Hair Folicle Sweat Gland Burn Depth Skin Layer 1° Epidermis Skin 2° Dermis 3° Subcutaneous 4° Tissue (FAT) Anatomy Muscle Burn Injury: First Degree Burns CHARACTERISTICS • Abnormal redness of the skin Hair Folicle • Involves only the epidermis (first layer of Sweat Gland Burn skin) Depth Skin Layer 1° Epidermis • No blistering • Mild total body effects 2° • Heals in 3 to 4 days Dermis 3° Subcutaneous 4° Tissue (FAT) Muscle Second Degree Burns CHARACTERISTICS Superficial Partial Thickness • Papillary dermis (upper portion of the second layer of skin) Hair Folicle – Affects the first layer of skin and the top Sweat Gland Burn of the second layer of skin Depth Skin Layer 1° Epidermis • Blister formation • Burn appears pink and moist 2° • Painful, very sensitive Dermis • Turns white to the touch 3° Subcutaneous • Hair usually intact 4° Tissue (FAT) Muscle • Doesn’t scar–change in skin color Second Degree Burns CHARACTERISTICS Deep Partial Thickness • Reticular dermis (lower portion of second layer of skin) Hair Folicle – Involving tissue layers underneath Sweat Gland Burn Depth Skin Layer top skin layers 1° Epidermis • Healing process more than 3 weeks • Spotted red and white 2° Dermis • Decreased pain • Doesn’t turn white to the touch 3° Subcutaneous • Hairs pluck out easily 4° Tissue (FAT) Muscle • Scarring increases • May require surgical cleaning or grafting Third & Fourth Degree Burns CHARACTERISTICS Full Thickness • Burn is into fat or deeper • Area is red, white, brown or black Hair Folicle • Not painful Sweat Gland Burn Depth Skin Layer • Area is dry or leathery 1° Epidermis • Doesn’t turn white to the touch • Heals only from the edges 2° Dermis • Almost always requires surgery 3° Subcutaneous 4° Tissue (FAT) Muscle.
