The basic concept behind moist wound healing is that the
presence of exudate in a wound will provide an environment that
stimulates healing. Exudate contains various components,
including: lysosomal enzymes, WBC's, lymphokines and growth
factors. Many of the advanced dressings available to you are
designed to keep the wound bed moist with exudate.
There are clinical studies which have shown that wounds kept
in a moist environment have lower infection rates than wounds
treated with agents that tend to dry the wound bed.
The concept of 'moist wound healing' has been with us since
the 1960s, but only in the last few years has it become the
accepted treatment philosophy for chronic wound care. If
you are still treating wounds with wet-to-dry protocols, I would
urge you to contact other wound care clinicians who are using
'moist wound healing' techniques, and compare outcomes.
The most successful outcome is one that produces wound closure
in the shortest amount of time, along with the fewest number of
visits. Spending a few dollars more on a dressing is
insignificant when compared to the cost of additional treatments.
