Dressings lecture chart Flashcards
what are gause permeability?
non-occlusive
What are the 5 types of moderately-highly absorbent dressings?
gause
alginates
hydrofiber
foams
what special characteristics of gauze?
can be woven or non woven
non woven= better absorbency
wrapping gauze
primary= absorbency
Secondary= bulk Cushing
What is gauze used for?
● wet-to -dry dressings to pack
wound with undermining or
filling cavernous wounds
● Acute surgical wound incisions
● Highly draining wounds
● Infected wounds
what is gauze poor for?
● Clean
granulating and
epithelializing
wounds
● Exposed bone,
tendons, mesh,
grafts
● Third degree
burns
● Minimal
exudate/dry
wound
what type of permeability is alginates?
non-occlusive
what special characteristics of gauze?
Highly absorbent, conforms to body
shape, doesn’t adhere to wound
bed, hemostatic
Will need a secondary dressing
what are alginates used for?
● Maintains wound moisture
● Provides autolytic debridement
● Acute surgical wound incisions
● Highly draining wounds
● Infected wounds
Good for full or partial thickness
wounds with mod-heavy exudate and
bleeding wounds
what are alginates bad for?
● Clean
granulating and
epithelializing
wounds
● Exposed bone,
tendons, mesh,
grafts
● Third degree
burns
● Minimal
exudate/dry
wound
what type of permeability is hydro fiber?
non-occlusive
what are the special characteristics of hydro fiber?
Same as alginates except it is NOT
a hemostat
Will need a secondary dressing
what are hydro fiber used for?
● Maintains wound moisture
● Provides autolytic debridement
● Acute surgical wound incisions
● Highly draining wounds
● Infected wounds
Good for full or partial thickness
wounds with mod-heavy exudate and
bleeding wounds
what are hydrofibers poor for?
● Clean
granulating and
epithelializing
wounds
● Exposed bone,
tendons, mesh,
grafts
● Third degree
burns
● Minimal
exudate/dry
wound
what permeability is foam?
semi-occlusive/semi-permability
what are the special characteristics for foam?
Moderate-highly absorbent,
conforms to body shape, does not
adhere to wound bed, provides no
residue.
May or may not have an adhesive
border; if none, will need
securement
what is foam used for?
● Maintains wound moisture
● Wound insulator
● Aids in autolytic debridement
● Primary for scant to moderately
draining wounds
● Secondary for moderately-highly
draining wounds
● Painful wounds as non-adherent
dressing
what is foam bad for?
● Infected wounds
● Highly draining
wounds
● Dry eschar
what are the types of dressings that are low-no absorbency?
hydrocolloids
transparent films
impregnated gauze
what is the permeability of hydrocolloids?
Occlusive
*primary= shallow minimally draining wound
secondary= deep cavity wound
what special characteristics are there for hydrocolloids?
Combo of gel-forming polymers
with adhesives into backing of film
or foam; conforms to body shape
Does not require a secondary
dressing
what are hydrocolloids used for?
● Maintains wound moisture
● Aids in autolytic debridement
● Provides insulation
● Minimally draining wounds
● For perineal/pelvic wounds
● Second skin for protection from
frequent dressing changes
● Dry wound or necrotic/granular
wound
what are hydrocolloids poor for?
● Infected wounds
● Highly draining wounds as a primary
● Thin fragile skin
● Third degree burns
● Exposed tendon/bone
what type of permeability is a transparent films?
semi-occlusive/semi-permeability
what are the special characteristics of transparent films?
Provides no absorbency; moisture
vapor and O2 permeable
what are transparent films used for?
● Maintains wound moisture
● Aids in autolytic debridement
● May function as a secondary dressing
what are transparent films poor for?
● Infected wounds
● Highly draining wounds
What is the permeability of impregnated gauze?
semi-occlusive/ semi-permeability
what are the special characteristics for impregnated gauze?
Primarily used as a contact layer
what are impregnated gauze poor for?
● Aids in autolytic debridement
● Primary for scant to moderately draining wounds
● Secondary for moderately-highly
draining wounds
● Painful wounds as non-adherent
dressing
what are impregnated gauze poor for?
Infected wounds
Highly draining wounds
what are hydrating types of wound bandages?
hydrogel
what permeability type is hydrogel
semi-permeable/semi-occlusive
what special characteristics do hydrogel have?
Conforms to body shape; does not
adhere to wound bed
what is hydrogel used for?
● Provides moisture to wound
● Promotes granulation/epithelialization
● Aids in autolytic debridement
● Relieves pain
what is hydrogel poor for?
● Infected wounds
● Highly draining wounds
● Third degree burns
what are the other misc types of wound dressings?
composites
contact layers
negative pressure wound therapy
what are composites used for?
Primary or secondary cover dressing
Provides autolytic debridement
Manages minimal to heavy exudates
what are antimicrobial wound dressings
Silver-based,
Iodine-based,
Honey-based,
Topical
antibacterials
what are antimicrobials used for:
Against different bacteria
what are enzymatic deriders?
Collagenase Santyl, Accuzyme, Panafil
what are enzymatic deriders used for?
Stimulates new tissue development.
Good for chronic, non-healing granulated wounds and partialthickness, tunneling wounds with minimal to heavy exudate
what are enzymatic deriders poor for?
● Third degree burns
● Sensitivity to specific debridger material
what are wound stimulating materials
Collagens,
Growth
Factors,
Biologicals,
Hypertonic
what are the special characteristics for wound stimulating materials?
they require a secondary dressing
what are wound stimulating materials used for?
chronic non-healing granulated
wounds (Ex: skin graft, tunneling, minimal to heavy exudates)
what are wound stimulating materials poor for?
Not good for 3rd-degree burns
