Burns

There are injuries of the skin or other tissues provoked by the thermal, radioactive, chemical or electrical contact

[pic 1]

Termal burns

There are for consequence of the application of any heat source like flames,liquid solid objects or gases

Burns for radiation

• They are caused by consequence of an exhibition prolonged to the solar ultraviolet radiation (solar burn) or artificial sources of ultraviolet radiation like solar beds or x-rays

Chemical Burns

• These are a consequence of strong acids, strong alkalis (lye or cement), phenols, cresoles, gas mustard or phosphorus. The necrosis of the skin or tissues can continue several hours.

Electrical burns

These are a consequence of the electrical generation of heat and they can provoke extensive damage in the deep tissues although the cutaneous injury seemingly is minimal.

Clasification

They qualify according to its depth:

• The first grade
• Partial thickness (the second grade)
• Finished thickness (third grade)

[pic 2]

The first grade

They only affect  the epidermis.

[pic 3]

Burns of partial thickness

• They affect part of the corium and split in:
• Superficial: they affect top half of the corium, recover from 2 until 3 weeks only they leave scar if they become infected.
• Deep: they affect low half of the corium, take more than 3 weeks in recovering and leave scar even without infection.

Burns of entire thickness

• They spread across the whole corium and affect underlying greasy wing.
• The healing takes place only from the periphery and normally they need a skin grafting

Signs and symptoms

• Pain 
• Burning  
• Sensibility 
• Fibrinuous exudation.
