Foam Dressing

fine foam

coarse foam

Description

- polyurethane foams with pores in variable sizes,
- some with semiocclusive outer layers (protects clothes),
- some with contact layers towards the wound (silicone, hydrocolloid)
- compression changes structutre of foam, reduces water uptake

fine foam:
- high water uptake, different moisture vapor tramsmission rates (MVTR),
- poor uptake of exudate, less wound adhesion, less pain

coarse foam:
- higher uptake of exsudate, reduction of slough
caution: ingrowth and adhesion may cause pain on removal (soak well)


Indications

- moderate to heavier exudation
- contact layers on sensitive wounds (e.g. split skin donor site)
- assistance on autolytic debridement (coarse foams)
- environment for healing (damp, warm, protected)


Limitations

- edge maceration (due to horizontal transport of exudate)
- infection (more frequent change of dressing)
- PAD grade IV
- pain on removal (coarse foam)


Notes

- overlap wound edge well
- achieve contact to wound bed, by filling
- some are self adhesive
- some need additional fixation by bandage or foils
caution: additional foil coverage reduces gas permeability of semiocclusive foams, just cover the edges of the dressing with strips of foil for attachment


Change of dressing

- change before edge is reached (beware of maceration)
- on demand every 2 to 7 days
