Moisture Balance

a moist wound environment is known to encourage healing by promoting granulation and encouraging debridement by autolysis.
9. However, moisture balance must be maintained to prevent the wound bed becoming too dry or too moist, both of which could contribute to a delay in wound healing.

Dressing selection should ensure moisture balance and create an optimum environment for healing. In a chronic wound such as a DFU, the wound exudates contain enzymes which damage the healing process.  To maintain an optimal moist wound environment whilst protecting the surrounding skin from maceration, key characteristics are required.

They must absorb and retain exudate, keep harmful chronic wound exudate away from the surrounding skin, perform efficiently when used in weight bearing areas on the plantar surface of the foot, be easy to remove and be demonstrated as cost-effective. Contact dressings - to minimise disturbance to wound bed.
