Q

Alginates

A

composites of fibers made from seaweed or calcium alginate fibers

absorb 20x its own weight

exchange Na and Ca ions to form a gel

product manufacturing will determine wicking ability

newer hydrofibers are 30% more absorptive

18
Q

alginate disadvantage

A

requires Sec. dressing
can dry out or stick
may macerate intact skin if not applied correctly

19
Q

Antimicrobial dressing

A

derived from silver, Iodine

can be integrated into other dressings

used on draining or non draining sites

left in place multiple days

20
Q

Honey can be

A

Antibacterial

antifungal

sterile

gamma irradiated

21
Q

collagens

A

stimulate granulation tissue formation

tissue development

create environment to heal

partial to full thickness wounds

22
Q

pros / cons of collagen

A

pro - absorbent, maintain a moist wound environment, nonadherent, easy to use

cons- require secondary dressing, not for use on black eschar, or 3rd degree burns, VERY EXPENSIVE AND LAST RESORT, cannot have infections

23
Q

Composites

A

combine 2 or more physically distinct products into 1

may include physical barrier, absorptive layer, foam hydrocolloid, adhesive border

24
Q

composite pros and cons

A

pros- allow moisture vapor, mold well, facilitate debridement, easy to use, include adhesive border

cons - have to have good skin to secure dressing

25
Q

contact layer

A

single layers of some woven material with low adherence

may use this to prevent foam from sticking into wound bed

26
Q

contact layer pros vs cons

A

pros- protect wound, allow drainage to pass through, used with topical meds or fillers

cons - require secondary dressing, will not handle a viscous drainage

27
Q

foams

A

polyurethane, open-cell sheets, single or multi-layered

multiple varieties and thicknesses

may have incorporated charcoal or Ag

FOAM IS YOUR FRIEND

28
Q

foam indications

A 
pressure ulcers - all stages
partial - full thickness wounds
minor burns
surgical sites
minimal to heavy exudate
infected or non infected wounds

change 1-7 days depending on manufacturing

can be re- placed after checking/ cleaning wounds

29
Q

foam advantages

A 
highly absorbent
can be used in infection
available with or without border
facilitates AUTOLYSIS
atraumatic removal if non adherent
multiple applications
comes in Ag
30
Q

disadvantages of foam

A

may require additional securement
may macerate if over saturated
not recommended on dry eschar
may lint, dependent on quality

31
Q

hydrocolloids

A

semi occlusive dressings like gelatin, pectin, and other products - not used often anymore

maintain moist environment and help granulate or debride a wound

CANNOT BE ON INFECTED WOUND

32
Q

hydrocolloids pros

A

can handle light to mod drainage, minimize skin trauma, impermeable to bacteria, mold well to site

33
Q

hydrocolloids cons

A

not for infections, not for fragile periwound skin, may curl at the edges, has occlusive properties, cant see under

MUST BE ON FOR MULTIPLE DAYS IT IS VERY STICKY

not a first choice tx

34
Q

hydrogels

A

water or glycerin based gels

maintain moist environment, facilitate autolytic debridement

35
Q

hydrogel pros vs cons

A

pro- soothing and reduce pain, fill in dead space, absorb min to mod drainage, easy to apply, use to keep tendons and tissues moist

con- not for heavy exudate, dehydrate if not covered, may be difficult to secure, may cause maceration

36
Q

Hypertonic sodium additive

A

heps promote autolysis

37
Q

hydrogel indications

A 
pressure ulcers - stage 2-4
partial and full thickness wounds
radiation burns
skin tears
wounds with necrosis

must change 1-3 days

38
Q

transparent films

A

waterproof and impermeable to bacteria but allow water vapor to pass, promote moist environment

39
Q

pros and cons to transparent films

A

pro- allow wound observation, dont require a secondary dressing

con- not for infection, doesn’t absorb, not for frail skin, difficult to handle, dislodge with friction

40
Q

disadvantages to transparent films

A

nonabsorbant

may cause maceration

may cause dermal stripping

41
Q

wound fillers

A

come as paste, beads, and gels

provide moist environment, absorb exudate, debride and soften eschar

42
Q

pros and cons of wound fillers

A

-pro- fill dead space, may absorb, easy to use, use with other products

cons- not for dry wounds, need secondary dressing - usually for smaller wounds like drain sites

43
