Flashcards in Wound Dressings (Lab Info--Teri) Deck (12):
1

Alginates

-made from seaweed
-sheets/ropes
-absorb exudate
-infection
-non-adherent
-require secondary dressing
-hydrofibers (alternative; absorb 30% more)

2

Bioengineered Tissue

-Apligraph: from neonatal foreskin in bovine collagen matrix
-dermagraft: from human fibroblasts (cryopreserved dermal substitute)
-proteins/cytokines stimulate wound healing
-only on clean, debrided, non-infected wound
-diabetic ulcers

3

Collagens

-cowhid/tendon, chicken tendon
-recognized by tissue cells
-accelerate wound repair by providing collagen matrix for cellular migration

4

Contact Layer Dressing

-fenestrated: drainage out, medications in
-cling to skin w/o adhesive
-gauze pads w/ non-adherent surface

5

Transparent Film

-won't stick to moist wound bed
-superficial wounds
-impermeable to water and bacteria
-autolytic debridement
-protect from shear

6

Foam Dressing

-heavily exuding wound/chronic wound
-wick away moisture
-beneath compressive dressing
-autolysis
0thermal and protective properties
-can use with infection

7

Gauze Dressings

-wick and absorb drainage
-may stick to wound bed as it dries

8

Hydrocolloid Dressings

-adherent
-difficult anatomical areas (elbow, heel, ear)
-chronic wounds and burns
-autolytic debridement
-thermal protection
-not with infection

9

Hydrogels

-maintain moisture
-not good bacterial barrier
-cooling effect for pain/anti-inflam
-partial thickness burns, donor sites, chronic wounds
-non-adherent (need 2* dressing)
-autolytic debridement
-potential for maceration

10

Anti-microbial dressings

-silver: 3-7 days/dressing (MRSA, VRE)
-cadexomer iodine: 72 hours, (MRSA, VRE)
-Cytotoxic topical antimicrobials (cytotoxic to all cells including healthy cells)

11

Skin/Wound Cleansers

-ingredients help loosen debris and foreign matter from wounds
-not harmful to good tissue

12

Skin Sealants/Protective Barriers

-protect skin surface with sealant film
-provides barrier against urine/stool
-protective for intact skin
