Dressing Wounds

 

Wet Dressings

  • traditionally used for acute, weeping, inflammatory lesions
  • sterile or nonsterile depending on skin disorder
  • may be used to reduce inflammation by producing constriction of the blood vessel decreasing inflammation
  • cleans the skin of exudates, crusts, and scales
  • used to maintain drainage of infected areas
  • promote healing by facilitating movement of epidermal cells resulting in the formation of new granulation tissue
  • used for vesicular, bullous, pustular and ulcerative disorders as well as inflammatory conditions
  • use sterile gloves ‘
  • open wet dressings require frequent changes to prevent drying
  • closed wet dressings need less frequent changes but may cause maceration

 

Wet-to-dry dressing

  • used to remove exudate from erosions and ulcers
  • dressing remains in place as it dries
  • removed without soaking so that crusts, exudate or pus from the skin lesion adhere to the dressing and are removed with it

 

Moisture Retention Dressings

  • moist wound healing results in 40% faster wound healing
  • dressings may be impregnated with
  1. saline
  2. petroleum
  3. zinc-saline
  4. hydrogel
  5. antimicrobial agents

 

Advantages:

  1. reduced pain
  2. decreased infections
  3. decreased scar tissue
  4. gently autolytic debridement
  5. decreased dressing change frequency

 

moist dressings remain in place for 12-24h

Hydrogels

  • polymers with a 90%-95% water content
  • sheets or tube of gel
  • ideal of autolytic debridement
  • uses:
  1. for superficial wounds with high serous output
  2. abrasions
  3. skin grafts
  4. draining venous ulcers

 

Hydrocolloids

  • water impermeable
  • polyurethane outer covering
  • adherent and nonpermiable to water, oxygen and vapour
  • dressing absorbs exudate and discolors proportionately
  • moisture allows it to be removed without damaging the wound
  • product is foul-smelling yellowish colour, not to be confused with purulent drainage

 

used in :

exudative wounds nad acute wounds

left for 7 days

not need to be removed for bathing

Foam dressings

  • consist a hydrophilic wound covering surface with a hydrophobic covering
  • useful for exudative wounds and bony prominences
  • used in areas where tissue os quite irritated or macerated
  • alginate forms moist pocket over wound
