Q

Head and neck: 9%
Each forelimb: 9%
Each hindlimb: 18%
Dorsal half: 18%
Ventral half: 18%
2
Q
What is the inflammatory response to burns
A
Response characterized by vasodilation, increased capillary permeability, edema, and influx of inflammatory cells.
3
Q
What is responsible for marked vasodilation within a burn wound and what is its MOA
A
Nitric oxide: direct effects on vascular smooth muscle and indirectly by stimulation of release of other vasodilatory cytokines (i.e. substance P)
4
Q
Why do burn wounds heal slower than other wounds
A
Lower concentrations of cytokines (fibroblast growth factor-2) and no endothelial chemotactic or proliferative activity is seen.
