the gastric bubble

1:15

here and we're heading in the wrong direction. So

1:18

if we do a little bit of window and leveling, we'll

1:21

see the course a little bit better and this

1:24

is actually going into the airway along the

1:27

trachea along here.

1:29

Down along the very slight angle into the

1:32

right lower lobe bronchus and

1:35

his wedged very peripherally in the

1:38

lower lobe of the right lung now

1:41

you may or may not believe me, but we've got a lateral view so

1:44

that we can actually confirm this.

1:46

And what we see again is the endotrachal tube

1:49

in the airway and it's coursing posteriorly

1:52

away from the stomach which the

1:55

G Junction should be here and it's wedged here in the right lower lobe.

1:59

So this is obviously not ideal in terms of the placement.

2:02

You want to call the clinicians immediately and

2:05

have them remove completely the tube

2:08

and start again. Obviously. If we

2:11

were to leave it here the patient were to get fed will have a massive

2:14

aspiration event on our hands, which is not ideal for

2:17

the patient.

2:18

We want to take a look at the other aspects of the

2:21

radiograph. So again take a look at the lung Fields. The left

2:24

lung field is clear. There's some scatter atelectasis

2:27

on the right side. The mediastinum

2:30

looks fine. There's unfolding of

2:33

the aorta here. We see sternotomy wires,

2:36

and the Heart itself is not enlarged.

2:40

The bones will also review to make sure that there's

2:43

no obvious lesion. There's no fracture even

2:46

though we're doing this for a tube check. We

2:49

want to make sure that we're again consistently looking for any and everything

2:52

that could be and should be reported below the

2:55

diaphragm and then the soft tissues so really in

2:58

this patient with a question of line and

3:01

two placement the oral gastric tube

3:04

is

3:05

Ectopically placed in the right lower lobe bronchus

3:08

and really kind of wedged in the lung. We want to

3:11

get that removed immediately.

3:13

We do have some follow-up cases that are very similar. So oftentimes

3:16

following the path of least resistance. The

3:19

right lower lobe is the recipient of these errantly

3:22

a placed tubes, but you

3:25

can also see them on the other side.

3:28

So this is a case again done for the same reason

3:31

where the oral gastric tube heads down

3:34

the left main stem Broncos and you might say well it's heading

3:37

to the left and we think that it's actually in the

3:40

stomach and it just needs to be advanced.

3:42

However, when you look at the angle and where

3:45

the esophagus should run it doesn't

3:48

really cross midline and come into the stomach right here,

3:51

but if you look at the airway, you can actually see the left lower lobe

3:54

bronchus here and that's sitting and projecting

3:57

over that area.

3:58

So if we look at it on the edge enhanced views

4:01

again, you can see that it's really crossing midline

4:04

a little bit too early. And this is probably also wedged

4:07

in the left lower lobe. We don't have a lateral

4:10

on this one. So we did alert the clinician to remove

4:13

the tube and to start fresh.

4:16

In terms of looking at some of the complications and things

4:19

that can happen. Again. We have a similar

4:22

case with a patient who has been

4:25

intubated and has had an

4:28

oral gastric tube placed and the requisition was for

4:32

Are we in the right spaces? So again, you don't want

4:35

to get distracted by things that are shiny and new or

4:38

things that are just shiny like all this contrast material

4:41

that's been aspirated here. But you do want to

4:44

just go through methodically and ask yourself the question each and

4:47

every time am I missing something what about this? So

4:50

kind of going through systematically?

4:54

Looking at lines and tubes. There's an endotracheal tube. That's right along here.

4:58

And when we look at and try to window and level into where the Karina

5:01

is, this is really sitting right at the level of the Purina and

5:04

probably should be retracted. So the recron is

5:07

sitting right here the tube is sitting right here. So there's less

5:10

than a centimeter distance there. Ideally you

5:13

want to have it a little bit higher. So it would recommend retraction of

5:16

the endotracheal tube. This patient also

5:19

has an oral gastric tube, which as we follow it

5:22

along the course. It doesn't really hug the right side. The

5:25

patient is a little angulated. So you kind

5:28

of just follow it for a while. It's heading really far to the

5:31

left.

