Can you survive 80 burns?

Some publications [2,3] have suggested that survival rates reach 50% in young adults sustaining a Total Body Surface Area (TBSA) burned of 80% without inhalation injury. Recent U.S. data indicate a 69% mortality rate among patients with burns over 70% of TBSA [4].

Why burn victims die?

Sepsis is the leading cause of death after burn injury. Multiple antibiotic resistant bacteria now account for the bulk of deaths due to sepsis. Further improvement in survival may require improved strategies to deal with this problem.

Can you survive 85% burns?
