burns

burns

1. is a type of injury to skin or other tissues

   • caused by
     • heat
     • cold
     • friction
     • chemicals
     • electricity

2. skin

   • structure
     • epiderms
     • dermis
     • subcuatanous
   • function
     • protection
     • sensation
     • absorbtion
     • lubrication
     • storage

3. degree

   • third degree
     • all the layers are included
   • second degree
     • epidermis and half of the dermis
   • first degree
     • epiderms

4. percentage

   • rules of nine
     • the rule of nines is a standardized method used to quickly assess how much body surface area has been burneed on a pateint
     • applied only in 3 degree and 2 degree
   • the palm method
     • small or patchy burns can be approximated by using the surface area of the pateint's palm
     • 1 palm = 0.5% no fingers
     • 1palm =1% with fingers

5. FIRST AID

   • STOP the burning process
     • COOL with running water
       • COVER the burn

6. necrosis VS apoptosis

   • necrosis
     • is cell death that is tiggered by external factors or disease such as trauma or infection . is alwaysabnormal and harmful
     • causes acute inflammation
       • is an immediate response of a vascularized tissue to injury
         • arises in response to
           • infections
           • tissue necrosis
           • forign body
         • local signs
           • redness
           • swelling
           • pain
           • impaied movement
   • apoptosis
     • is a form of cell death that is generally triggerd by normal ,healthy processes in the body . which can also occur as a defense mechanism during healing process. it is normal
     • no inflammation

7. antibiotics

   • drugs that prevent themultiplying of microorganism
     • mode of action
       • cidal
       • static
     • spectrum of action
       • wide
       • narrow

8. tissue repair

   • tissue regeneration
   • fibrosis tissue
   • depends on
     • severity of injury
     • proliferative capacity of the tissue

9. complications of wound healing

   • shock
   • excessive contraction
   • infection
   • indequate scar formation
