C6 Flashcards
are there blood vessels in the epidermis layer?
no
which layer is absent in thin skin
clear layer
what are examples of non-viable Tissue?
necrotic tissue - black/purple colour due to dehydration
eschar - thick, dry, black, leathery
slough - moist, yellow
what does an Infection look like?
formation of pus, necrosis, foul odour, delayed healing
-> usage of antimicrobials or debridement
what are the other 2 wound bed preparation?
Moisture imbalance and non-advancing wound Edge
which dressing comes into contact with the wound and highly absorbent to absorb exudate?
primary dressing not secondary
cautions of (1) antiseptics
- should be used in eyes or over large areas of body, deep wounds, puncture wounds or animal bite & infected wounds
- should not be used for > 1 week unless directed by Dr
indication of (2) adhesive tapes
wound closure & securing non-adhesive dressings over a wound to help prevent infection
what should (4) gauze not be used for?
- not useful on dry wounds
- not recommended for moderate to heavily exudative wounds -> often sticks to wound surface
cautions of (5) semi-permeable film dressings
- avoid in infected wounds
- should not be used when anaerobic bacteria are suspected
- not useful for wounds with heavy exudate
cautions of (6) hydrocolloids (sheets/paste)
- not preferred in infected wounds, unless with antimicrobial
- not good for fragile surrounding skin
indication of (6) hydrocolloids
low to moderately exuding wounds such as pressure sores, leg ulcers, minor burns…
(7) hydrogels (sheet/gel)
- not useful for wounds with heavy exudates
- may be used as primary or secondary dressings
cautions of (8) foam dressings (sheet/tubes)
not useful for dry wounds, necrotic wounds or hard eschar
cautions of (9) alginates (sheet/rope)
do not apply to dry or necrotic wounds or wounds with low exudate as dressing can adhere to wound surface
not applicable for full thickness wound & 3rd degree wounds
examples of (10) antimicrobial dressings
silver dressing - antimicrobial & bactericidal properties, should only be used for 2-3 weeks
chlorhexidine dressing - bacteriostatic & bactericidal properties, disinfectant & antiseptic before surgery
what is an exudate wound
consists of fluid
wound dressing selection for low moisture level
hydrogel (gel/sheet) dressing
- gently re-hydrate dry necrotic tissue
- loosen & absorb slough & exudate
- provide a moist environment
wound dressing selection for low to moderate moisture level
hydrocolloid dressing
- absorb low levels of exudate while maintaining a moist environment
- for partial thickness wound
wound dressing selection for moderate to heavy moisture level
foam dressing or alginate dressing
- provides thermal insulation, high absorbency, moist wound environment, gas permeable
- available as adherent or non
wound debridement needed
