A specific type of wound caused by a thermal agent.
Range of Severity?
Mild redness to full thickness tissue destruction of dermis + deeper tissues.
What factors are considered when assessing severity?
Depth, Amount of tissue affected, Area of burn, Cause of burn, Age of person, pre-existing conditions.
Define Superficial Burns
1st Degree, affecting epidermis only. Redness and pain, mild localized edema. Healing is rapid w/ no scar tissue. Possible discoloration of skin.
Define Partial-thickness burns
2nd Degree, affecting epidermis/dermis. Presence of Blistering! Can be superficial/deep. The deeper the burn the higher the risk of infection/edema and reduced pain. Superficial- 14-21 day heal time. Deep- 21-35 day heal time. Risk of fibrosis, contacture and loss of ROM.
Define Full-thickness burns
3rd + 4th Degree. Affecting all layers of tissue layers and possibly deeper underlying tissues. Substantial damage to all structures, may appear dry and inelastic/white and wavy/charred. Painless due to nerve damage. Re-epithelialization possible, skin grafts required.
Define the rule of 9's.
Percentage of the body surface damaged by the burn calculated by predetermined 'map', Approximates only.
