00:01
Now we talked about medications
to treat inflammation,
glucocorticoids are things our body
normally produces by the adrenal cortex.
00:09
They've got a really cool
picture for you there.
00:12
See the adrenal gland just kinda
snug right on top of the kidneys.
00:15
It's not part of the kidneys
but that's where it lives
so normally your body produces
glucocorticoids from the adrenal cortex.
00:25
The adrenal gland has a medulla and a
cortex but that's really easy to remember
because I want you to underline
the letters, C-O-R-T, cort
and that will help you remember that
this comes from the adrenal CORTex.
00:42
Now we can give these medications
as inhalers, oral pills or by IV
So the best route if we're dealing with
respiratory is to get them inhaled
because these drugs come
with some side effects.
00:57
As you progress and take an
oral medication or an IV,
your body's gonna have more systemic effects of
glucocorticoids and we'll talk about this in just a minute.
01:08
Again, NOT rescue medications.
01:11
These are ones that we use after. we've
given if we're in an acute attack,
we'll use these after we've given those.
01:18
So if I have an exam question asking you which
medication was it important to give first?
the short acting beta-2
adrenergic agonist first,
the inflammatory meds whichever one
they've chosen are given next.
01:30
Okay we give these on a fixed schedule,
Remember my friend that I've
talke to you about, right.
01:36
you don't take it PRN (pro re
nata), as you think you need it,
these have to be given on a fixed schedule
so they control that inflammation.
01:45
Once the inflammation process
has already started,
it's a lot harder to get those horses
back into the barn as they say
so that's why you want
them to take it everyday.
01:54
They might just take it seasonally
if they have seasonal allergens
that are irritating their asthma
or their respiratory problems
But some people take these
year-round, 365 days a year.
02:06
They suppress inflammation and
that's definitely what we want.
02:10
It helps both our COPD patients,
and our asthmatic patients.
02:14
In fact as we roll through these, you'll see
that we use a lot of the same medications
to treat both asthma and COPD.
02:21
So looking back at this one, glucocorticoids
are medications we give that mimic
what my adrenal cortex
does naturally in my body.
02:31
We can get it inhaled which is the
best if we want to limit side effects,
Oral, now you're gonna have
systemic side effects or IV.
02:39
We use it to prevent attacks,
we give it on a fixed schedule.
02:42
It could help both our COPD
and our asthma patients.
02:46
Now when I have glucocorticoids on board
because they suppress inflammation,
I have less of those nasty
mediators released.
02:54
Remember those leukotrienes,
histamines, prostaglandins.
02:59
When those guys are running loose in my
body and they connect with their receptors,
I have that horrible side effects and all
that inflammation that I don't want to have.
03:08
So when the glucocorticoids are consistently
present, give them on a fixed schedule.
03:14
I'm gonna have less edema in the
airway mucosa, that's cool.
03:18
Less edema means more open airways.
03:21
Remember that picture where you saw the difference
in those swollen airways and open airways?
That's what I'm looking for.
03:27
So a fixed dose of glucocorticoids
on board,
I'm gonna have less edema in the airway
mucosa, fewer inflammatory responders
like the neutrophils, and the leukocytes
running around and wreaking havoc.
03:40
So as long as I keep it in my body
consistently in the times when I'm exposed,
I'm gonna have a much easier
time breathing.
03:49
Now to minimize those glucocorticoid effects, you wanna
be really careful of what we're giving in our patients,
You want them on the smallest dose for the shortest
period of time for the least systemic route.
04:01
That's why inhaled is always
our first choice if we can
and as we progress to oral or IV, you're
gonna have systemic side effects.
04:09
The higer the dose of the patient's on, the
longer the time they are on that dose,
you're gonna have more systemic effects and
a risk of suppressing that adrenal gland.
04:20
Now we'll go into glucocorticoids in more detail
in a special video just on glucocorticoids
but for now, I want to
introduce you to that concept.
04:29
Okay so the adrenal gland normally
puts out glucocorticoids.
04:33
When I give a patient glucocorticoids
inhaled, via pill or IV,
now I'm filling the body
with extra substances.
04:44
So the adrenal gland isn't really stimulated
to put out its own corticosteroids
and it will become kinda lazy.
04:51
That's really what suppressed means.
04:53
So the higher the dose, the
longer you're on glucocorticoids,
the bigger the risk for
adrenal gland suppression.
05:01
Inhaled?
Not as big a risk.
05:03
Oral?
Yeah, now we've got a risk.
05:05
And IV? Of course we've
got an even bigger risk.
05:08
And the longer period of time
the patient is on higher doses,
then the more risk there is for
adrenal gland suppression.
