Terms in this set (51)
Very large, thin-walled veins
Inappropriate elevation in the blood glucose level, disturbed lipid and protein metabolism.
Peripheral manifestation of generalized atherosclerosis. Most common form of chronic occlusive arterial disease in LE's.
Earliest symptom: Intermittent claudication
Threshold for intermittent claudication
50% for pain with activity
80-90% for resting pain
Peripheralized atherosclerosis; causes intermittent claudication. Affects young, male smokers predominantly. Inflammatory process begins distal and proceeds proximally.
Also known as
(need to know)
Acute Arterial Occlusive Disease
May be from arterial embolism, arterial thrombosis, or vasospastic diseases
Know the 5 P's of classic s&s
Spasm of arterioles affecting the digits. Cyanosis of digits with cold or emotional upset, followed by intense redness/warmth.
Cyanosis of distal extremities, usually affecting hands/fingers or feet and toes. Caused by arterial spasm.
No rebound erythema
(difference between this and Raynaud's)
Bilateral vasodilations affecting extremities esp. feet. Redness, burning, throbbing, and increased skin warmth.
Idiopathic and no definable cause for episodes.
Obstruction of blood flow secondary to collection of coagulated blood
"Charlie horse"; inflammation of tissues around vein will occur
Superficial Venous Thrombosis (SVT)
Conspicuous cordlike nodules that can be palpated
Chronic Venous Insufficiency
Venous hypertension in unilateral LE; venous reflux
80% of LE ulcerations result from CVI
Inflammatory condition of skin caused by pooling blood
Stasis pigmentation - iron in hemoglobin sets and stains tissues it settles in
Lymphedema - Primary v. Secondary
Failure of transport system causes an increase in protein-rich fluid, damaging arterial & venous systems
: Acquired - common with breast ca survivors with mastectomy
Swishing sound indicative of turbulence (heard in circulatory system)
Lower Extremity Amputation Prevention
*5 steps - in PVD powerpoint
disintegration or liquidification of tissue or of cells by the body's own mechanisms, such as leukocytes and enzymes
covered with dried secretions
removal of epiderms
denuding by mechanical means
dry, black or brown, leathery material that is the result of destruction of cells/blood vessels and desication of devitalized tissue
to soften by wetting or soaking; refers to degenerative changes and disintegration of skin when it has been kept too moist
dried exudate covering superficial wounds, usually containing
moist yellowing or gray substance composed of a mixture of fibrin tissue debris and pus that contains bacteria and leukocytes
Enzymatic (chemical) Debridement
topical application of proteolytic substance (enzymes) to breakdown devitalized tissue
used for chronic venous ulcers;
- makes scabz
FOAM Dressings may be impregnated with what to decrease odor?
chemical/medicine applied to eschar after cross-stitching
enzyme for chemical debridement that is
most effective on yellow-green fibrotic tissue and eschars
enzyme for chemical debridement that is
specific for fibrin products
, such as dried blood
May be caused by too much O2 - Epithelialization is stopped as epithelial cells can't climb the hump of tissue against gravity.
Tissue necrotization must occur via silver nitrate sticks
tissue defect extending at least to the subcutaneous layer
any open area produced as a result of undermining, tunneling or sinus tracking.
Contains blood vessels, nerve endings, epidermal appendages; Composed of collagen and elastin fibers; Thickness depends on site and function.
Functions for protection, sensation, temperature control; Stratum corneum - outermost layer. Sloughs every 28 days; Basal cell layer - adjacent to dermis and divides constantly; Thickness depends on site and function
Abnormal passage between two organs or between an organ and the outside of the body. May be placed on purpose e.g. G-tube.
A soft cavity or channel without defined edges that involves an area larger than the visible surface of the wound.
Fatty tissue, not well vascularized
Deeper open space with defined walls
The rim of the wound is eroded beneath the surface
Firmness/rigidity of skin.
Splitting of a wound after surgery from the skin being pulled too taut. Generally stitches hold and skin around it tears.
Containing non-replicating bacteria/micro-organisms or foreign material.
*All chronic wounds contain microorganisms
Containing replicating microorganisms adherent to the wound but not injuring host.
*Indication of infection such as purulent exudate, foul odor, or surrounding inflammation
*All stage 2-4 pressure ulcers are colonized
Containing replicating microorganisms within a wound with damage to the host
Culture and sensitivity
What you lack.
Jk bro, we cool? - diagnostic lab test for bacteria where a sample is grown and analyzed for sensitivity to antibiotics
Do aerobes or anaerobes comprise the majority of contaminants?
Anaerobes - grow in absence of free oxygen and therefore live deeper in wounds
A substance that prevents or arrests the growth of microorganisms by preventing multiplication
Agent that prevents or arrests the action of microorganisms by either inhibiting their activity or killing them
An agent used on living skin that is either bactericidal or bacteriostatic
