Q

What are the mechanisms of action and benefits of negative pressure wound therapy?

A
• Removal of exudate
• Moist wound environment
• Decrease bacterial burden
• Reduce edema and excess interstitial fluid
  - Increases blood flow
• Increase in microvascular blood flow
• Stimulation of granulation tissue
  - Mechanical deformation
• Promotes wound contraction
• Reduces dressing change frequency

Q

What are the general equipments used in negative pressure wound therapy?

A

• Pump provides suction
- Electric, battery
- Reusable, disposable; large, portable, tiny
• Wound filler or cover transfer pressure across wound bed &
allow fluid to move through & into canister
• Tubing – delivers suction, transports fluids
• Canister – holds evacuated fluids
• Occlusive sheeting provides air-tight seal
- Maintain sub-atmospheric pressure
• Application – simple to complicated

Q

What are the precautions to take for negative pressure wound therapy?

A
  • Anticoagulants, low platelet count
  • Non-enteric & unexplored fistulas
  • Over named structures (bone, tendon, organs, vessels, etc.)
  • Requires several layers of barrier dressing or use of white foam
  • Monitor for bleeding
  • Avoid circumferential occlusive sheeting application due to increased risk of ischemia
  • Monitor skin condition when placed over bony prominences or prominent hardware due to compression
  • Sharp edges of exposed bone should be debrided prior to application to protect soft tissue during compression
  • MD notified if drainage in canister is sanguineous, fills w/n 1 hour, or if >2 canisters filled w/n 24 hrs

Q

What are the precautions to take for negative pressure wound therapy in regards to arterial insuffuciency?

A

AI (not for moderate/severe AI)
• Compression at wound edge causes 1-2.5 cm area of hypoperfusion
- Not a good idea for AI wounds where surrounding tissue is already
compromised
- Use lower pressures
- Intermittent mode - if appropriate

Q

What are the methods to help reduce pain at the dressing change of negative pressure wound therapy?

A

• Soak wound filler 3-5 minutes w/saline - infuse via tubing
• Protective layer – prevents adherence to fragile tissues

• Pull occlusive sheeting parallel to the skin
• Skin protectant
• Frequent dressing change (24 verses 48 hours)
• Granulation ingrowth less likely w/gauze
- Greater compression/contraction w/foam compared, less pain
• Pain/discomfort at initial pressure application may last 20 minutes
• White foam may be less painful upon removal vs black foam
• Calcium alginate under foam may reduce removal pain
• At dressing change, cover tissue w/soak to prevent dehydration
• Pain meds prior to dressing change

• Mild occlusiveness, promotes moist wound healing
• Less permeable then “regular” gauze (fluid held underneath)
• Can be combined with topicals
• Can be primary or secondary (requires coverage)
• Some can be left in place several days
• Typically used on wounds w/o a lot of depth
- Some used to protect deeper named structures
• Ex: Adaptic, Xeroform

88
Q

What are the cautions to take when using an impregnated gauze?

A

Maceration, adherent if allowed to dry

89
Q

What are the characteristics of a semipermeable film dressing?

A

• Thin, flexible, multiple sizes, cut to size
• Transparent, occlusive (promotes autolytic debridement)
• Barrier to outside world, can stay in place up to 7 days
• Little absorption if used alone, can be combined w/other dressings
• Primary or secondary dressing
• Usually for more superficial wounds
- Requires primary dressing for cavity/deep wounds
• Highly conformable, adherent to peri-wound/surrounding skin

90
Q

What are the cautions to take when using a semipermeable film dressing?

A

Limit wrinkles, applied w/o tension, difficult to apply, not

water proof, specific removal technique, damage skin w/removal

91
Q

What are the characteristics of a hydrogel dressing?

