ABDOMINAL AORTIC ANEURYSM CASE STUDY


Updated 4/24

Dear nurses,

Dear nurses.com is no longer available. Please click on the 
link : Abdominal Aortic Aneurysm
for more updated information.

An aneurysm or bulge may occur in the wall of a blood
vessel like the aorta. The abdominal aorta describes that
part of the aorta that passes through the abdominal area.
Rupture of an abdominal aneurysm carries a high mortality
rate.

CEREBRAL ANEURYSM


Updated 2/25

Scenario: Bob went to the gym and pumped iron.
Shortly after, he started to have "an explosive 
headache".

He sought medical intervention. A CAT scan 
would reveal a cerebral aneurysm.
Bob's story continues : Here


TREATMENT OF CEREBRAL ANEURYSM



A cerebral aneurysm may be repaired by clipping or embolization. Embolization is done in X Ray under fluroscopy. Platinum coils are threaded through a catheter in the groin and the aneurysm is filled. Wide necks may be difficult to coil.

What is an aneurysm?
An aneurysm is a bulge or balloon in the wall of a blood vessel.
The majority of aortic aneurysms occur in the abdominal area,
but may also occur anywhere along the blood vessels that divide
after leaving  the abdominal aorta.

For more helpful information , just click on the link:


The brain is protected by the skull. Injury to the brain may
result in swelling. 
The skull is made of solid bone and the
brain has no room to expand when swelling 
occurs. 

ICP Monitoring is done to reduce swelling and monitor
brain pressures.
The brain injured patient is at risk for
 seizures. This should be reflected in the
plan of care. Learn more, by watching the videos:

RENAL FAILURE CAUSED BY LIVER FAILURE

Updated 6/24 
Dearnurses.com is no longer available.

If the kidneys fail, hemodialysis is ordered by the doctor, in 
an attempt to remove waste products. Depending on the situation,
this may be short or long term.






Scenario: Mr.O who was in liver failure and became oliguric. Renal failure very commonly accompanies liver failure. Renal transplant may be necessary. When the kidneys have failed beyond recovery, kidney transplant is often considered.

In the meantime, hemodialysis becomes necessary, to rid the body of waste products.
Helpful hints :
- Carefully monitor and document the urinary output.
- Monitor and document the neurological status, as some patients may become confused while awaiting hemodialysis.
- Follow your institution's policies and MD orders for treatment of your patient.

SIMPLIFYING RENAL FAILURE

Updated 10/25

THE KIDNEYS ( an overview)
The kidneys are two bean shaped organs located in the
abdominal cavity on either side of the spine. They work
to filter out waste products from the blood.

Learn more by clicking on the link: Hemodialysis

Renal failure may be acute or chronic. The image 
above explains the types of renal failure.



Anasarca and its causes

Anasarca, which is also known as generalised edema, may
be caused by a number of conditions. These include:
- Heart, renal or liver failure
- Low albumin (hypoalbuminemia), burns
- Corticosteroids and more

In the above image, Mrs. had surgical intervention for a hip
fracture. She will be confined to bed for some time. Preventing 
pneumonia, DVT and skin breakdown will be included in
the plan of care.
Physical therapy will also be ordered by the doctor.

KIDNEY FUNCTION

Updated 7/24

The kidneys and their function

Typically , each human being has two kidneys. They are two bean
shaped organs situated in the flank area. The kidneys filter waste
from the blood , which is excreted as urine. The bladder acts as a
reservoir for urine.

Failure of the kidneys to do their normal function is very distressing
to the patient. Patients may become confused because of the retained
waste products. Pruritis ( itching) is also common.
Urinary output in renal may be absent ( anuria) or low (oliguria).

Causes of renal failure:

Hypovolemia  , excessive volume depletion from vomiting , diarrhea, 
blood loss or diuretics result in decreased blood flow to the kidneys
and are reversible by correction of the problem.
Drug induced renal failure may or may not be reversible.

RENAL FAILURE SIMPLIFIED


When the kidneys are no longer able to perform their normal
functions, renal failure occurs. This may be acute or chronic.
Hemodialysis and peritoneal dialysis are both used to treat
this problem. Kidney transplantation is sometimes necessary.

Failure of the kidneys to do their normal function is very
distressing to the patient. Patients may become confused 
because of the retained waste products. Pruritis ( itching)
is also common. Urinary output in renal failure may be 
absent ( anuria) or low (oliguria).

Causes of renal failure

Hypovolemia - excessive volume depletion from vomiting ,
 diarrhea, blood loss or diuretics result in decreased blood
flow to the kidneys and are reversible by correction of the
problem.

Drug induced renal failure may or may not be reversible,
antibiotics, contrast material used in radiographic studies,
 anti- inflammatory drugs may all be causes of renal failure. 

Monitoring of lab values for certain drugs like Gentamicin
will be an indicator of when levels are becoming toxic.

 Dopamine infusion which is used to increase blood pressure,
 may result in decreased urinary output when used in high doses.
Certain vitamin supplements may cause kidney stones.

Trauma whether blunt or penetrating , surgical procedures 
may damage the kidneys.

Anasarca and its causes

Anasarca, which is also known as generalised edema, 
may be caused by a number of conditions. These include:
- Heart, renal or liver failure
- Low albumin (hypoalbuminemia), burns
- Corticosteroids and more

HEPATIC FAILURE

Updated 10/25

In the image below, Mr. O presents the clinical 
picture of a patient in liver failure. His past history
includes 20 years of alcohol ingestion.

His liver is enlarged and abdomen distended. He is
also lethargic and has pedal edema. His urinary output
is tea - colored.

WHAT DOES PARACENTESIS MEAN?

Updated 6 /25

Hepatic encephalopathy

When the liver becomes damaged, ammonia and
other toxins cannot be removed.This may cause
toxins to cross the blood-brain barrier and cause
symptoms such as lethargy and mental confusion.

Paracentesis

The liver becomes enlarged in liver failure.
The abdomen also becomes enlarged.Patients
also have difficulty breathing. Paracentesis
is performed to remove excess fluid and make
breathing easier.

UNDERSTANDING LIVER FAILURE




Updated 6/25
Dear nurses, 

Dearnurses.net is no longer available.

The image above, is intended to help you
understand the clinical picture of a patient
in liver failure.

The liver ia a large and very complex organ with a lot
of work to do. Bile production which aids digestion,
converting ammonia into urea for excretion, coagulation
functions and more. Liver damage either acute or chronic
 is very debilitating to the patient.

Damage to the liver may have various causes.
The course of illness may be short or prolonged.

Patients who have illness due to liver damage may
 have jaundice . This is manifested by a yellow
pigmentation of the skin, sclera of the eyes and urine.

The skin is typically very dry and itchy. Liver  damage 
may also lead to kidney failure , coagulation( clotting )
problems and hepatic encephalopathy. 

As the liver loses the ability to do its normal functions ,
patients may experience bleeding problems, or become
increasingly lethargic,  which can lead to coma.
