The anatomy of the skin, depth of burns and
Jackson burn wound model

• JAHD Presentation
• Perry Crofts

2
The skin

• The largest organ in the body
• Consists of the epidermis and dermis
• Epidermis is the outer layer of stratified
  squamous epithelium. It is avascular and varies
  in thickness
• The dermis is a dense bed of vascular connective
  tissue
• Functions as a physical barrier and a sensory and
  thermoregulatory organ

The skin
4
Superficial erythema

• Only the epidermis involved
• Red
• Painful
• Technically not a burn
• Not included in total body surface area
  calculations

5
Deep superficial partial thickness

• Superficial partial thickness
• Red with clear blisters

• Deep partial thickness
• Red and white with bloody blisters

6
Full thickness and Fourth degree burns

• Full thickness burns
• Extend through entire dermis (full thickness)
• Stiff, white and brown
• Painless

• Fourth Degree burns
• Extends through entire skin and into underlying
  tissue
• Black and charred
• Painless

7
Jackson burn wound model

• Considers the effect of secondary injury on burns
• Zone of coagulation is central, this tissue is
  most severely damaged and lost
• Outside is the zone of stasis which can
  potentially recover
• Most periphery is the zone of hyperaemia
