Properties of topical agents and dressing materials

Properties of topical agents and dressing materials
Type Actions Indications/use Precautions/contraindications
Alginates/CMC*
  • Absorb fluid.
  • Promote autolytic debridement.
  • Moisture control.
  • Conformability to wound bed.
  • Moderate to high exuding wounds.
  • Special cavity presentations in the form of rope or ribbon.
  • Combined presentation with silver for antimicrobial activity.
  • Do not use on dry/necrotic wounds.
  • Use with caution on friable tissue (may cause bleeding).
  • Do not pack cavity wounds tightly.
Foams
  • Absorb fluid.
  • Moisture control.
  • Conformability to wound bed.
  • Moderate to high exuding wounds.
  • Special cavity presentations in the form of strips or ribbon.
  • Low-adherent versions available for patients with fragile skin.
  • Combined presentation with silver or PHMB for antimicrobial activity.
  • Do not use on dry/necrotic wounds or those with minimal exudate.
Honey
  • Rehydrate wound bed.
  • Promote autolytic debridement.
  • Antimicrobial action.
  • Sloughy, low to moderate exuding wounds.
  • Critically colonized wounds or clinical signs of infection.
  • May cause "drawing" pain (osmotic effect).
  • Known sensitivity.
Hydrocolloids
  • Absorb fluid.
  • Promote autolytic debridement.
  • Clean, low to moderate exuding wounds.
  • Combined presentation with silver for antimicrobial activity.
  • Do not use on dry/necrotic wounds or high exuding wounds.
  • May encourage overgranulation.
  • May cause maceration.
Hydrogels
  • Rehydrate wound bed.
  • Moisture control.
  • Promote autolytic debridement.
  • Cooling.
  • Dry/low to moderate exuding wounds.
  • Combined presentation with silver for antimicrobial activity.
  • Do not use on highly exuding wounds or where anaerobic infection is suspected.
  • May cause maceration.
Iodine
  • Antimicrobial action.
  • Critically colonized wounds or clinical signs of infection.
  • Low to high exuding wounds.
  • Do not use on dry necrotic tissue.
  • Known sensitivity to iodine.
  • Short-term use recommended (risk of systemic absorption).
Low-adherent wound contact layer (silicone)
  • Protect new tissue growth.
  • Atraumatic to periwound skin.
  • Conformable to body contours.
  • Low to high exuding wounds.
  • Use as contact layer on superficial low exuding wounds.
  • May dry out if left in place for too long.
  • Known sensitivity to silicone.
PHMB
  • Antimicrobial action.
  • Low to high exuding wounds.
  • Critically colonized wounds or clinical signs of infection.
  • May require secondary dressing.
  • Do not use on dry/necrotic wounds.
  • Known sensitivity.
Odor control (eg, activated charcoal)
  • Odor absorption.
  • Malodorous wounds (due to excess exudate).
  • May require antimicrobial if due to increased bioburden.
  • Do not use on dry wounds.
Protease modulating
  • Active or passive control of wound protease levels.
  • Clean wounds that are not progressing despite correction of underlying causes, exclusion of infection, and optimal wound care.
  • Do not use on dry wounds or those with leathery eschar.
Silver
  • Antimicrobial action.
  • Critically colonized wounds or clinical signs of infection.
  • Low to high exuding wounds.
  • Combined presentation with foam and alginates/CMC for increased absorbency. Also in paste form.
  • Some may cause discoloration.
  • Known sensitivity.
  • Discontinue after 2 weeks if no improvement and reevaluate.
Polyurethane film
  • Moisture control.
  • Breathable bacterial barrier.
  • Transparent (allow visualization of wound).
  • Primary dressing over superficial low exuding wounds.
  • Secondary dressing over alginate or hydrogel for rehydration of wound bed.
  • Do not use on patients with fragile/compromised periwound skin.
  • Do not use on moderate to high exuding wounds.
Other more advanced dressings (eg, collagen and bioengineered tissue products) may be considered for wounds that are hard to heal[1].
CMC: carboxymethylcellulose; PHMB: polyhexamethylene biguanide.
* Wound dressings may contain alginates or CMC only; alginates may also be combined with CMC.
