Abstract
The present invention provides a wound dressing in the form of a gauze or similar absorbent material having a partially or substantially dehydrated hydrogel material impregnated therein for absorbing wound exudate. The wound dressing is capable of absorbing large amounts of wound exudate without inhibiting the healing of the wound to which it is contacted and without the need for additional backing or adhesive layers. The wound dressing also has a pliable, soft structure which permits the dressing to be applied to wounds having irregular shapes and depths.
