Possible signs of
IMPAIRED ARTERIAL CIRCULATION
|
-loss of leg hair
-shiny skin on legs
-more easily damaged
|
|
1)STEROIDS cause...
2)ANTIBIOTICS cause...
|
1)thinning skin
2)increased sensitivity to sunlight
|
|
CLEAN WOUNDS
|
-uninfected
-minimal inflammation
-primarily closed wounds
|
|
CONTAMINATED WOUNDS
|
-open, fresh, accidental
-surgical wounds w/ major break in sterile technique
-inflammation
|
|
DIRTY/INFECTED WOUNDS
|
-old, accidental
-has dead tissue
-evidence of clinical infection (purulent drainage)
|
|
1)PARTIAL-THICKNESS WOUND
2)FULL-THICKNESS WOUNDS
|
1)confined to the dermis&epidermis
2)involves dermis,epidermis,subcu+possible muscle & bone
|
|
PRIMARY (1ST) INTENTION HEALING
|
-tissues surfaces have been approximated
-minimal to no tissue loss
-minimal granulation tissue & scarring
-ex:closed surgical incision
|
|
SECONDARY INTENTION HEALING
|
-extensive, considerable tissue loss
-edges should/could not be approximated
-longer repair time, greater scarring, greater risk for infection
|
|
PHASES OF WOUND HEALING
1)INFLAMMATORY PHASE
|
-starts right after injury til day 3-6.
-hemostasis & phagocytosis
|
|
HEMOSTASIS
|
-cessation of bleeding
-vasoconstrict, retract injured bloodvessels
-fibrin (connective tissue)
-bloodclot: framework for cell repair (scab)
|
|
PHAGOCYTOSIS
|
-macrophages(WBCs) eat microorganisms&cell debris.
|
|
PHASES OF WOUND HEALING
2) PROLIFERATIVE PHASE
|
-day 3-21 postinjury
-fibroblasts go into wound 24hrs postinjury, synthesize collagen for strength, deposits fibrin.
-granulation tissue
|
|
GRANULATION TISSUE
|
-translucent red color, fragile, bleeds easy
-fills wound area when skin edges are not sutured
|
|
ESCHAR (scar tissue)
|
-dried plasma proteins & dead cells
-when wound does not close by epithelialization
|
|
PHASES OF WOUND HEALING
3)MATURATION
|
-day 21 to 1-2yrs postinjury
-fibroblasts synthesize collagen
-fibers reorganize
-wound is remodeled
|
