what are the precautions of using a foam dressing
dry wounds or wound with eschar or with amorphous hydrogel in a dry cavity
hydrogel dressings are ___% to __% water/glycerin based

gels
hydrogels can either be ___ or gels
sheets
hydrogel dressings are great for (slough/eschar) filled wound beds
eschar
can you use sheet hydrogel on an infected wound
no
can you use gel hydrogel dressings on an infected wound
yes
what are the effects of hydrogel dressings
moist environment, autolytic debridement, relieve pain, absorbs mild to moderate moisture
what are the indications for using amorphous hydrogel dressings
dry wounds or wounds with eschar
chicken pox and shingles
what are the indications for using sheet hydrogel dressings on wounds
prevent dryness of tissues such as tendons
they can carry topical drugs to wounds
What are the indications for stopping the use of amorphous hydrogel
if wound exudate is excessive
what are the indications for stopping the use of sheet hydrogel dressing
if the wound becomes infected
how long can hydrogel dressings stay on
about three days
True or False:
sheet hydrogels should not be use in small cavity wounds
true
amorphous hydrogels should not be used on patients who have a sensitivity to ____ ___
propylene glycol`
does a sheet hydrogel dressing require a secondary dressing
yes
does a hydrocolloid dressing require a secondary dressing
no
which type of dressing has gelatin particles suspended on a backing and is available in granules, powder, or paste
hydrocolloids
hydrocolloid dressings may leave residue or an ____ in the wound
odor
what are the effects of using a hydrocolloid dressing
moist wound environment
autolytic debridement
waterproof
protect from microbial contamination
does a sheet alginate dressing require a secondary dressing
yes
what are the indications of using hydrocolloids
superficial leg ulcers burns donor sites pressure ulcers over sutures
what are the indications for stopping hydrocolloid dressings
surface or hyper granulation
would you use a hydrocolloid dressing on an infected wound
no
which type of dressing is highly absorbent and has calcium and/or sodium salt
alginates
alginate dressings form a ____ yet keep their basic structure
gel
what are the effects of alginate dressings
moist wound environment highly absorbent conforms to body protects microbial contamination provide hemostasis
what are the indications for using an alginate dressing
lots of exudate
leg ulcers
cavities
pressure wounds
can you use a alginate dressing on an infected wound
yes
what are the indications for stopping alginate dressing
insufficient exudate
does a rope alginate require a secondary dressing
yes
what type of dressings are similar to hydrocolloids but are not gel forming and swell as they absorb exudate
hydroactive
what are the effects of the hydroactive dressings
high absorption waterproof surface autolysis no residue semipermeable to moisture vapor
what are the indications of using hydroactive dressings
exuding wounds leg ulcers pressure wounds minor burns wounds over joints
do you use hydroactive dressings over an infected wound
no
what are indications to stop using hydroactive dressings
not enough exudate (light exudate
where does a matrix dressing come from
a porcupines small intestine
when should you use a collagen dressing
when you need to promote fibroblasts
when should you use hypertonic saline
to manage hypergranulation
when should you use proteolytic enzymes
when you use enzymatic debridement
what are two topical antimicrobials used with dressings
silver and iodine
when are silver topical antimicrobial dressings used
for reduction of bioburden or burns and to reduce risk of infection
is silver dressings long term or short term
short term
when are iodine topical antimicrobials dressings used
to fight against bacteria, mycobacteria, fungi, protozo and viruses
also is usually used as a skin prep
What type of acute wounds can be treated with an antibiotic
traumatic wounds and major burns
infected wounds need a (local/systemic) antibiotic
systemic
Topical antibiotics (are/are not) generally recommended for infected chronic wounds, but the exception is for surface anaerobic contamination
are not
List all of the dressings from most absorbent to least absorbent
alginate foam gauze hydrocolloid hydrogel film