5:32

Well before you get below the diaphragm, we would expect

5:35

the GE Junction and following it around it leaves

5:38

the edge of the film. So we lose it. But the weighted

5:41

tip comes back into the field of view. And while this is

5:44

below the diaphragm, which ultimately you want to get below the

5:47

diaphragm. This is really perceptual. And remember that

5:50

on this frontal view the diaphragm which is cup shaped is

5:53

actually kind of diving deep right here. And if

5:56

you follow the orientation and the projection pathway

5:59

of the oral gastric tube, it's in the

6:02

long. It's following the airway right here. It's following the left lower low

6:05

bronchus and it's wedge deep deep deep into the

6:09

posterior sulcus on the left and it's

6:12

sitting below the diaphragm. In fact, it is sitting in the loan.

6:15

So again, we'd want to call very quickly and tell

6:18

them to remove this. We'd also want to make sure that because of

6:21

the topic placement we're looking for any evidence of

6:24

complication so they didn't feed the

6:27

patient on this view. So I think some of the contrast material that we see along

6:30

is not from this event. They

6:32

Have not gotten a Radiologists involved in reviewing

6:35

this case before and they fed without getting it

6:38

checked. But we also want to take a look at the lungs

6:41

and as we do that one thing that I'll

6:44

bring to your attention. Is this line along here.

6:47

And this patient also has a pneumothorax which as a

6:50

complication for this placement. They've probably

6:53

moved through parenchyma and out into the pleura

6:56

and we now have

6:58

a pneumothorax. There's no evidence of tension the right

7:01

side of the lung looks fine. We've talked about the basilar opacities

7:04

the heart and mediastinum given

7:07

the portable technique look fine take a look at the bones and

7:10

they're fine as well as a soft tissues.

7:13

Just as a edge enhanced image. It's

7:16

the same image. You can again see the pneumothorax along here.

7:19

You see the tube coming

7:22

down and really in the lung while it

7:25

projects below the diaphragm. It's actually just wedged within the lung and

7:28

you can see how low the endotracho tube tip

7:31

is in comparison to the Karina and it's

7:34

really sitting there. So both the endotracheal tube and the oral

7:37

gastric tube need to be adjusted the oral

7:40

gastric tube needs to be removed completely and

7:43

replaced the endotracho tube can

7:46

probably just do with the retraction of about three centimeters to

7:49

be an optimal positioning and then the patient should be reimaged

7:52

to make sure that everything is fine. And we do have that

7:55

follow-up examination and here we can see that the

7:58

oral gastric tube has been removed. So it's

8:01

no longer sitting in the field. The corona is here and

8:04

the tip of the endotracheal tube is here. So that's now adequately

8:07

placed and we can better see that that pneumothorax is

8:10

actually real and so now

8:13

Going to be managing a different issue, which is this pneumothorax that

8:16

was secondary to actrogenically placed oral

8:19

gastric tube into the lung and through

8:22

the pleura they'll be managing this so you'll be getting another

8:25

X-ray on this patient to see after the chest tube

8:28

gets placed at the lung is re-expanded and then they'll get the

8:31

oral gastric tube placed adequately.

8:33

But that's a conversation for another time. But here are some

8:36

examples again of what can happen when lines and tubes

8:39

are not placed adequately. I do have one other example to

8:42

share with you and this is on a CT. So

8:45

if you look at the scout view here again, lots of information on

8:48

the Scout this patient is covered in lots of

8:51

lines and tubes and what we see here are what

8:54

looks like in terms of its configuration a

8:57

swan against catheter. It doesn't

9:00

look like it's been extended distally enough to do any wedge

9:03

pressures, but it's probably sitting in the pulmonary artery.

9:06

There are a number of monitoring wires that are overlying the

9:09

patient. There's a catheter that's sitting

9:12

in the IVC along here. There's also

9:15

an ng2 that's sitting and projecting

9:18

over the stomach the patient may be

9:21

intubated as well. And so a lot of that stuff is

9:24

hard to see with the great overlap, but the CT will

9:27

help us sort this out. So really we'll go

9:30

through really quickly where our lines and tubes are located and look

9:33

for

9:33

Complications some of the other findings that we're not

9:36

going to spend a lot of time are and here in the right lung

9:39

field. It looks like there's an opacity and that may

9:42

be related to aspiration or pneumonia and then below the diaphragm. There's

9:45

lots of dilated small bowel Loops

9:48

that are gaseously dilated so

9:51

Let's take a look at where our lines

9:54

and tubes are now first. Just bring your attention to the endotracheal

9:57

tube.

