| 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 |
*When the overlying skin is necrotic, the staging cannot be accurate until debridement is performed.
