wound healing Flashcards
1 STAGE name
vascular response/hemostasis
hemostasis activities
- blood vessels constrict
- clotting factors to anticoagulate
- platelets release growth factors to attract cells needed to begin repairing
onset of stage #1
immediate
2 STAGE name
inflammatory
2 stage activities
vasodilation
leukocytes arrive
macrophages eat
cleaning up of wound bed
onset of inflammatory
immediate
duration of inflammatory
4-6 days
3 STAGE name
proliferative
3 stage activities
epithelialization, proliferation
granulation**
angiogenesis (new capillaries)
collagen synthesized to provide strength to wound bed
proliferative onset
1-4 days
proliferative duration
14-21 days
4 STAGE name
maturation
maturation activities
collagen remodeled to become stronger and provide tensile strength to wound
outer appearance in noncomplicated wounds is a well healed scar
maturation onset
14-21 days
maturation duration
up to 2 years to stabilize in appearance
primary intention
sutures/wound closures used to approximate edges (surgical incision); but doesnt have to have sutures (ie paper cuts); well-approximated
secondary intention
wound left open (ie pressure ulcer)
tertiary intention
delayed primary closure
- a contaminated wound, or in cases of edema++/inflammation, is left open and closed 3-5+ days later with staples/sutures
- high infection risk, needs to be well-controlled and sterile environment
granulation tissue
red
result of increasing amount of new blood vessels
considered healthy
slough tissue
yellow
nonviable tissue and in some cases indicates infection
eschar
black/brown
represents full thickness tissue destruction
necrotic tissue
assessment acronym for wounds
