-Injury to epidermis
-Mild to severe erythema but no blisters
-skin blanches with pressure
-painful, tingling sensation, eased with cooling
-healing occurs in 3-6days
-no scarring occurs


Describe a Superficial Partial-Thickness Burn

-injury into the dermis, blood supply is reduced
-large blisters
-edema present
-mottled pink to red base & broken epidermis, w/wet,shiny, and weeping surface
-painful and sensitive to cold air
-heals in 10-21 days
-no scarring
-may require grafting


Describe a Deep Partial-Thickness Burn

-extends deep into skin dermis
-usually no blisters
-wound surface is red and dry with white areas in deeper parts
-edema present and may or may not blanch
-watch for ischemia, infection, or hypoxia: can convert to full thickness burns


Describe a Full-Thickness Burn

-Injury and destruction of epidermis and dermis
-grafting may be required
-dry, hard, leathery eschar
-appears waxy white, deep red, yellow, brown, or black & a dry surface appearance
-sensation reduced or absent
-Healing may take weeks to months
-requires removal of eschar and split or full skin grafting
-scarring and wound contractures are likely


Describe a Deep Full-Thickness Burn

-injury extends beyond the skin into the underlying fascia and tissues, and muscle, bone & tendons
-appears black & sensation is completely absent
-eschar is hard and inelastic
-no pain cause nerve endings are destroyed
-healing takes months and grafts are required
