Types of Burns: Flashcards

Study Notes

Types of Burns

Burns result from fire, heat, chemicals, radiation, or electricity, causing pain, disfigurement, psychological issues, and potentially death.
Classifications of burns include first-degree, second-degree, and third-degree.
Burns can also be categorized by extent and severity.

Thermal Burns

Most common type of burn, often resulting from house fires, car accidents, or careless handling of fire.
Caused by contact with scalding water, hot objects (e.g., irons, stoves), and sun exposure.

Chemical Burns

Result from skin contact or inhalation of acids or alkalis.
Precautions are necessary for individuals handling harmful chemicals to avoid serious injuries.

Electrical Burns

Caused by faulty wiring, chewing electrical cords, high-voltage lines, or lightning strikes.
Treatment is contingent on whether the patient can be safely separated from the electrical source.

First-Degree Burns (Superficial Burns)

The mildest burn affecting only the epidermis (outer skin layer).
Symptoms include red, dry skin, mild swelling, and pain, typically healing in 5-6 days without scarring.
Common causes include sunburn and brief contact with hot surfaces or weak acids.

Second-Degree Burns (Partial-Thickness Burns)

Affect both the epidermis and dermis layers of the skin.
Symptoms include blisters, swelling, and wet skin appearance; healing takes 3 to 4 weeks.
Caused by boiling liquids, fire, extreme sunburn, and radiation exposure.

Vesicle

A small fluid-filled sac, commonly seen as a blister associated with burns.

Mottled

Describes skin that has spots or blotches of different colors, often indicative of burn damage.

Radiation

Emission of rays from sources like x-rays and radium, can cause radiation burns.

Third-Degree Burns (Full-Thickness Burns)

The most severe type, affecting all skin layers and potentially underlying tissues, muscles, and bones.
Symptoms include skin that appears white or charred; causes include prolonged contact with hot surfaces and extensive exposure to flames.

Tissue

Formed when similar cells group together to perform specific functions in the body.

Skin Graft

Surgical procedure where healthy skin is transplanted to cover damaged areas, essential for healing severe burns.

Shock (Hypoperfusion)

Refers to a significant decrease in blood flow, affecting vital organs such as the brain and heart, often resulting from severe injuries or burns.
