|
dermis
|
thicker, produces collagen and elastin home for lymphatic vessels and nerve tissues.
|
|
temp reg
|
dilation and constriction of blood vessels regulates body temp
|
|
skin
|
makes vit. D to aid in calcium absorption and phosphorous
|
|
primary intention wound
|
shorter healing time. wounds approximated, surgical incision
|
|
secondary intention wound
|
primary will become 2nd if get infected.
large with considerable tissue loss. healing by formation of granulated tissue. >infection >longer healing >scars |
|
wound assessment
|
-appearance, inspection and palpation.
-size -drainage: assess amount, color, odor, and consistency -pain: incisional pain is usually severe for the 1st 2-3 days. if increased or acute, sign of delayed healing. -sutures, drains, tubes -evidence of complications |
|
Pressure Ulcer assessment
|
size: draw shape and describe.
depth: steril swab w/ saline @ 90degree angle. mark pt on swab that is even with surrounding skin. presence of undermining: tunneling, or sinus tract. saline sterile swab under wound edge. |
|
stage I pressure ulcer
|
change in temp (cool/warm)
change in tissue consistency change in sensation pink-caucasians blue/purple-blacks |
|
stage II pressure ulcer
|
partial thickness skiin loss. presents as blister, shallow crater
|
|
stage III pressure ulcer
|
full thickness skin loss. damage/necrosis of dermis not to underlying fascia.
|
|
Stage IV pressure ulcer
|
full thickness skin loss with extensive destruction, necrosis, damage to muscle, bone, or supporting structure. sinus tracts can be associated.
|
|
turgor
|
elasticity of skin
|
|
hyperkeratosis
|
skin thickening, flaking, scales
|
|
abnormal skin color
|
(normal is even toned, w/o variation)
pallor-poor circulation cyanosis-low O2 jaundice-liver disease |
|
dermatitis
|
rash. if rash is all over body, usually a drug or food allergy
|
|
inflammatory phase
|
1st phase in wound healing.
hemostasis. -vasoconstriction -immediate -blood clotting -leukocytes |
|
proliferative phase
|
second phase.
-epitheliazation -fibroblasts (conn tissue) -granulation -lasts 2days-3wks |
|
maturation phase
|
3rd stage
-remodeling -collagen remodeled -contraction -scar -3wks to 2 years. |
|
scar
|
avascular, doesn't sweat, grow hair, or tan in sunlight.
-fire victims can't thermoregulate body |
|
sterognosis
|
sensation to touch
|
|
skin assessment
|
-temp
-color -moisture -turgor -integrity |
|
edema
|
a decrease in skin mobility due to accumulation of fluid in intercellular spaces.
-not a normal finding -document on 4-pt scale |
|
acute wound
|
-surgical incision
-healing within days to weeks -edges well-approximated -decreased risk for infection |
|
chronic wound
|
-pressure ulcers, peripheral arterial or venous ulcers
-normal healing time is delayed -edges not approximated -increased risk for infection -bacterial counts >100,000 per gram of tissue impede healing |
|
older adult: factors affecting wound healing
|
-slower inflammatory response
-reduced antibody productiona nd endocrine system function -increased incidence of chronic illness such as DM and CVD that compromise circulation and tissue oxygenation -decreased secretion of enzymes and absorption of nutrients and minerals |
|
factors affecting wound healing
|
-age
-circulation and oxygenation (obese people/ few bld vessels) -nutritional status -wound condition -health status: corticosteroids decrease the inflammatory process |
|
evisceration
|
protrusion of viscera through the incision area.
risk factors: obesity/malnurishment, infected wounds, excessive coughing/vomiting, or straining. -an increase in the flow of serosanguineous fluid from teh wound btwn postoperative days 4 and 5 indicates an impending dehiscence. -cover with sterile towel soaked in NS, notify doctor |
|
fistula
|
an abnormal passage from internal organ to the skin or from one internal organ to another.
signs: drainage from an opening in the skin or surgical site, pain. -risk for fluid and electrolyte imbalance, skin breakdown, and infection |