05:16
So, glucocorticoids adverse effects kinda look
like the same effects as Cushing's disease.
05:23
We call it Cushing's Syndrome.
05:26
Okay, now I want to take a look at the glucocorticoids
adverse effects because they're significant.
05:32
So we'll talk about this believe it or not in
even more detail in our corticosteroid video
but you need to understand this for
patients that have respiratory problems
because we use the glucocorticoids
to suppress inflammation.
05:45
Now I'm gonna do something a
little different with you
and I know you're not gonna like it, I'm so okay
with that but I want you to put your pencil down
That's it, let go of the pencil or the
pen, set it down for just a second.
06:00
Okay, all right, now we're ready.
06:02
So I want you to use your
hand and do this with me.
06:05
So "moon face" got it?
moon face, facial hair,
mood swings, buffalo hump.
06:15
Okay, try it again with me - moon face,
facial hair, mood swings, buffalo hump.
06:24
Okay, those are the first ones
that I want you to think about.
06:28
If I have a patient that's on glucocorticoids,
higher the dose, longer the time you're having it,
these are the side effects
that they're going to have.
06:38
They're gonna look like somebody
who has Cushing's disease,
but really it's just Cushing's
Syndrome because we did it to them.
06:44
In Cushing's disease, that adrenal cortex just
go crazy and pushes out all these hormones.
06:50
In Cushing's syndrome, we are putting more medications
into the patient that mimic that disease.
06:56
So we're putting in corticosteroids.
06:59
So moon face,
don't write anything down yet.
07:02
Moon face, got it?
Super full face - they look like that, not because
they're gaining so much weight, although they will,
but their face just becomes
really really full.
07:14
We'll be walking through them all and you can pick
out people that you know are on costricosteroids.
07:18
Facial hair.
07:19
Hey if you're a guy,
not that big a deal.
07:22
If you're a girl like me,
this is a big deal.
07:26
Nobody wants to be seen as
the bearded lady, right?
So we've got... stay with me,
don't write anything down yet.
07:32
Moon face, facial hair,
mood swings, buffalo hump
Now last two, mood swings?
Wow! this can make you just wow, irritable,
angry, cry, teary, doesn't matter,
really messes with your moods.
07:51
And the buffalo hump, back here?
That's the accumulation of fat right in
the middle of your back in the back.
07:59
And that's why we call it a buffalo hump
because it makes you look like a buffalo.
08:03
So, stay with me, resist the urge
to write things down right now
because the goal is that you
get your body engaged,
this will help you take a break
and help it encode better.
08:14
Moon face, facial hair,
mood swings, buffalo hump.
08:18
Good, alright now, we've done all the things
up here, let's move down to cardiovascular.
08:24
There's a potential for increased fluids
because we'll talk about this in more detail
but just trust me on it now, some of the
corticosteroids include aldosterone, right?
And we have aldosterone that tells
your body to hang on to sodium.
08:40
and wherever sodium goes,
water follows.
08:43
So you have potential for
increased fluids,
which means that your blood pressure
will likely be a little elevated
because I have more volume, I
have a higher blood pressure.
08:54
Changing fat distribution, we already
talked about the buffalo hump in the back
but these people put weight
on right in the middle.
09:02
Again, not something anyone has, sometimes
they just put weight right around the middle
so they'll look kinda like a martini
olive on little toothpick when they do that.
09:13
They've got this big fat
distribution in the middle.
09:15
It can also be really hard on
their bones and their skin.
09:18
So stay with me, we'll
restart from the beginning.
09:21
Moon face, facial hair,
mood swings, buffalo hump.
09:26
They've got cardiovascular, increased
fluids, changing fat distribution,
they put it on right
around the middle.
09:32
It's really hard on their bones and their
skin, and it suppresses growth in children.
09:39
So we want to give the tiniest bit
that can be effective for children
because we don't want to
suppress their growth
Okay, those are the major side effects that
you need to be aware of in glucocorticoids.
09:51
I promise we'll go over it again in our other video
but you need to know this for the respiratory videos,
that these are the things that
patients would experience.
09:59
Now what I want you to think about is, how
would we write an online dating profile
for somebody who has moon face, facial hair,
mood swings, buffalo hump, increased fluids,
fat distribution, really hard on their bones and skin and
they're gonna be really really short if they're a kid.
10:19
So we'll look at that more in the
endocrine drug presentation,
but that's a good review for you to know that even
my patients who don't have an endocrine problem,
they have a respiratory problem, we
put them on these corticosteroids.
10:31
Watch that adrenal gland,
educate your patient
that, hey if they start noticing
these things about themselves:
their face becoming fuller, facial hair, they're having
a hard time monitoring and mediating their moods,
we would expect that.
