*When the overlying skin is necrotic, the staging cannot be accurate until debridement is performed.
|Stadium||Definition||Aussehen||topische Therapie||durchschnittl. Heilungszeit|
|I|| Nonblanchable erythema of intact skin||Pink skin that does not resolve when pressure is relieved; discoloration; warmth; induration||DuoDerm q2-3d||14 d|
| II|| Partial-thickness skin loss involving epidermis and/or dermis||Cracking, blistering, shallow crater, abrasion||Cleanse with saline; DuoDerm/Tegaderm dressing||45 d|
| III|| Full-thickness skin loss into subcutaneous fatty tissues or fascia||Distinct ulcer margin; deep crater (in general, 2.075 mm or deeper [the thickness of a nickel])||Debride; irrigate with saline; apply DuoDerm/Tegaderm||90 d|
| IV|| Full-thickness skin loss with extensive tissue involvement of underlying tissues||Extensive necrosis; damage to underlying supporting structures such as muscle, bone, tendon, or joint capsule||Surgically debride; irrigate with saline (possibly under pressure); apply advanced topical dressings; consider antibiotics||120 d|
