Evaporation of the moisture decreases in hydrated atmosphere and the skin recovers along the moist surface of wound.
Therefore the recovery rate in moisture condition is faster than in the dry condition. Also, the cure of the wound is more efficient because materials contained in ooze of the wound such as polymorphonuclear leukocyte, macrophage, protease and cell growth factors can act more smoothly in hydrated atmosphere.
Types of wet dressing
Hydrogel - A mixture of water-soluble polymer and water which contains a large amount of moisture so that it creates proper hydrated atmosphere, however, it needs additional supporting body due to it's relatively low absorbency and weak adhesiveness.
Polyurethane Foam - A dressing material having high degree of water absorption and permeability. It is suitable for a cut and a burn but has drawbacks that there is no self-adhesiveness and it is opaque preventing observation of the wound.
Hydrocolloid is a compound of hydrophile and hydrophobic polymers mixes together to have appropriate absorption and superior adhesion providing moisture atmosphere to the wound and these properties give the wound a better cure.
Semitransparent material allows you monitoring and a better care of the wound with the dressing applied on the wound.
