Term
Abnormal reactive hyperemia
Definition
hyperemia over a pressure site lasting more than one hour after the removal of pressure; surrounding skin does not blanch
Term
Abrasion
Definition
superficial with little bleeding and is considered a partial-thickness wound
Term
Approximated
Definition
closed
Term
Blanching
Definition
when the normal red tones of the light-skinned patient are absent
Term
Collagen
Definition
a tough, fibrous protein
Term
Debridement
Definition
the removal of nonviable, necrotic tissue
Term
Dehiscence
Definition
the partial or total seperation of wound layers
Term
Drainage evacuators
Definition
convenient portable units that connect to tublular drains lying within a wound bed and exert a safe, constant, low-pressure vacuum to remove and collect drainage
Term
Epithelialization
Definition
the process by which epidermal cells migrate over the wounds surface to close the top or "resurface" the wound
Term
Eschar
Definition
scab or dry crust taht results from excoriation of the skin
Term
Evisceration
Definition
protrusion of visceral organs through a wound opening
Term
Exudate
Definition
describes the amount, color, conisistency, and odor of would drainage and is part of the wound assessment
Term
Fibrin
Definition
an insoluble protein that is essential to clotting of blood, formed from fibrinogen by action of thrombin
Term
Friction
Definition
the force of two surfaces moving across one another
Term
Granulation tissue
Definition
red, moist tissue composed of new blood vessels, the presence of which indicates progression toward healing
Term
Hematoma
Definition
localized collection of blood underneath the tissues
Term
Hemorrhage
Definition
bleeding from wound site
Term
Hemostasis
Definition
a series of events designed to control blood loss, establish bacterial control, and seal the defect occurs when there is an injury
Term
Induration
Definition

Term
Slough
Definition
stingy substance attached to wound bed
Term
Sutures
Definition
threads or metal used to sew body tissues together
Term
Tissue ischemia
Definition
when the pressure applied over a capillary exceeds the normal capillary pressure and the vessel is occluded for a prolonged period of time
Term
Vacuum-assisted closure (V.A.C.)
Definition
a device that assists in wound closure by applying localized negative pressure to draw the edges of a would together
Term
Wound
Definition
a disruption of the integrity and function of tissues in the body
Term
Wound contraction
Definition
the shrinkage and spontaneous closure of open skin wounds
