How do we diagnose sickle cell anemia?
Well genetic counselling is available for parents
known to have sickle cell disease or trait.
00:09
Diagnosis of sickle cell anemia is also done as part
of the routine newborn screening done in most states.
00:16
There are benefits to early diagnosis.
00:18
These patients can have
prevention and relief of pain episodes.
00:22
You can try to prevent infections,
organ damage and strokes.
00:27
You can try to treat anemia
and control complications
and these patients can be offered
counselling, prophylaxis, increased immunizations
and follow-up information regarding research.
00:40
Managing a patient with
sickle cell disease is complex.
00:43
The patient may need the bed rest
during an acute vaso-occlusive crisis
and increased fluid therapy - this is key.
00:50
Yyour patient may need one and a half or
two times their normal maintenance.
00:54
A blood transfusion of packed red cells
can help in the setting of severe anemia
and analgesics are used to relieve pain.
01:01
There should be a really low threshold in treating a
patient with sickle cell anemia who has an infection.
01:07
Antibiotics are usually started early as the
patient's immune system is already compromised.
01:13
A splenectomy is the surgical removal of the spleen and this
is done in order to prevent recurrence of certain complications.
01:19
Your patient may need supplemental oxygen
and this oxygen is gonna be administered
because remember the red blood cells
already have dysfunctional hemoglobin
and this makes a decreased
oxygen carrying capacity.
01:30
Supplemental oxygen can help
manage the hypoxia and crisis symptoms.
01:36
To help prevent a crisis, patients are
gonna want to try to avoid infections.
01:41
They're also going to want to decrease their exposure
to cold because of the vasoactivity that happens.
01:47
Same thing goes with stress.
01:50
Patients are gonna want to be non smokers
and they want to avoid becoming dehydrated.
01:56
You'll have a really low threshold for
rehydrating a patient with sickle cell disease.
02:01
A patients with sickle cell disease can
go into a crisis in a hypoxic environment
so they're gonna avoid going to high
altitude areas or maybe climbing tall mountains.
02:12
Patients with sickle cell anemia can also prevent
a crisis by taking prophylactic antibiotics.
02:17
All children's sickle cell disease you should
take a penicillin twice a day until at least age 5
to prevent pneumococcal sepsis.
02:25
You want to be sure your patients with sickle
cell disease are up-to-date on their vaccinations
and this decreases the likelihood that
they'll get these vaccine-preventable diseases
including influenza and pneumococcal.
02:36
Children with severe types of sickle cell disease
should be offered primary stroke prevention
with annual transcranial Doppler scans
and blood transfusions when resources allow.
02:47
Hydroxyurea is a medication, it's a myelosuppressive
agent that's the only effective drug
proven to reduce the
frequency of painful episodes.
02:55
It raises the hemoglobin level and decreases
the rate of painful episodes by about 50%
Education is key in preventing a
crisis as this is a lifelong chronic disorder.
