Abstract
A pressure ulcer at the sacral area often shows a cavity under the skin known as a pocket. The treatment for the pressure ulcer with a pocket is very difficult. At first we tried to treat them in accordance with wound healing principles but then,we established particular treatment methods.
First the wound was debrided and then covered with healthy granulation tissue. Using a hydrocolloid dressing directly adhering to both sides pocket surface was made. The histological examination of the adhered area showed poor vascularization,and was very fragile with less fibroblast containing granulation tissue. The adhesion,when being kept quiet,soon became stronger. If it is difficult to keep the wound quiet or if the wound is diagnosed as infected,the pocket must be opened as soon as possible.
At all events it is essential to keep the wound in a moist environment and to avoid using antiseptics on it.
