00:00
Now, sadly, there is no known cure.
00:04
It's kind of a long process but our treatment goal is to
lessen the severity and shorten the recovery time,
that's our goal, so we wanna make sure that it doesn't
progress up to respiratory paralysis,
if possible, and we want the patient to have a shorter
recovery time so they can return to their normal life
quicker.
00:24
So Guillain-Barre patients are usually admitted to critical
care units because we wanna watch them very closely.
00:31
If they are in a med-surg unit, they would be behind the
door, not visible by nurses,
you don't have the opportunity to observe your patients as
closely.
00:39
Now, a telemetry unit would be one where they have a
portable monitor, right,
but you still don't usually have direct visualization of the
patient.
00:48
In a critical care unit you have direct visualization of
your patients, they're on a cardiac monitor,
they're probably on a pulse ox especially for Guillain-Barre
and those readings will be available at the nurse's desk
and to the cardiac unit that where the text are just
monitoring cardiac rhythm.
01:07
So it's a logical place, it's a safer place to put a patient
that we're worried about having respiratory problems in the
critical care unit where they can be observed.
01:17
Now if they progress well with the treatment they may only
be there for a short time,
if we can't shorten that severity, they may end up staying
in that unit longer.
01:26
So we're looking at the treatments for Guillain-Barre.
01:29
Now, here we're gonna look at plasmapheresis versus
immunoglobulin therapy.
01:34
Let me just tell you, it's a tie.
01:37
The key point is start the treatment within two weeks of the
symptoms so within two weeks of onset of the initial
symptoms,
we need to start that treatment that was what makes it most
effective.
01:49
Is plasmapheresis more effective than immunoglobulin
therapy?
Not really. Either one is effective.
01:56
Maybe you can find that trying to mix them or one after the
other really doesn't make a significant difference,
so the health care team will decide which one is most
appropriate based on resources or your patient but both are
good.
02:10
Let's talk about what they are.
02:11
Plasmapheresis is a plasma exchange so look at the graphic
there.
02:17
You see that 55% of your blood volume is plasma, less than
1% is your white cells and platelets,
and about 45% are your red cells.
02:26
So here's what happens in plasmapheresis, they take the
blood out of the patient,
they'll removed some plasma and return just the red blood
cells.
02:36
So, the plasma is the part that contains the antibodies,
now, remember, we're having problems with the peripheral
nervous system being attacked in Guillain-Barre Syndrome.
02:45
So they'll remove the plasma and then they'll either treat
it and they'll return just the red blood cells.
02:51
Now your body will kick it up and will replace that plasma
volume.
02:55
They don't replace all of your plasma in plasmapheresis.
03:00
You'll do a series of treatments; but when that plasma is
removed,
your own body will replace those other plasma volume
otherwise,
if its problematic, you can also receive a unit of plasma
so they can give you from donors just to replace the plasma
volume if the body is not able to keep up.
03:18
So plasmapheresis, blood goes out, plasma removed, red cells
are returned,
remember, those are the oxygen carrying component.
03:28
Now they may or may not give you an additional unit of donor
plasma,
we'll just have to see how each patient progresses.
03:35
Okay, so that's plasmapheresis.
03:39
Now we're gonna talk about immunoglobulin therapy and this
is high dose immunoglobulin therapy.
03:45
These are proteins, right? Immunoglobulins are proteins that
are made in the body to attack affecting organisms.
03:52
Now we take IVIg from a large pool of donors
so they're gonna give the patient a donation from a large
pool of donors of this immunoglobulin,
so this helps the patient by lowering the effectiveness of
the nerve attacking antibodies
because now they're diluted.
04:12
We're giving you this donation from a large pool of donors
so they're now diluted with non-specific antibodies
so all the antibodies that are present in that donor pool
are now put into your patient with Guillain-Barre
that's what helps dilute the nerve attacking antibodies.
04:29
This gives antibodies a combined a harmful antibodies and it
will neutralize them.
04:34
So plasmapheresis, immunoglobulin therapy, they're both
effective.
04:39
Plasmapheresis just involves removing the blood and putting
back in the red cells getting rid of the plasma.
04:46
High dose immunoglobulin therapy requires the donation from
a large pool of donors but both work and both are effective.
