Skin Integrity Flashcards
clean wounds
closed, intact, not infected
clean-contaminated wounds
surgical wounds - no infection
contaminated wounds
open, accidental or surgical - involves major break in sterile technique
dirty & infected wounds
show evidence of infection
partial thickness wounds
dermis & epidermis healing by regeneration (on its own)
full thickness wounds
all 3 layers of tissue - possible muscle & bone - requires tissue repair
etiology of pressure wounds
ischemia
reactive hyperemia
blanchable bright red flush to skin when pressure removed - results from vasodilation
pressure ulcer risk factors
friction & shearing Immobility Inadequate nutrition Incontinence - can cause maceration Decreased mental status Diminished sensation Excessive body heat Advanced age Chronic medical conditions
stages of pressure ulcers
Stage 1—Nonblanchable erythema
Stage 2—Partial-thickness skin loss - to dermis - open or closed ulcer
Stage 3—Full-thickness skin loss - SQ visible
Stage 4—Full-thickness skin loss c necrosis - muscle, tendon, ligament, bone visible
epibole
edges of ulcer roll under & damage to skin extends beneath roll
slough and eschar prevent us from…
assessing depth
staging injury
Deep tissue pressure injury
Purple or black intact skin - blackish blistered area - heavy or spongy at palpation
prevention of pressure ulcers
Assess pt’s risk factors q shift - Braden Scale
Keep skin dry & clean
Use barrier creams
Wrinkle-free linens
Turn q 2 hrs
Watch friction & shear
Special air beds & devices for pts c high risk
components of braden scale
sensory perception moisture activitiy mobility nutrition friction & shear
braden scale explain scores
the higher the score, the less risk for an ulcer
Primary intention healing
tissue surfaces approximate - minimal/no tissue loss - minimal granulation tissue & scarring
secondary intention healing
extensive tissue loss - no approximation - repair time longer - scarring greater - susceptibility to infection
tertiary intention healing
leave wound open for 3-5 days until edema/drainage is gone - closed with sutures, staples, adhesives
phases of healing
inflammation
proliferative
maturation
dehisence
rupture of sutured wound - partial or total - usually involves abdominal wound c layers beneath skin also separating
evisceration
what do you do?
4-5 days post op - protrusion of internal organ through incision - emergency situation - organ is exposed - immediately put on sterile wet dressing, then call physician
