BURNS 1

BURNS

1.  Intact human skin must be looked upon as a highly efficient

FUNCTIONING organ of the human body.

The complete unbroken skin envelop is ascribed four main

functions:

1.1   It is capable of maintaining the internal environment

      through limiting the loss of water and electrolytes from

      the body surface.

1.2   Provides very efficient barriers to invasion by bacteria on

      its surface and in the surrounding atmosphere.

1.3   It provides an efficient apparatus for maintenance of body

      temperature, both through direct radiation of heat through

      the vast vascular bed in the skin, and through evaporation of

      sweat from the surface of the skin.       

1.4   Through its vast surface sensory nerve network, provides  

      an apparatus for detecting injurious agents and withdrawing

      the part from their vicinity.

2.  A  burn is a combination of dis-integrative,and copulative

necrosis of skin, and deeper structures, brought about by  any  of

the causes listed below:

THERMAL

   a)  Dry heat (open fire)

   b)  Moist heat (steam + hot liquids)

   CHEMICALS (ACIDS + ALKALIES)

   ELECTRIC BURNS (TOUCHING LIVE ELECTRIC WIRES)

   FLASH BURNS (HIGH TEMPERATURE SHORT DURATION)

   LIGHTNING.

   ULTRA VIOLET RAYS.
