Week 4 quiz study guide Flashcards
collagen dressing
made from bovine, porcine into sheets, pads, powders, gels.
for partial, full thickness, contaminated or infected wounds.
stim wounds to produce collage fibers/granulation tissue
non stick
antimicrobial dressing
topical antifungal, antibx agents
silver and cadexomer iodine common ingredients
for partial, full thickness, malodorous wounds; little to large amt of drainage; highly contaminated or infected wound
gauze dressing
simplest, most widely used.
woven material cotton, rayon polyester.
can be medicated or moistened.
sterile and non sterile.
for packing large wounds, cavities, tracts; deep dirty wounds, heavy draining wounds.
cons - labor intensive, costly, sticks, allows for evap, must be fluffed, frequent dressing changes causes disruption to wound.
absorption dressing
highly absorptive; for moderate to large amt of exudate; use as primary (direct contact) or secondary dressing for partial or full thickness wounds. not used for packing undermining wounds
alginate dressing
made from seaweed and kelp; absorbs 20-40x their weight;
for large amt of exudate, ideal for tracts, depth, tunneling, undermining;
will adhere to wound bed if no drainage. creates nonadhesive gel with exudate - must be irrigated.
foam dressing
semipermeable hydrophilic foam to form impermeable barrier made into wafers, rolls, pillows; adhesive and non adhesive;
absorbs minimal to heavy exudate.
provides moist environ and thermal insulation.
choose 2-3 cm larger than wound. change up to 3 times a week.
conforms, contours, non stick.
not for tunneling or tracts, not for dry desiccated wounds
may macerate periwound skin if wet.
hydrocolloid dressing
wafers, pastes, powders that contain hydrophillic particles.
interacts with exudate to form gel that keeps wound moist. for wounds with minimal damage, partial thickness, stage II; used to fill shallow cavities around stomas.
molds to body; decreases pain; promotes autolytic debridement.
use 3-4 cm larger than wound; do not wafer; doesn’t need frequent changing; secondary dressing not required; clean wound bed if odorous.
hydrogels
sheets, granules, gels with high water content, creates jelly like substance that doesn’t stick to wound.
soft and cooling, provides moisture, softens slough or eschar.
don’t need secondary dressing.
limited absorption, high moisture can macerate skin.
skin sealants and moisture barriers
made from transparent copolymer that can be wiped or sprayed on skin. protects skin from exudate and moisture, friction, skin stripping from adhesives.
ointments impair that adhesion of wound dressings or tapes.
transparent film dressings
clear and semipermeable. allows for exchange of air and water vapor.
non absorbent, keeps wound moist, useful for wounds with minimal drainage; often used for IV sites.
can view wounds without removing dressing.
cons: with wounds that a draining, will cause maceration. not for friable skin.
adhesive tape
provides stability to dressing. leaves residue on skin, can cause trauma to intact skin.
foam tape
molds to contour of body; ideal over joints
nonallergenic tape, paper tape
best for sensitive skin; allergies to tape.
montgomery straps
has ties to secure the dressing, decreases the amount of pulling and irritation to skin.
sharp debridement
use sterile instruments
