terminology Flashcards
serous exudate
clear, light, thin, watery consistency
- normal in healthy healing observed during inflammatory and proliferative phase
sanguineous exudate
red (blood), thin, watery consistency
- may be indicative of new blood vessel growth or disruption of blood vessels
serosanguineous exudate
light red/ pink, thin watery consistency
- normal in healthy healing observed during inflammatory and proliferative phase
seropurulent exudate
cloudy, opaque, yellow/ tan color, thin watery consistency
- may be an early warning sign of impending infection and is always considered abnormal
purulent exudate
yellow/green, thick, viscous
- generally indicator of wound infection and is always considered abnormal
eschar
hard, leathery, black/brown dehydrated tissue that tends to be firmly adhered to the wound bed
gangrene
death and decay of tissue resulting from an interruption in blood flow to an area of the body
- can also occur in muscles and organs
hyperkeratosis
callus
- white/ gray in color and can vary in texture from firm to soggy depending on moisture level
slough
moist, stringy, mucinous, white/yellow tissue that tends to be loosely attached in clumps to the wound bed
contusion
injury caused by a blow that does not disrupt skin integrity
- pain, edema, and discoloration, as a result of blood seepage under the surface of the skin
dehiscence
separation, rupture, or splitting of a wound closed by primary intention
dermis
vascular layer of skin located below epidermis containing hair follicles, sebaceous glands, sweat glands, lymphatics, blood vessels and nerve endings
desiccated
drying out or dehydration of a wound
-results from poor dressing selection
desquamation
peeling or shedding of outer layers of epidermis
ecchymosis
-bruise
discoloration occurring below intact skin resulting from trauma to underlying blood vessels and blood seeping into tissues
- typically blue/ black changing in time to greenish brown or yellow color
epidermis
superficial, avascular epithelial layer of skin including flat, scale-like squamous cells, round basal cells, and melanocytes
erythema
diffuse redness of skin often resulting from capillary dilation and congestion or inflammation
friable
tissue that easily tears, fragments or bleeds when gently palpated or manipulated
hematoma
localized swelling or mass of clotted blood confined to a tissue, organ or space usually caused by a break in a blood vessel
hypergranulation
increased thickness of granular layer of the epidermis that exceeds the surface height of the skin
normotrophic scar
scar characterized by the formation of collagen fibers that align in parallel fashion
turgor
relative speed at which the skin resumes it normal appearance after being pinched
- tests hydration
allograft (homograft)
temporary skin graft taken from another human, cadaver, in order to cover a large burned area
autograft
permanent skin graft taken from a donor site on the patients own body
escharotomy
opens or removes eschar from a burn site to reduce tension on surrounding structures, relieve pressure from interstitial edema, and subsequently enhance circulation
full-thickness graft
a skin graft that contains the dermis an epidermis
heterograft (xenograft)
temporary skin graft taken from another species
mesh graft
skin graft that is altered to create a mesh-like pattern in order to cover a larger surface area
recipient site
a site that has been burned and requires a graft
sheet graft
skin graft that is transferred directly from the unburned donor site to the prepared recipient site
split-thickness graft
skin graft that only contains superficial layer of the dermis in addition to the epidermis
z-plasty
surgical procedure to eliminate a scar contracture, and incision in the shape of a āzā allows the contracture to change configuration and lengthen a scar
