Q

Pathology of Peripheral Vascular Disorders

A

Pump failure = inadequate peripheral blood flow
* Heart Failure with reduced ejection fraction (HFrEF or systolic HF)
* Causes accumulation of blood in the lungs, reduced CO, and inadequate arterial blood flow to tissues
* Heart Failure with preserved ejection fraction (HFpEF or diastolic HF)
* Causes systemic venous congestion and reduced CO

Alterations in blood and lymphatic vessels (reducing flow)
* Arterial - damage or blockage to vessels by atherosclerotic plaque, thromboembolus, infection or inflammatory process, etc.
* Venous – thromboembolus obstructing vein, incompetent venous valves, or reduced effectiveness of surrounding muscles
* Lymphatic – tumor, damage from mechanical trauma, or inflammatory process

Circulatory insufficiency of the extremities
* Most disorders results in ischemia and produces symptoms of pain, skin changes, diminished pulses, and possible edema

Intermittent Claudication

A

Q

What is known as the hallmark symptom of PAD?

A

Intermittent claudication

90
Q

As the tissues are forced to complete the energy cycle w/out adequate nutrients & O2…

A

…muscle metabolites & lactic acid are produced

-Muscle metabolites aggravate nerve endings-> causes pain

91
Q

Approximately what percentage of the arterial lumen must be obstructed before intermittent claudication is experienced?

A

~50% of the arterial lumen or 75% of the cross-sectional area must be obstructed

92
Q

What helps alleviate intermittent claudication pain?

A

Rest (decreases metabolic needs of muscles)

93
Q

Rest Pain

A

Persistent pain in the foot or digits when the patient is resting

94
Q

What does the presence of rest pain indicate?

A

Rest pain indicates a severe degree of arterial insufficiency & critical state of ischemia

95
Q

What can be done to increase perfusion to distal tissues in the presence of rest pain?

A

Lowering the extremity to a dependent position

96
Q

How can the site of arterial disease be deduced from the location of claudication?

A

It can be deduced because pain occurs in muscle groups distal to the diseased vessel

97
Q

If the patient is experiencing calf pain, where would the site of claudication be?

A

Insufficient blood flow through either the superficial or popliteal artery

98
Q

Rubor

A

Reddish-blue discoloration of the extremities
-May be observed w/in 20secs-2mins after extremity is placed in dependent position

99
Q

Cyanosis

A

Bluish tint of the skin that is manifested when amount of oxygenated hemoglobin contained in the blood is reduced

100
Q

Nursing Considerations for Pulse Palpation

A

Palpation is subjective

Use light touch & more than just the index finger for palpation (strongest pulse) to avoid mistaking their own pulse for the pt’s pulse
-Same for thumb

Occlusive arterial diseases impairs blood flow & can reduce/obliterate palpable pulses in the extremities

Palpate bilaterally & simultaneously
Symmetry in:
-Rate
-Rhythm
-Quality

101
Q

Handheld Continuous Wave (CW) Doppler Ultrasound

A

Used to detect blood flow when pulses cannot be reliably palpated

102
Q

What determines at what depth where blood flow can be detected by a Doppler?

A

The frequency it produces
-The lower the frequency, the deeper the tissue penetration

103
Q

Nursing Considerations for Doppler Ultrasound Flow Studies

A

Place the pt in supine position, elevate HOB 20 to 30 degrees to evaluate the lower extremities
-Externally rotate the legs, if possible, to permit access to medial malleolus

Apply acoustic water soluble gel to pt’s skin

Avoid excessive pressure (severely diseased arteries can collapse w/min pressure)

104
Q

Ankle-Brachial Index (ABI)

A

Ratio of the systolic BP in the ankle to the systolic BP in the arm

105
Q

What is the ABI used to determine?

A

The ABI is used to quantify the degree of stenosis

106
Q

Steps to Determine ABI

A

1) Have patient lay in supine position for 5 mins

2) Apply appropriate-sized BP cuff to the patient’s ankle above the malleolus

3) After ID’ing an arterial signal of the posterior tibial & dorsalis pedis arteries, systolic pressures are obtained while listening to the Doppler signal for both arteries
-Diastolic pressures cannot be obtained via Doppler

107
Q

Nursing Considerations for Obtaining ABI

A

Use correctly sized BP cuffs

Document cuff sizes used

Use sufficient inflation
-Do not inflate too rapidly

Suspect medial calcific sclerosis:
- Anytime the ABI is 1.20 or greater

Lymphangitis

A

Inflammation or infection of the lymphatic
channels

210
Q

Lymphadenitis

A

Inflammation or infection of the lymph nodes

211
Q

Acute Lymphadenitis

A

Lymph nodes that are enlarged, red, and
tender

212
Q

Suppurative Lymphadenitis

A

Lymph nodes that have become necrotic
and form an abscess

213
Q

Lymphedema

A

Tissue swelling related to obstruction of lymphatic flow
-Especially marked when extremity in dependent position
-Edema initial soft and pitting; as it progresses, it becomes firm, non-pitting and unresponsive to treatment

Frequent bouts of acute infections (high fever & chills) and increased residual edema are seen with chronic swelling
* Leads to chronic fibrosis, thickening of the subcutaneous tissues, and hypertrophy of the skin
* This specific type of lymphedema is known as elephantiasis in which chronic swelling of the extremity recedes only slightly with elevation

214
Q

Primary Lymphedema

A

Congenital Malformations
- Most common
-Usually seen in women

215
Q

Secondary Lymphedema

A

Acquired obstruction
-Axillary node dissection (breast cancer)
-Leg in association w/ varicose veins or chronic thrombophlebitis
-> Usually caused by chronic lymphangitis

216
Q

Lymphedema Treatment Goal

A

Goal of therapy is to reduce and control edema and prevent infection

217
Q

Medical Management of Lymphedema

A

Manual lymphatic drainage by specially trained therapists

Diuretic furosemide

Antibiotic therapy when lymphangitis or cellulitis is present for 3-7 days

Surgical management

218
Q

Nursing Management of Lymphedema

A

Constant elevation of affected extremity

Active and passive exercises

External compression devices; Custom-fitted graduated compression stockings or sleeves

Monitor for complications:
* Flap necrosis
* Hematoma
* Abscess under the flap
* Cellulitis

Patient/Family Education
* Inspect dressing daily
* Report any inflammation or unusual dressing
* Expected loss of sensation in surgical area
* Avoid use of heating pads or exposure to sun
* Skin care

219
Q

Cellulitis

A

Occurs when a microbe enters through broken skin and release their toxins in the subcutaneous tissues, typically, staph or strep

220
Q

Clinical Manifestations of Cellulitis

A

Localized swelling or redness, warmth and pain frequently associated with systemic symptoms fever, chills, and sweating
* Redness may not be uniform; develops a pitting “orange-peel” appearance

221
Q

Nursing Management of Cellulitis

A

Treat with oral or IV antibiotics based on severity

Elevate affected area 3-6 inches above heart level
* Warm, moist packs to site every 2 to 4 hours
* Patients with sensory/circulatory deficits should use caution to avoid
burns
* Educate regarding prevention of recurrence
* Reinforce education about skin and foot care
