Cards

Term
abrasion
Definition
Scraping or rubbing away of epidermis; may result in localized bleeding and later weeping of serous fluid.
Term
blanching
Definition
Whitening of the skin from pressure, vasoconstriction, or hypotension.
Term
debridement
Definition
Removal of dead tissue from a wound.
Term
dehiscence
Definition
Separation of a wound's edges that reveals underlying tissues.
Term
eschar
Definition
Scab or dry crust that results from excoriation of the skin.
Term
evisceration
Definition
Protrusion of visceral organs through a surgical wound.
Term
exudates
Definition
Fluid, cells, or other substances that have been slowly discharged from cells or blood vessels through small pores or breaks in cell membranes.
Term
fistula
Definition
Abnormal passage from an internal organ to the body surface or between two internal organs.
Term
granulation tissue
Definition
Soft, pink, fleshy projections of tissue that form during the healing process in a wound that is not healing by primary intention.
Term
hematoma
Definition
Collection of blood trapped in the tissues of the skin or an organ.
Term
hemostasis
Definition
Termination of bleeding by mechanical or chemical means or by the coagulation process of the body.
Term
induration
Definition
Hardening of a tissue, particularly skin, because of edema or inflammation.
Term
laceration
Definition
Torn, jagged wound.
Term
pressure ulcer
Definition
Inflammation, sore, or ulcer in the skin over a bony prominence.
Term
primary intention
Definition
Primary union of the edges of a wound that progresses to complete scar formation without granulation.
Term
purulent
Definition
Producing or containing pus.
Term
sanguineous
Definition
Fluid containing red blood cells.
Term
secondary intention
Definition
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 healing by primary intention.
Term
serosanguineous
Definition
Containing both serum and blood.
Term
serous
Definition
A clear (like plasma) fluid that forms an exudate at the site of an inflammation.
Term
shearing force
Definition
Friction exerted when a person is moved or repositioned in bed by being pulled or allowed to slide down in bed.
Term
slough
Definition
Shedding off of dead tissue cells.
Term
sutures
Definition
Wound closing similar to sewing
Term
tertiary intention
Definition
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. Suppuration (formation or discharge of pus) is also usually found.
Term
tissue ischemia
Definition
Point at which tissues receive insufficient oxygen and perfusion.
Term
Vacuum Assisted Closure (VAC)
Definition
Trademark for a system that uses the controlled negative pressure of a vacuum to promote healing of certain types of wounds, such as chronic wounds, burns, or wounds that are expected to present difficulties while healing. 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. Also called negative pressure wound therapy (NPWT).
