Types of wound dressings Flashcards
What is the purpose of transparent film dressings
to provide assessment opportunity
prevent fluid evaporation
What can transparent dressings do
exchange oxygen
impermeable to water and bacteria
What is are some sommon injuries that trans dressings are used for
IV dressings
Burns
central line dressings
Pressure ulcers
What are trans dressings made of
plastic
What is the purpose of impregnated nonadherant dressings
protect and soothe partial or full thickness wounds without exudate
What are impregnated nonadher dressings made of
woven/nonwoven cotton or synthetic impregnated with petrolatum, saline. zinc-saline, or antimicrobials
What do impregnated nonadherent dressings require
a seocondary dressing
What injuriess are impregnated nonadher dressings used for
postoperative staples and sutures
superficial burns
What are hydrocoloids made of
Waterproof adhesive wafers, pastes, or powders
What is the purpose of hydrocoloids
to absorb exudate
produce a moist environment
What injuries are hydrocoloids used for
pressure ulcers stage 2-4
Autolytic debridgment of eschar
partial thickness wounds
How long do hydrocoloids last
7 days
What are Clear absorbent acrylics made of
Transparent absorbent wafer
How long are Clear absorbent acrylics designed to last
5-7 days
What is the purpose of Clear absorbent acrylics
easy assessment
protection from bacteria and shearing
maintain moist evironment
What injuries are Clear absorbent acrylics used for
Skin tears
Wounds undergoing chemical debridgement agents
pressure ulcers
venous stasis ulcers
What are hydrogels made of
glycerin or water based nonadhesive jelly-like sheets, granules, or gels
What can Clear absorbent acrylics be used with
alginates
What is the purpose of hydrogels
To liquify necrotic tissue
rehydrate wounds
fill dead space
What are injuries that hydrogels are used for
pressure ulcers
skin tears
partial thickness wounds
Are hydrogels permeable or impermeable
permeable
Do hydrogels require secondary dressings
yes
What are polyurethane foam dressings made of
nonadherent hydrocoloid dressings
Do polyurethane foam dressings need a secondary dressings to become occlusive
yes
What is the purpose of polyurethane foam dressings
the absorb large amounts of exudate
to provide thermal regulation
maintain moist environment
What injuries are polyurethane foam dressings used for
light to highly exudating wounds pressure ulcers skin tears wounds undergoing chemical debridgement agents Venous stasis ulcers
What are alginates made of
nonadherent dressings of powder, beads or granules, ropes, sheets, or paste
What is the purpose of alginates
maintain moist environment by interacting with exudte
absobing exudate
eliminate dead space
What injuries are alginates used for
pressure ulcers skin tears venous stasis ulcers surgical wounds wounds undergoing chemical debridgement agents
Do alginate need a secondary dressing
yes
How much exudate can alginates absorb
20 times their weight
What are collagen dressings made of
gels pastes powders granules sheets and sponges derived from animal sources liek cows or pigs
What is the purpose of collagen dressings
assissting to stop bleeding
helps to stimulate cell recruitment and proliferation
What injuries are collagen dressing used fo r
clea, moist wounds