9:59

Which from a perspective of the Carina is

10:02

adequately located. We also mentioned and observe

10:05

here the orogastric tube maintaining its

10:08

course in the esophagus.

10:11

And it moves below the diaphragm and into the stomach which is where we

10:14

want it to exist and to live.

10:17

We talked about the catheter in the IVC and

10:20

that's here.

10:22

And then let's take a look at the swan.

10:26

So we've got one other Central Phoenix catheter here, which is

10:29

coming down.

10:32

And we're following it back out.

10:36

And it kind of ends right here.

10:38

So sometimes it can be hard to kind of keep track of your lines and tubes

10:41

and so let's just be clear in terms of which ones

10:44

we're looking at. So we've got two that are coming in right here. And so

10:47

let's maybe start with the left again just to make sure that we're

10:50

looking at the correct one.

10:52

And this is the left.

10:54

the one that's more medial

10:57

Okay, and that one ends right here. So that one is the central

11:00

venous catheter that's coming from the left and that

11:03

one is kind of sitting over in this area here.

11:06

And that one is placed really in the right atrium. So

11:09

that could be pulled back a little bit to the SVC ra

11:12

right atrial juncture for

11:15

optimal placement. The one that's coming in from the right,

11:18

which is this one here is the one

11:21

that we're seeing projecting looping around into the main

11:24

pulmonary artery. So the swan gants

11:26

And that's this one right here coming through and

11:29

the thing that I'm observing in the track here is all this

11:32

gas that's sitting in the pericardium associated with

11:35

an along the line of where the swan Gantz

11:38

catheter is.

11:39

Again, lots of gas that's sitting around here and it's

11:42

sitting here in the pulmonary artery.

11:45

Now normally these do not have gas associated with

11:48

them. And so certainly they are placing this there's an opportunity

11:51

for puncture.

11:54

And so I would again make sure that this is

11:57

you know articulated to the clinical team immediately. We do

12:00

see a pericardial effusion that's beginning and when we

12:03

measure that fluid that's here.

12:05

It's not just simple fluid measuring one

12:08

or two houndsville units, but it's measuring about

12:11

less than 20 so it's not completely simple

12:14

all those low density. It's not completely heterogic but it's very concerning

12:17

given the gas and the trajectory of this line that

12:20

there's been again movement of

12:23

this catheter outside of its intended area and

12:26

that the gas is a secondary complication. So

12:29

we want to make sure that we report that there's some other findings that

12:32

you may notice in the periphery that we're not going to really talk about but

12:35

there's societies there's some gas here in the

12:38

radicals. Those are not necessary germane to our

12:41

discussion around the lines and tubes and being able to understand where

12:44

those are. There's also the Aerospace consolidation in

12:47

the right lower loan that we mentioned before

12:50

obviously want to remember to look at your soft tissues

12:53

your bones. Look at the media style structures. Look for any lymph node.

12:56

If you've given contrast which we did in this

12:59

case you want to look for any evidence of vascular abnormality. But

13:02

again, these were cases that kind of

13:05

took us through

13:06

Many things that can happen with lines and tubes that

13:09

go amiss or a rye in their intended

13:12

course, so hopefully you'll keep this in mind the next time you're looking

13:15

at lines and tubes question mark on the

13:18

requisition.

Central airways are patent. No pleural effusion or pneumothorax. Confluent areas
of peripheral consolidation in the posterior right lower lobe with central
groundglass opacity. Groundglass opacity and consolidation in the anterior right
middle lobe. Trace bilateral pleural effusions. Adjacent atelectasis in the
dependent left lower lobe.
VISIBLE ABDOMEN:

1. Foci of air present in the right atrium/atrial appendage, right ventricle and
right ventricular outflow tract. Correlate with recent
procedure/instrumentation.
2. Right middle/lower lobe peripheral consolidation could represent pulmonary
infarct, possibly due to air embolism.
3. Multistation mediastinal and supraclavicular lymphadenopathy. Nonspecific and
could be reactive in etiology.
4. Partially imaged intra-abdominal free fluid and pneumatosis intestinalis.
Please refer to the separately dictated CT of the abdomen and pelvis obtained on
