AAA: Pathophysiology
•
An abdominal aortic aneurysm is an
abnormal dilation of the wall of the
abdominal aorta. The aneurysm usually
develops in the segment of the vessel that is
between the renal arteries and the iliac
branches of the aorta. The most common
cause of an abdominal aortic aneurysm is
atherosclerosis. The plaque that forms on
the wall of the artery causes degenerative
changes in the medial layer of the vessel.
These changes lead to loss of elasticity,
weakening, and eventual dilation of the
affected segment. Some other causes of
abdominal aortic aneurysm include
inflammation (arteritis), trauma, infection,
congenital abnormalities of the vessel, and
connective tissue disorders that cause
vessel wall weakness.
Ulrich & Canale: (2006)
Nursing Care Planning Guides:
For Adults in Acute, Extended, and Home Care Settings, 6th
Edition7.0
Block
•
•
Most abdominal aortic aneurysms are
asymptomatic and are discovered during a
routine physical examination (signs include
palpation of a pulsatile mass in the abdomen
and/or auscultation of a bruit over the
abdominal aorta) or during a review of x-ray
results of the abdomen or lower spine. The
presence of symptoms such as mild to
severe abdominal, lumbar, or flank pain
and/or lower extremity arterial insufficiency
is usually indicative of a large aneurysm that
is exerting pressure on surrounding tissues
or an aneurysm that is leaking.
Surgical repair of an aneurysm is usually
performed if the aneurysm is growing rapidly
and/or reaches a size of 5-6 cm or larger or
if the client experiences symptoms. The
procedure often involves the use of a
synthetic graft, which is inserted to replace
or support the weakened vessel.
Module 2.2
NURSING DIAGNOSIS: Fear/Anxiety
related to:
•
•
•
•
•
•
1. unfamiliar environment and
separation from significant
others;
2. lack of understanding of
diagnostic tests, surgical
procedure, and postoperative
care;
3. anticipated loss of control
associated with effects of
anesthesia;
4. risk of disease if blood
transfusions are necessary;
5. anticipated postoperative
discomfort and potential
change in sexual functioning;
6. possibility of death.
Block 7.0
•
Desired Outcome
The client will experience a reduction
in fear and anxiety
Nursing Actions and Selected
Purposes/Rationales
1. Preoperative Care Plan, for measures related to
the assessment and reduction of fear and anxiety.
2. Implement additional measures to reduce fear
and anxiety:
a. orient client to critical care unit if appropriate
b. describe and explain the rationale for
equipment and tubes that may be present
postoperatively (e.g., cardiac monitor, ventilator,
intravenous and intra-arterial lines, nasogastric
tube, urinary catheter)
c. explain that B/P may be taken in both arms
and thighs in order to better evaluate circulatory
status
d. reinforce physician's explanations and clarify
misconceptions client has about effects of the
surgery on sexual functioning (impotence can result
from diminished blood flow in the mesenteric or
internal iliac arteries during or after surgery and/or
from nerve damage during surgery).
Module 2.2
COLLABORATIVE DIAGNOSIS:
Potential complication: hypovolemic shock
R/T related to excessive blood loss if the
aneurysm ruptures.
• Desired Outcome:
The client will not
develop hypovolemic
shock as evidenced
by:
1. usual mental status
2. stable vital signs
3. skin warm and usual color
4. palpable peripheral pulses
5. urine output at least 30
ml/hour.
Block 7.0
• NURSING ACTIONS:
• (next page)
Module 2.2
Nursing Actions and Selected Purposes/Rationales
•
1. Assess for and immediately report
signs and symptoms of conditions that
indicate impending aneurysm rupture:
•
A. Leaking aneurysm:
a. increasing abdominal girth
b. ecchymosis of flank area or perineum
c. frank or occult gastrointestinal bleeding
(occurs if the aneurysm ruptures into the
duodenum)
d. decreasing RBC, Hct, and Hgb levels
e. new or increased reports of lumbar, flank,
abdominal, pelvic, or groin pain (accumulation of
blood in the peritoneum and/or retroperitoneal
spaces causes irritation of and pressure on the
tissues and nerves)
f. diminishing or absent peripheral pulses
g. further decline in thigh B/P as compared with
B/P in arm (thigh B/P is usually slightly lower than
B/P in arm of a client with an abdominal aortic
aneurysm)
Block 7.0
•
B..Expanding aneurysm:
a. new or increased reports of lumbar, flank, or
groin pain (results from pressure on lumbar nerves)
b. increased size of pulsating mass in abdomen
c. increasing sense of abdominal and/or gastric
fullness (results from pressure on duodenum)
d. decreasing motor or sensory function of lower
extremities (results from pressure on lumbar and/or
sacral nerves).
•
C. Assess for and report signs and symptoms
of hypovolemic shock:
a. restlessness, agitation, confusion, or other
change in mental status
b. significant decrease in B/P
c. postural hypotension
d. rapid, weak pulse
e. rapid respirations
f. cool skin
g. pallor, cyanosis
h. diminished or absent peripheral pulses
i. urine output less than 30 ml/hour.
Module 2.2
•
D. Implement measures to decrease risk of
aneurysm rupture:
a. instruct client to avoid elevating legs when in
bed, using knee gatch, and crossing legs in order to
prevent restriction of blood flow to the lower
extremities and subsequent increase in vascular
pressure at the aneurysm site
b. perform actions to prevent an increase in
blood pressure:
c. limit client's activity as ordered
d. nstruct client to avoid activities that create a
Valsalva response (e.g., straining to have a bowel
movement, holding breath while moving up in bed,
lifting heavy objects)
Block 7.0
•
E. implement measures to reduce fear and
anxiety (see Preoperative Diagnosis 1)
•
F. administer antihypertensives if ordered to
reduce pressure in the dilated vessel.
•
G. If signs and symptoms of hypovolemic
shock occur:
•
a. place client flat in bed unless contraindicated
b. monitor vital signs frequently
c. administer oxygen as ordered
d. administer blood and/or volume expanders as
ordered (these need to be used with caution since
increased vascular pressure can extend a tear at
site of rupture)
e. prepare client for insertion of hemodynamic
monitoring devices (e.g., central venous catheter,
intra-arterial catheter) if indicated
f. prepare client for emergency surgical repair of
aneurysm if indicated.
Module 2.2
NURSING DIAGNOSIS:
Risk for imbalanced fluid and electrolytes
•
Third-spacing of fluid related to:
•
1. increased capillary permeability in
surgical area associated with the
inflammation that occurs following extensive
dissection of tissue during major abdominal
surgery
•
•
2. increased vascular hydrostatic pressure
associated with excess fluid volume if
present
3. hypoalbuminemia associated with the
escape of proteins from the vascular space
into the peritoneum (a result of increased
capillary permeability in the surgical area);
Block 7.0
•
Excess fluid volume related to:
•
1. vigorous fluid replacement
•
Fluid retention associated with:
•
1. increased secretion of antidiuretic hormone
(output of ADH is stimulated by trauma, pain, and
anesthetic agents)
2. renal insufficiency (can occur if there is
inadequate blood flow to the kidneys during or after
surgery)
3. reabsorption of third-space fluid (occurs about
the 3rd postoperative day);
•
•
•
Deficient fluid volume related to restricted oral
fluid intake before, during, and after surgery;
blood loss; and loss of fluid associated with
nasogastric tube drainage;
•
Electrolyte Imbalance: hypokalemia,
hypochloremia, and metabolic alkalosis related
to loss of electrolytes and hydrochloric acid
associated with nasogastric tube drainage.
Module 2.2
• Desired Outcome
The client will
experience resolution
of third-spacing as
evidenced by:
1. absence of ascites
2. B/P and pulse
within normal range
for client and stable
with position change.

