Burns

Question 1

What is the Jackson’s burn model?

Answer 1

Pathophysiology of a burn wound

• Zone of coagulation= nearest the heat source is the primary injury → irreversible tissue necrosis at the centre of the burn due to exposure to heat, chemicals or electricity
• Zone of ischemia / stasis = reduction in the dermal circulation with potentially viable tissue → may progress to full necrosis unless the ischemia is reversed
• Zone of hyperaemia = reversible increase in blood flow and inflammation

Question 2

What is the Zone of 9’s rule in terms of burn injury?

Answer 2

• 10-15% TBSA requires fluid resuscitation → Parkland’s formula is used to calculate fluid resuscitation

Question 3

What is the management of burns injury?

Answer 3

• Radiant heaters → help to clotting cascade not be inhibited by persistent hypothermia - inhibits F9 and 10
• Cover for potential toxic shock syndrome
  
  • Ceftriaxone + Clindamycin
