Aneurysm (Dissecting, Repair) for Progressive Care Certified Nurse (PCCN)
Included In This Lesson
Outline
Aneurysm (Dissecting, Repair)
Definition/Etiology:
- Aneurysm: abnormal dilation of an artery due to a weakened vessel wall
- Types
- Thoracic vs Abdominal
- PCCN focuses on AAA
- Located just below renal arteries
- Caused by Atherosclerosis
- Risk Factors: HTN & Smoking
- Most common in men >60 years old
- Danger
- Risk for Dissection: Separation of wall layers
- Usually asymptomatic – until they are NOT
Pathophysiology:
- Aneurysm
- Inflammation and breakdown of the inside of the vessel wall
- .Weak Wall = loss of structure integrity
- Wide Wall -bulge (balloon) blowing up
- Dissection (Life Threatening)
- Tear in the artery at Tunica Intima
- Blood pools between layers
- Blood spills in up and down beside original lumen
- Cause Ischemia/Lack of Perfusion
- AVOID Rupture
- An aneurysm is a bulge in the artery that behaves like a balloon. Ever blow up a balloon?
- At first blowing it up is easy, but eventually there is more pressure, and if you continue to blow on that balloon – POP!
Noticing: Assessment & Recognizing Cues:
- Assessment: Abdominal Aortic Aneurysm Cues
- Most Individuals are asymptomatic
- Observe: Pulsatile abdominal mass lower abdomen (left of midline)
- Usually non-tender on palpation
- Vague, nonspecific abdominal pain
- Advanced Auscultation: Bruits below renal arteries
- Assessment: Dissection Subjective Cues
- PAIN
- Unrelenting lower back pain (flank)
- “Sudden, tearing, ripping”
- Unrelenting lower back pain (flank)
- Anxiety
- PAIN
- Assessment: Dissection Objective Cues
- Signs/Symptoms of Hypovolemic shock
- ↑Resp ↑Pulse (Weak)
- ↓BP
- Narrow pulse pressure
- Normal 30-40 mmHg
- Signs/Symptoms of Hypovolemic shock
Interpreting: Analyzing & Planning:
- Interpreting: Labs
- CBC – H/H for anemia/hemorrhage
- ↑ BUN/Creatinine – Kidney involvement
- Interpreting:Diagnostics
- Ultrasound
- Non-specific abdominal pain = Find AAA accidently
- CT
- Know patient has a AAA
- Gold Standard for stable patient
- Surgery planning
- TEE
- Intra-Operative (Plan as we go)
- Patient is Unstable
- Rupture (CCRN material)
- Ultrasound
Responding: Patient Interventions & Taking Action:
- General
- ABCs
- Pain management
- Prepare Patient for surgical intervention
- Pharmacological Interventions
- Beta Blockers – Lower BP/Lower
- ASA – Once Dissection is fixed – ischemia
- Statins – Lower Inflammation
- Non-Pharmacological Interventions
- Establish IV access
- ECG/Telemetry
- Medical Management
- AAA over 5.5cm -Endovascular Stent
- Dissection –Emergent Surgery
Reflecting: Evaluating Patient Outcomes:
- Wean from Vent (surgery)
- Monitor airway
- Monitor for bleeding
- ↓BP
- ↓Pulses
- Monitor Urine Output
- Monitor BUN & Creatinine
- Pain Management
Linchpins (Key Points):
- Notice
- Interpret
- Respond
- Reflect