Left Ventricular Assist Device
(LVAD)
A left ventricular assist device (LVAD) is implanted under the skin via “open heart”
surgery. It helps pump blood from the left ventricle of the heart and on to the rest of the
body. A control unit and battery pack are worn outside the body and are connected to the
LVAD through a port in the skin.
This is a typically a temporary measure while the patient is awaiting a heart transplant,
though in some cases it may be used

IABP
•
•
•
•
The IABP is a polyethylene balloon
mounted on a catheter, which is
generally inserted into the aorta
through the femoral artery in the
leg.
The balloon is guided into the
descending aorta, approximately
2 cm from the left subclavian
artery.
At the start of diastole, the balloon
inflates, augmenting coronary
perfusion.
At the beginning of systole, the
balloon deflates; blood is ejected
from the left ventricle, increasing
the cardiac output by as much as
40 percent and decreasing the left
ventricular stroke work and
myocardial oxygen requirements.

Module 2.2
•
The goal of treatment for heart
disease is to maximize cardiac
output.
•
Surgically this may be done by
improving myocardial muscle function
and blood flow through procedures
such as the traditional CABG (or via
less invasive procedures such as
MIDCAB, percutaneous
transmyocardial revascularization
[PTMR], and/or port access requiring
four small incisions under the left
breast), wrapping the latissimus dorsi
muscle around the heart, and/or repair
or replacement of defective valves.
Block 7.0
•
Of the three types of cardiac surgery—
(1) reparative (e.g., closure of atrial or
ventricular septal defect, repair of
mitral stenosis), (2) reconstructive
(e.g., CABG, reconstruction of an
incompetent valve), and (3)
substitutional (e.g., valve replacement,
cardiac transplant)—reparative

