22
Q

P/Contraindications:
-heavily draining wounds -infected wounds
-caution on immunocompromised patients – can promote anaerobic bacterial growth.
-dry wounds, arterial ulcers, 3rd deg burns, or wounds with min drainage
-wounds with exposed tendons/fascia
Should only be used on: patients with good border skin integrity

A

Hydrocolloids

23
Q

Salts are extracted from brown seaweed and converted into Ca/Na salts.
React with serum and wound exudate to form a hydrophilic gel to provide a moist wound environment
Highly permeable and nonocclusive, requires secondary dressing

A

Alginates

24
Q

Alginates: Available in 3 forms

A

Sheets (to absorb drainage)
Ropes ( to fill tunnels, cavities, or undermining)
Alginate-tipped applicators (to probe wounds, perform swab cultures, and to measure wound depth)

25
Q 
Common Uses:
-Absorbs 20x their weight in exudate.
-Mod to highly draining wounds.
-P-T and full-T draining wounds.
-infected wounds
(Dressings must be changed daily; Skin sealant should be used
A

Alginates

26
Q

P/Contraindications:

  • 3rd deg burns (F-T).
  • wounds with exposed tendon, joint capsule, or bone
  • neonates (causes electrolyte imbalances).
  • dry or min draining wounds
A

Alginates

27
Q

Multilayer dressings that can be used as primary or secondary dressings

A

Composite Dressings

28
Q

Composite Dressings: 3 layers?

A

-Inner contact layer: nonadherent, prevents trauma.
-Middle layer: absorbs moisture to prevent maceration yet maintains moist wound bed
(May consist of hydrogel, semipermeable foam, hydrocolloid, or alginate).
-Outer layer: serves as bacterial barrier (Commonly a semipermeable film)

29
Q
  • Antiseptic agent incorporated into all classes of dressings.
  • Release of ions in the wound bed result in a blue-black.
  • limited research to support it is effective against multiple organisms within a wound or against biofilms.
  • Saline cannot be used because it deactivates it.
A

Silver Dressings

30
Q

Free ____release should be ___ mg/l to have the best results. (effective!)

A

silver; >20

31
Q
  • caution in use with epithelializing or granulating wounds (cytotoxicity).
  • No evidence that it helps prophylactically in healing uninfected wounds
  • cost more than standard moisture-retentive dressings
  • Don’t use on neonates due to toxicity
A

Silver Dressings

32
Q
  • Key function: control odor by absorbing odor-producing gases released by bacteria.
  • Dressings do not enhance wound healing rates more than any other type of moisture-retentive dressing
A

Charcoal dressings

33
Q 
Benefits:
Antimicrobial (acidic)
Reduces pain
Stimulates proliferative phase
Reduces edema
A

Honey

34
Q
  • May facilitate wound healing
  • Bovine has been incorporated into sheets, ropes, wound dressings, and topical agents such as gels or particles
  • It adheres to wound bed but not to periwound.
  • may be used on both infected and uninfected wounds including superficial burns and donor sites.
  • left in place until the wound is resurfaced underneath
A

Q

Generally alcohol-based wipes are used on intact periwound skin.
Makes skin tacky for a better edge seal and protects skin from adhesive.

Extremely costly and limited to chronic wounds that are recalcitrant to traditional interventions

A

Growth Factors: cytokines, interleukins, colony-stimulating factors

41
Q

If _____ is indicated, a moisture-retentive dressing should be selected and should remain in place for several days

A

autolytic debridement

42
Q

If _____is indicated, gauze is appropriate with dressing changes 1–3 times per/day

A

enzymatic debridement

43
Q

If ____is desired, a wet-to-dry or other similar technique should be selected.

A

mechanical debridement

44
Q

Granular and Nondraining

A

Wound healing as expected.

Moisture may need to be added with hydrogel or a more occlusive dressing should be used

45
Q

Granular and Draining

A

Granulation tissue and periwound should be protected.

A more absorptive dressing should be applied.

If heavily draining, infection may be present.

46
Q

Necrotic and nondraining

A

Requires debridement and softening of eschar.

Moisture may need to be added.

Enzymatic debridement.

Surrounding tissue should be protected with a skin sealant

47
Q

Necrotic and Draining

A

Requires debridement, absorption, and protection of surrounding tissue.
Wound should be observed for S&S of infection.
