1. 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

3. The skin

4. Superficial erythema Only the epidermis involved Red Painful
Technically not a burn
Not included in total body surface area calculations
No complications

5. Deep & superficial partial thickness
Red with clear blisters
Deep partial thickness
Red and white with bloody blisters
Complications can include infections, scarring and contractions

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
Scarring, contractures and in the worst case scenario amputation particularly with fourth degree burns

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
The borders of the zones are not static and can be affected by factors such as hypovolaemia, hypotension and infection.
The zone of coagulation can be extended by excessive oedema therefore increasing the area of necrosis
