wound healing Flashcards
three types of wound healing
primary, secondary, tertiary
type of wound healing
- edges of the wound are approximated
- wound is uncomplicated and clean
- little tissue loss
primary
type of wound healing
-edges are not approximated for first 3 to 5 days then are drawn together
tertiary
type of wound healing
- edges of the wound are not approximated
- high risk for scarring, infection
- wound is large, gaping, irregular
secondary
what are the phases of wound healing?
inflammation (3-5 days)
proliferation (3-21 days)
maturation/remodelling (21 days to 2 yrs)
tissue that is being formed, translucent red colour, fragile and bleeds easily
granulation tissue
- hypertrophic scar
- abnormal amount of collagen
keloid
material, such as fluid and cells, that has escaped from blood vessels during the inflammatory process
-deposited in tissue or on tissue surfaces
exudate
what are the three major types of exudate?
serous
purulent
sanguinous
exudate that contains mainly of serum (clear portion of blood)
serous exudate
- thick exudate
- presence of pus
purulent exudate
consists of leukocytes, liquified dead tissue debris and dead and living bacteria
pus
process of pus formation
suppuration
- exudate consists of large amounts of red blood cells
- indicates damage to capillaries that is severe enough to allow the escape of RBC from plasma
sanguinous exudate
exudate consisting of clear and blood tinged drainage
serosanguinous exudate