A
• Donate moisture
- Can absorb small amounts of drainage
- Decrease pain
- Promote autolytic debridement
• Gel & sheet forms
• Can be combined w/other dressings
- Silver powder + hydrogel = silver gel
- Regular gauze + saline + hydrogel = moist dressing
- Mush into nu-gauze for easy wound filling – but adds moisture
• Requires secondary dressing
92
Q

What are the cautions to take when using a hydrogel dressing?

A

Maceration, sheets not used on infected wounds

93
Q

What are the characteristics of a foam dressing?

A

• Absorptive
- Can be used with most thicker topicals (ointments)
• Flexible, variety of sizes, cut to size
• Non-adherent, thick & thin
• Primary or secondary dressing
- Padding, additional absorption
- Can be combined w/other dressings (layered over primary dressing)
• Insulating
- Promote autolytic debridement
• Can be left in place up to 7 days

94
Q

What are the cautions to take when using a foam dressing?

A

Maceration, can roll w/friction

95
Q

What are the characteristics of a hydrocolloids dressing?

A

• Highly occlusive
- Promote autolytic debridement
• Highly adhesive
• Sheets: various sizes, cut to fit, thick & thin
• Paste: can be used for deeper wounds
• Primary or secondary dressing (usually as primary)

96
Q

What are the cautions to take when using a hydrocolloids dressing?

A

Maceration (not as absorbent as some say), skin damage
w/removal, sheet forms not for deep wnds, paste/particles
expand in deeper wnds, edges can roll w/friction, linked
w/hypergranulation

97
Q

What are the characteristics of an alginate dressing?

A

• Highly absorptive
- Hold drainage in dressing, absorb vertically/laterally
- Gel w/absorption for atraumatic removal, may trap bacteria w/n dressing,
• Some assist w/clotting
• Sheet & rope, various sizes, cut/tear to fit
• Frequently combined in or w/other dressings
• Can be left in place up to 7 days
• Non-occlusive
• Contour easily to wound surfaces, can be layered into deeper wounds

98
Q

What are the cautions to take when using an alginate dressing?

A

Maceration if placed outside of wound margins, for highly draining wounds, wound desiccation, look “bad” when wet

99
Q

What are the contraindications of an alginate dressing?

A

Not to be used over bone, tendon, etc. or on neonates (<38wks gestation

100
Q

What are the characteristics of a hydrofiber dressing?

A

• Highly absorptive (more than alginate)
• Absorb vertically (less risk of maceration vs alginate)
• Different sizes, cut to size
- Sheets
• Aquacel (ConvaTec)
- New wound ribbon dressing
- “stitchbonding” to increase strength

101
Q

When should an antimicrobial dressing be used?

A
  • Critical colonization (trial ~ 2 wks)
  • Active infection
  • High risk of infection
102
Q

When should an antimicrobial dressing be discontinued?

A
  • Clean wound, epithelializing/granulating
  • Risk is removed
  • Short term dressings – clear reason to use them, know when to stop
103
Q

What are some examples of an antimicrobial dressing?

A
  • Cadexomer Iodine
  • Silver
  • Honey
104
Q

What are the characteristics of a cadexomer iodine dressing?

A

• Broad spectrum antimicrobial
- Slow release of iodine, non-cytotoxic
• Absorptive
- Turns white w/absorption
• Various forms
• Can be cheaper than others depending on dressing frequency
• Can stain skin, cannot combo w/collagenase

105
Q

What are the cautions to take when using a cadexomer iodine dressing?

A

Allergy to iodine/shellfish, pregnancy/breast feeding, < 6

months old, widespread prolonged use (hyperthyroidism/cytotoxicity)

106
Q

What are the contraindications of a cadexomer iodine dressing?

A

Thyroid disease, deep cavity wounds

107
Q

What are the characteristics of a silver dressing?

A

• Broad spectrum
• Various forms (combined w/other dressings)
- Powder, gel, alginate, hydrocolloid, foam, sheets, creams, etc.
• Various wear times: daily – 7 days (Depending on method of release)
• SSD (Silvadene, Silversulfadiazine)
- Cream must be thoroughly removed daily
