Burn Classification | The extent and severity of a burn is dependent on gender, age, duration of burn, type of burn, and affected area. Burns are most appropriately classified according to the depth of tissue destruction. |
Superficial Burn: | involves only the outer epidermis. The involved area may be red with slight edema. Healing occurs without evidence of scarring. |
Superficial Partial-Thickness Burn: | involves the epidermis and the upper portion of the dermis. The involved area may be extremely painful and exhibit blisters. Healing occurs with minimal to no scarring. |
Deep Partial-Thickness Burn: | burn involves complete destruction of the epidermis and the majority of the dermis. The involved area may appear to be discolored with broken blisters and edema. |
Full-Thickness Burn: | involves complete destruction of the epidermis and dermis along with partial damage of the subcutaneous fat layer. The involved area often presents with eschar formation and minimal pain. Patients with full-thickness burns require gr |
Subdermal Burn: | involves the complete destruction of the epidermis, dermis, and subcutaneous tissue. Subdermal burns may involve muscle and bone and as a result often require surgical intervention. |
Full-Thickness Burn | Burn causes immediate cellular and tissue death and subsequent vascular destruction |
Full-Thickness Burn | Eschar forms from necrotic cells and creates a dry and hard layer that requires debridement |
Full-Thickness Burn | Absent sensation and pain due to destruction of free nerve endings, however, there may be pain from adjacent areas that experience partial-thickness burns |
Deep Partial-Thickness Burn: | Damage to nerve endings may result in only moderate levels of pain. Healing occurs with hypertrophic scars and keloids. |
