Burns
Etiology:
Fire, chemical, electrical
Assessment of burn:
– Degree (1st, 2nd, 3rd)
– % body surface area (Rule of 9’s) 
– Parklands formula (calculation for fluid administration)
Pathophysiology:
Heat disturbs protein 3D structure → dysfunctional proteins
Disruption of skin sensation
Tissue/endothelial injury and inflammation
Increased capillary permeability → edema
Loss of water and plasma causing dehydration
Electrolytes imbalance → lose everything from intravascular space
Hypovolemia, multiorgan damage 
Rule of nines
Method for estimating percentage of body surface area impacted by burn
Clinical manifestations:
Edema
Manifestations of dehydration
Manifestations of hypovolemia
Organ failure
Death results from dehydration, poor organ perfusion and renal failure
