-
pressure ulcer
"Inflammation, sore, or ulcer in the skin over a bony prominence. (Potter 1189)"
-
primary intention
"Primary union of the edges of a wound, progressing to complete scar formation without granulation. (Potter 1189)"
-
reactive hyperemia
redness of the skin resulting from dilation of the superficial capillaries (Potter 1059)
-
secondary intention
"Wound closure in which the edges are separated, granulation tissue develops to fill the gap, and, finally, epithelium grows in over the granulation, producing a larger scar than results with primary intention. (Potter 1190)"
-
shear
Force exerted against the skin while the skin remains stationary and the bony structures move. (Potter 1190)
-
sitz bath
Bath in which only the hips or buttocks are immersed in fluid. (Potter 1191)
-
tissue ischemia
Point at which tissues receive insufficient oxygen and perfusion. (Potter 1192)
-
Approximated
"To come close together, as in the edges of a wound."
-
Blanching
turn lighter in color
-
Catarrhal
"inflammation of a mucous membrane, particularly of the head and throat, with free discharge of mucus"
-
Collagen
"The fibrous protein constituent of bone, cartilage, tendon, and other connective tissue that converts into gelatin by boiling."
-
Debriment
Removal of dead tissue from a wound.
-
Drainage evacuators
"Convenient portable units that connect to tubular drains lying within a wound bed and exert a safe, constant, low-pressure vacuum to remove and collect drainage. (Potter 1181)"
-
Epithelialization
healing by the growth of epithelium over a denuded surface

"an insoluble protein that is essential to clotting of blood, formed from fibrinogen by action of thrombin"
-
Puncture
the act of piercing or penetrating with a pointed object or instrument; a wound so made.
-
Purulent
"Containing, discharging, or causing the production of pus."
-
Sanguineous
Of or relating to blood; bloody.
-
Serous
"Containing, secreting, or resembling serum"
-
Slough
"A layer or mass of dead tissue separated from surrounding living tissue, as in a wound, a sore, or an inflammation"
-
Sutures
material used in closing a wound with stitches
-
Tertiary intention
"wound closure in which granulation tissue fills the gap between the edges of the wound, with epithelium growing over the granulation at a slower rate and producing a larger scar than the scar resulting from healing from secondary intention"
-
Vacuum Assisted Closure
"The edges of the wound are made airtight with foam and a dressing, and a tube is placed in the wound, connecting to a canister that creates a vacuum. Infectious materials and other fluids are then sucked out of the wound."
-
Wound
a disruption of normal skin structure and function
-
Wound contraction
the shrinkage and spontaneous closure of open skin wounds
