Burn injury insulin resistance and central nervous system complications: A review
Insulin resistance is a major underlying and preexisting event in chronic metabolic disorders. However, this is also an acute, de novo condition in critical burn survivors and other emergency episodes. Irrespective to its proximal trigger in burn pathology, peripheral insulin resistance results from...

Insulin resistance is a major underlying and preexisting event in chronic metabolic disorders.
