Q

what happens if you have aortic aneurysm rupture for patients that have it in retropertioneal space ? (abdomen)(3)
its a steps

A

bleeding may be tampondaed
( bleed but eventually run out of space, causes pressures on the vessel and stops the bleeding, this pressures causes severe back pain )

severe back pain

grey turners sign
( back, flank ecchymosis)

Q

what happens if you have an aortic aneurysm rupture in your thoracic or abdominal cavity ? (3)

think of the steps for this

A

massive hemorrhage causes hypoveolmic shock

patients dont survive long enough to get into the hospital

if survive, immediate resusistcitation and immediate surgery

Q

what is the interprofessional care we are going to be wanting to help patients with a small aneurysm?

A

really going to be watching for changes in size and symptoms

ultrasound checks every 6-12months

increase in physical acitivity, stop smoking, watch cholesterol levels

21
Q

what is the interprofessional care we are going to be wanting to help patients with a large aneurysm?

A

surgery

22
Q

what are the two types of surgery we can do for patients who have large aortic aneurysm ?

A

open aneurysm repair (oar)
end-vascular aneurysm respair

23
Q

describe what we are doing in open aneurysm repair for large aneurysm?

A

clamp the aorta ; proximal and distal aneurysm

put in a graft
sew in the vessels around the graft

24
Q

what is the biggest concern and risk for patients who have oar?

A

acute kidney injury
( decrease perfusion can occur from the clamping and graft )

25
Q

what is a end-vascular aneurysm repair ?
describe it

A

thred in the graft to the anerusym and hook it in place, and it will stay in place

26
Q

how does the endovascular graft procedure help the patient overtime?

A

shrink the aneurysm overtime

27
Q

post procedure from an endovascular graft, we usually like to get what done for the patient in order to check for leaks and confirm the patency of the procedure?

A

angiography

28
Q

what are the potential complications that can occur to patients after an end-vascular graft procedure?

dont overthink it, think about the graft itself in the patient and what It can cause

A

stent will migrate
thrombus
infection
dysfunction
need lifelong follow up

29
Q

in general what are some potential complications with any aneurysm repair ?

A

aneurysm growth
rupture
aortic dissection
bleeding

30
Q

what’s the most common complication after an aneurysm repair?

A

endoleak

31
Q

patients who experience the 6ps after a repair, what do we do ?

A

call the doctor and emergency surgery because they could lose their leg

32
Q

what is a really lethal complication that can occur from aneurysm repair?

A

intraabdominal hypertension

33
Q

what is intraabdominal hypertension?

A

pressure increases that puts more pressure on abdominal organs and diaphragm

34
Q

intraabdominal hypertension is often associated with what?

A

abdominal compartment syndrome

35
Q

abdominal compartment syndrome also can occur in what other disease process?

A

obtstrutive shock

36
Q

what is the treatment for patients who experience intraadbominal hypertension ? (2)

A

open surgical compression
percutaneous drainage

37
Q

nursing management
assessment

  • history and physical exam
  • watch for signs of cardiac, pulmonary, cerebral and lower extremity vascular problems
  • establish baseline data to compare postoperatively

mark pedal pulses
monitor renal function
monitor mental status & neurological function

A
38
Q

what are some clinical manifestations for aneurysm rupture?

A

diaphoresis
pallor
weakness
tachycardia
hypotension
abdominal, back or groin pain
changes in LOC
pulsating abdominal mass

39
Q

Overall goals
- Normal tissue perfusion
- Intact motor and sensory function
- No complications related to surgical repair

Thrombosis
Infection
Rupture

health promotion
- Alert for opportunities to teach health promotion to patients and their caregivers
- Encourage patient to reduce cardiovascular risk factors (Table 33-2)
- These measures help ensure graft patency after surgery

A
40
Q

preoperative TEST!!
- Patient/caregiver teaching about disease, treatment plan, and postoperative care
- Providing emotional support for patient/caregiver
- Preoperative routines
- Bowel prep
- NPO
- Shower
- IV antibiotics right before incision made

A
41
Q

ICU monitoring 24 to 48 hours
postoperative TEST!!

  • Central lines
  • Endotracheal tube and mechanical ventilation
  • Peripheral IV lines
  • Urinary catheter
  • NG tube
  • Chest tube and Lumbar drain possible
  • Continuous ECG monitoring
  • Pulse oximetry
  • Pain medication
A
42
Q

Acute care
Normal blood pressure
IV fluids and blood components
CVP or PA pressure monitoring
Urinary output monitoring - hourly
Avoid severe hypertension
Drug therapy may be indicated

ONGOING MONITORING
CV status
Infection control
GI function
Neurologic function
Peripheral perfusion
Renal function

A
43
Q

cardiovascular status
Continuous ECG monitoring
Electrolyte monitoring
Arterial blood gas monitoring
Oxygen administration
Antidysrhythmic and antihypertensive meds
Pain control
Resume heart medications

infection
Antibiotic administration
Assessment of temperature
Monitoring of WBC
Adequate nutrition
Observe surgical incision for signs of infection
Hand hygiene and aseptic technique for all invasive catheters; perineal care to  risk of UTI

GI
Monitor for paralytic ileus; bowel sounds
Passing of flatus = return of bowel function
Record amount and character of NG tube output
NPO; provide oral care
Abdominal assessment
Assess for signs of bowel ischemia—absent bowel sounds, fever, abdominal distention, diarrhea, and bloody stools

A
44
Q

neurologic status

  • Level of consciousness
  • Pupil size and response to light
  • Facial symmetry
  • Speech
  • Ability to move upper extremities
  • Quality of hand grasps
  • Descending aorta—neurovascular check to lower extremities
A
45
Q

Frequent pulse assessment —doppler, if needed

Ascending aorta and aortic arch-Carotid, radial, and temporal

Descending aorta-Femoral, popliteal, posterior tibial, and dorsalis pedis

Extremity assessment
Temperature, color, capillary refill time, sensation, and movement of extremities

Vasospasm and hypothermia can cause absence of lower extremity pulses (temporary)

Absent pulses + cool, pale, mottled, or painful extremity means embolization or graft occlusion

Report immediately

vasospasm is ____ normal

A

not!!!

46
Q

renal notes

  • Hourly urinary output (initially)
  • Accurate I & O
  • Daily weight
  • CVP pressure
  • Blood urea nitrogen/creatinine
  • Decrease renal perfusion may occur with: embolization of plaque to renal arteries, hypotension, prolonged aortic clamping or blood loss
A
47
Q

Ambulatory care

  • Encourage patient to express concerns
    Fatigue, poor appetite, irregular bowel habits, and male sexual dysfunction are common
  • Instruct patient to gradually increase activities
  • No heavy lifting for 6 weeks
  • Teach about signs and symptoms of complications
  • Infection
  • Neurovascular changes
A
48
Q

Expected outcomes
- Patent arterial graft with adequate distal perfusion

  • Adequate urine output
  • No signs of infection
A
49
Q

something I just want to emphasize that I feel like might be on the test, we want patients to gradually increase acitivyt but avoid heavy lifting for about ___weeks

A