An open heart bypass surgery is
performed under general
anesthesia, which requires that
the patient be on a ventilator
during surgery.
Surgery begins with harvesting the
blood vessels that will become the
grafts. The saphenous vein in the
leg is commonly used because it
is long enough to create multiple
grafts. If the saphenous vein
cannot be used, vessels from the
arm can be used instead. The left
internal mammary artery is used
for a single graft and is taken once
the chest is opened for surgery.
Block 7.0
•
Once the saphenous vein has
been recovered, the chest is
opened by making an incision
along the sternum, or breastbone.
The surgeon then cuts the
sternum, allowing the chest cavity
to be opened, giving the surgeon
access to the heart.
• In the traditional CABG procedure,
the heart is stopped with a
potassium solution so the surgeon
is not attempting to work on a
moving vessel, and the blood is
circulated by a heart-lung
machine. At this time the heartlung machine does the work of the
heart and the lungs, and the
Module 2.2
ventilator is not used.
•
•
The surgeon places the grafts,
either rerouting blood around the
blockage, or removing and
replacing the blocked vessel. The
amount of time on the heart-lung
bypass machine is determined by
the speed at which the surgeon is
able to work, primarily, how many
grafts are needed.
Once the grafts are complete, the
heart is started and provides blood
and oxygen to the body. The
sternum is returned to its original
position and closed using surgical
wire, to provide strength the bone
needs to heal, and the incision is
closed.

Overview: Pericarditis
• Pericarditis - inflammation of the lining surrounding the heart (the
pericardial sac).
• Pericardial effusion - a collection of fluid in the pericardial sac. This
fluid may be produced by inflammation.
• The etiology of pericarditis in most patients is unknown, although
many diseases can cause pericarditis.
• The diagnosis of pericarditis is made by history and physical
examination including presence of a pericardial friction rub. It may
confirmed by EKG and echocardiogram.
• Pericarditis is treated with anti-inflammatory medications and by
treating any underlying disease.
• Pericardial tamponade occurs when enough fluid accumulates in the
sac to compromise the heart's ability to adequately pump blood.
• Tamponade is treated by pericardiocentesis, removing the fluid with
a needle.
Block 7.0 Module 2.2
Etiology
• Idiopathic
• The cause of the illness is not
identified (although often it's
the result of a minor viral
illness or "cold")
• Mechanical injury to the
heart
• Heart attack (myocardial
infarction) and Dressler's
syndrome
• Heart surgery and post

Module
2.2
Etiology
• Side effects of certain
medications can cause an
immune response causing an
inflammation of the pericardial
sac and pericarditis.
• Medicines that have been
implicated include phenytoin
(Dilantin), hydralazine
(Apresoline) and procainamide
(Pronestyl, Procan-SR,
Procanbid).
Block 7.0
Module 2.2
Symptoms
• Chest pain is the most
common symptom of
pericarditis.
• The pain is usually sharp and
stabbing.
• It can arise slowly or suddenly
and can radiate directly to the
back, to the neck or to the arm.
• The pain can be made worse
with deep breaths (pleuritic).
• The pain is frequently
positional and made worse
when lying flat and better when
leaning forward.
Block 7.0
• The most common physical
finding that almost always
confirms the diagnosis is a
pericardial friction rub.
Module 2.2
• Medicines that reduce
inflammation are the primary
treatment for pericarditis.
Nonsteroidal anti-inflammatory
drugs, such as ibuprofen, are
used to decrease the
inflammation and fluid
accumulation in the pericardial
sac. process.
Block 7.0
• Occasionally, a short course of
narcotic pain medication
[codeine, hydrocodone
(Vicodin) or oxycodone
(OxyContin, Roxicodone)] will
be needed.
• In recurrent cases, especially
in immunologically-mediated
causes, corticosteroids are
often very effective.
• Treatment of the underlying
cause of pericarditis is
essential and will be based on
the disease
Module 2.2
• Cardiac tamponade
• If there is enough fluid in the
pericardia sac, there may be
enough pressure on the
outside of the heart to prevent
it from beating adequately to
push blood to the body and
lungs.
• The pressure within the sac
itself needs to be higher than
the pressure within the heart
chambers, but symptoms
gradually progress as the heart
function is compromised.
Block 7.0
• Treated by pericardiocentesis,
a procedure where a long needle
is inserted through the chest wall
into the pericardial sac and fluid
is removed.
• This relieves the pressure within
the sac and temporarily resolves
the acute emergency. A plastic
tube or catheter may be left in
the chest until the underlying
illness that cause the tamponade
is addressed and further
accumulation of fluid in the
pericardium is prevented.

Cardiac Tamponade: Most serious complication of pericarditis
Pulsus Paradoxus
Pulsus Paradoxus (PP) is an exaggeration of
the normal variation in the pulse during the
inspiratory phase of respiration, in which the pulse
becomes weaker as one inhales and stronger as
one exhales.
It is a sign that is indicative of several
conditions including cardiac tamponade, pericarditis,
chronic sleep apnea, croup, and obstructive lung
disease
