Ans- Second-degree burns involve the epidermis and part of the lower layer of skin, the dermis. The burn site looks red, blistered, and may be swollen and painful. Third-degree (full thickness) burns. Third-degree burns destroy the epidermis and dermis. Second-degree burns (partial thickness burns) affect the epidermis and the dermis (lower layer of skin). They cause pain, redness, swelling, and blistering. Third-degree burns (full thickness burns) go through the dermis and affect deeper tissues. They result in white or blackened, charred skin that may be numb.
Second degree burns are also called partial thickness burns. This type of burn damages the epidermis and the dermis. The dermis is the second layer of skin. Second degree burns are painful. The injured area can swell and appear red with blisters. The damaged skin usually grows back unless it becomes infected or the injury gets deeper.
Third degree burns are also called full thickness burns. This type of burn goes through the epidermis and dermis and affects deeper tissues, which may also be damaged or destroyed. The injured area can appear charred and may be black, white, or deep red in color. This area is often numb to light touch. Third degree burns don’t heal by themselves, so skin grafting is often necessary .
Burn injuries can happen in many ways. Common examples are:
Parkland formula = (m) is in kilograms (kg), area (A) as a percentage of total body surface area, and volume (V) is in milliliters (mL).
V= 4.m.(A.100)
V= 4 ×23 × 50× 100
V= 460,000 ml
