All The Classification of Burns

What is Burn?

A burn is an injury to the skein or other organic tissue primarily caused by heat or due to radiation, radioactivity, electricity, friction, or contact with chemicals. Skin injuries caused due to radioactivity, ultraviolet radiation, electricity, or chemicals as well as respiratory damage resulting from smoke inhalation are also known as burns.

Damage to the skin or other body parts is caused by extreme heat, flame, and contact with heated objects or chemicals. Burn depth is general y categorized as a first, second, or third degree. The burn may be painful and may cause redness or peeling skin, blisters, swelling, and white or charred skin.

Classification of Burns Injury:

Burn is classified according to the different categories which are presented below:

According to Cause:

It includes-

1. Thermal Burn:
It is caused by conduction or convection. Example: hot liquid, fire or steam, etc.
2. Electrical Burn:
It is caused by the passage of electrical current through the body. There is generally an exit and entrance wound.
3. Chemically Burn:
It occurs when certain chemical compounds come in contact with the body. Example: Sulphuric acid, lye, hydrochloric acid, gasoline, etc.


According to Zone or Extent:

It includes-

1. Zone of Coagulation:
Branch of greatest destruction, tissue necrosis, immutable cell damage.
2. Zone of Stasis:
Harmed tissue, the area of less severe injury which possesses reversible damage and surrounds the zone of coagulation.
3. Zone of Hyperemia:
Pink, no cell depth, the area surrounding the zone of stasis that presents with inflammation but willfully any interventions or permanent damage.


According to the Depth of Tissue Damage:


a. Traditional:

It includes-

1. First Degree:
It includes only the outer layer of skin, the epidermis. Skin is usually red and very painful.

2. Second degree:
This type of burns involves the epidermis and part of the dermis layer of the skin. The second-degree burn site appears blistered, red, and maybe swollen and painful.

3. Third Degree:
All layers of the skin are destroyed. It extends into the subcutaneous tissues.

4. Fourth Degree:
It is the same as a third-degree but with damage to deeper structures such as tendons, joints, and bone.

b. Modern Terminology:

It includes-

1. Superficial:
It involves only the outer epidermis, heals without scarring.

2. Superficial Partial-Thickness:
It involves the epidermis & the supper portion of the dermis, pain & blisters, heals with min to no scarring.

3. Deep- Partial-Thickness:
It completes the destruction of the epidermis & the majority of the dermis, blisters, edema; it may heal with hypertrophic scars & keloids.

4. Full-Thickness:
It completes the destruction of the epidermis & dermis along with partial damage of the subcutaneous fat layer. It requires grafts & susceptible to infection.

5. Sub-dermal:
It completes the destruction of the epidermis, dermis & subcutaneous tissue, which may involve muscle & bone. It often requires surgical intervention.
