Q

What things make an Aneurysm so deadly?

A

The sluggish blood flow within the aneurysm may cause a blood clot and they can become Emboli and travel.

They may Rupture with Hemorrhage and Hypovolemic Shock.

A

Often asymptomatic

Deep, diffuse chest pain or angina + Pulsating mass in periumbilical area to left of midline + Bruit over mass + Mid-abdominal or lower back pain (due to aneurysm compression) + Patient states can feel his or her heart beating

Q

After an Acute Rupture, what is the mortality rate?

A

90%

22
Q

When a pt with an AAA starts complaining of a Searing, Ripping Pain in their abdomen or retrosternal area, it is a sign of-

A

Impending Rupture

23
Q

What are the surgeries that can be used for an AAA?

A

Conventional
Endovascular Graft

24
Q

What is Grey Turner’s Sign?

A

Ecchymosis (Bruising) on the Flanks

25
Q

What is Grey Turner’s Sign an indicator of?

A

Never normal, indicates some type of abdominal bleed. Can be caused by an AAA

26
Q

Signs of a slow leak of an Aneurysm =

A

Pallor + Weak + Increasing HR & Pulse + Dropping BP + Decreased LOC + Diaphoresis

27
Q

Signs of Hypovolemic Shock caused by abdominal bleeding =

A

Hypotension + High Pulse + Pallor + Clammy Skin + Oliguria + Altered LOC + Abdominal Tenderness

28
Q

When conservatively treating an AAA, how often should the pt have their Aneurysm size monitored? What would you use?

A

Every 6 Months to Annually
(Use CT, MRI, Ultrasound)

29
Q

What is done during Conventional Surgery to treat an AAA?

A

Incise area, remove plaque, insert graft, sew original walls around graft

30
Q

What is done during a Endovascular Graft?

A

Minimally invasive.

Femoral cut down, graft (Enclosed in a sheath) is inserted and advanced to aneurysm area. Once at proper spot, it’s deployed and opens. The blood now flows through this

31
Q

What are some post-operative nursing interventions after an Aortic Aneurysm Repair is done on a pt?

A

Graft Patency:
Monitor CVP readings or PA pressures hourly
IV Diuretics- Furosemide
IV Antihypertensives- sodium nitroprusside, metoprolol, hydralazine labetalol

Renal Perfusion:
Accurate I&O; Urine output hourly
Daily BUN/creatinine
Daily weights

Infection:
Broad Spectrum Antibiotics
Assess temp and WBC

CV Status:
Continuous ECG monitoring
Frequent electrolytes and ABGs
Oxygen
IV antidysrhythmic meds and antihypertensives
Adequate pain control
Resumption of heart meds

GI Status:
NG tube to LWS
Assess bowel sounds
Neurological status
Peripheral perfusion
Check all pulses
Note color, temperature, capillary refill, sensation and movement of extremities

32
Q

What does it mean if a pt’s graft patency is too high?

A

Stress on Anastomoses, causes leaking or rupture

33
Q

What does it mean if a pt’s graft patency is too low?

A

Graft Thrombosis

34
Q

What’s some pt education for a pt who got treated for an AAA?

A

No heavy lifting for 6 weeks.

Report redness, swelling, increased pain, temp >100, & drainage from incisions.

Teach patient how to monitor peripheral pulses and to report changes in color/warmth.

Sexual dysfunction…urologist referral if erectile dysfunction.

35
Q

What’s an Aortic Dissection?

A

Tear in innermost lining of arterial wall of aorta

36
Q

Risk factors for an Aortic Dissection?

A

Hypertension, male gender, advancing age, pregnancy, Marfan syndrome, blunt trauma, congenital heart disease, cocaine or methamphetamine use, history of cardiac surgery, atherosclerosis

37
Q

Symptoms of an Aortic Dissection?

A

Sudden severe angina or back pain, often described as a ripping or tearing sensation + syncope, dizziness, weakness

38
Q

Is an Aortic Dissection life threatening?

A

Yes

39
Q

What’s the most common cause of an Aortic Dissection?

A

Chronic Hypertension

40
Q

Complications of an Aortic Dissection =

A

Cardiac Tamponade (If blood enters the Pericardial Sac) + Dissected area weak and prone to rupture

41
Q

An Aortic Dissection is diagnosed the same way a AAA is.
True or false?

A

True

42
Q

An Aortic Dissection will be treated conservatively if-

A

No Severe Complications

43
Q

What is some conservative treatment for an Aortic Dissection?

A

Lower BP + Decrease myocardial contractility + Treat pain + Bed rest

44
Q

What is the standard treatment for surgery on an Aortic Dissection?

A

Endovascular Surgery

45
Q

Symptoms of Cardiac Tamponade =

A

Hypotension + Narrowed Pulse Pressure + JVD + Muffled Heart Sounds + Pulsus Pardoxus

46
Q

What is Pulsus Paradoxus?

A

Abnormally large decrease in SBP during inspiration

47
Q

If an acute descending aorta dissection occurs, what’s a must?

A

Emergency Surgery

48
Q

Beta blockers can be used to decrease-

A

Contractility

49
Q

Calcium beta blockers can be used to decrease-

A

BP

50
Q

How low do you want a pt’s BP to be if they’ve got an Aortic Dissection?

A

As low as possible while still keeping the organs perfused

51
Q

Following an aortic aneurysm repair, for which complication is most important should the nurse monitor the patient?
A.) Infection
B.) Bleeding from the graft site
C.) Prolonged surgical hypothermia
D.) Dislodged thrombi
