What Are the Classifications of Burns? First-degree (superficial) burns First-degree burns affect only the epidermis, or outer layer of skin. The burn site is. Second-degree - (partial thickness) burns Second-degree burns involve the epidermis and part of the dermis layer of skin.
Burn Assessment Overview. Superficial Dermal Partial Thickness Burns. These burns involve the epidermis and the superficial part of the dermis – the papillary dermis. These types of burns are very painful due to the exposure of sensory nerves. Capillary return will be brisk as vasculature is intact. First-degree burns affect only the epidermis, or outer layer of skin. The burn site is red, painful, dry, and with no blisters. Mild sunburn is an example. Long-term tissue damage is rare and usually consists of an increase or decrease in the skin color.
|Zone Name||Location||Tissue Damage||Change with Treatment|
|Stasis||Middle||Dynamic penumbra||Target of burn care: good first aid and wound management can significantly reduce the need for skin grafting (otherwise it can turn into zone of coagulation, if not properly treated)|
|Hyperemia||Outer||Reactive inflammation||Will return to normal within hours of the injury regardless of care|
