Module 9- Wound Types (neuropathic, arterial, venous) Flashcards
wound type that is present for at least 6 weeks
chronic wounds
These are some characteristic of what type of wound
-necrotic tissue
-bioburben
-chronic inflammatory
-impaired hemodynamics
-senescent fibroblasts and keratinocyctes
-chronic wound fluid with growth inhibiting proteases
-overgrowth of epithelium with lack of underlying connective tissue
chronic wounds
What are the 4 categorize of chronic wounds
- arterial
- venous insufficiency
- neuropathic/diabetic
- pressure
name the type of wound category
-ischemia
-micro or macro vascular disease
-smoking
arterial
name the type of wound category
-deep vein thrombosis
-recent surgery, ankle fusion
-prolonged standing, pregnancy
-congestive heart failure
venous insufficiency
name the type of wound category
-diabetes
-peripheral vascular disease
-hansen’s disease
neuropathic/diabetic
-pressure/shear
-immobility, moisture
-decreased sensation
-poor nutrition
pressure
_____ wounds
-occur on the foot usually plantar surface of toes
-causes by mechanical forces or minor trauma
neuropathic wounds
Pt with ____ wounds typically have sensory, autonomic and motor neuropathies
neuropathic
____ wounds are caused by ischemia
arterial
___ wounds typically occur in the peripheral extremities
caused by macro- or microvascular disease
arterial
_____: obstruction of the larger named arteries by PAOD, embolus, thrombus, trauma
_____: disease of the small unnamed arterioles and capillaries usually associated with diabetes or small emboli
Arterial wounds
macro:
Micro:
Neuropathic wounds pain typically relieved with ambulation—T or F
true
Both neuropathic and arterial wounds occur mainly on the foot and toes T or F
true
How does the appearance of the foot differ in neuropathic and arterial injuries
neuropathic- architectural changes in the foot
arterial- normal looking foot
appearance of wounds:
pink, moist callus formation, plantar surface, skin usually warm
neuropathic
appearance of wound:
pale dry well defined margins, limb color pale, skin cool to touch
arterial
Which has a normal ABI neuropathic or arterial injuries?
neuropathic
what are the grades of the diabetic foot classification
grade 0- intact skin
grade 1- superficial ulcer
grade 2- deep ulcer
grade 3- ulcer with bone involvement
grade 4- forefoot gangrene
grade 5- full-foot gangrene
what are the 3 critical phases of peripheral vascular disease?
- collateral circulation insufficient for metabolic needs
- claudication- pain with activity
- rest pain- requires revascularization surgery
in arterial wounds: will ABI and pulses be diminished?
yes
what is the normal time during a capillary refill exam
less than 3 sec
which are more common venous or arterial wounds?
venous
What are 3 causes of chronic venous insufficiency?
- reflux as a result of incompetent valves in the perforator, superficial, or deep veins
- obstruction- chronic deep vein thrombosis
- lack of venous pump activation during the gait cycle
