Preferred method of management for burn pts now?
early excision and grafting
AT 12-15% of O2 in the air, what toxicity symptoms does one exhibit?
muscular coordination for skilled movements lost
At 10-14% of O2 in the air, what toxicity symptoms does one exhibit?
judgement is faulty and and muscular effort leads to rapid fatigue
At 6-8 % O2 in the air, what symptoms are seen?
collapse, rapid treatment would prevent fatal outcome
Death occurs in 6-8 at what percent of oxygen?
6 or below
4 etiologies of burns?
chemical, thermal, electrical, inhalation
This degree burn involves the top layer of the epidermis only?
Characteristics of 2nd degree burn?
blisters, epidermis and dermis- may involve all of dermis
Characteristics of 3rd degree burn?

superficial dermal and deep dermal
Characteristics of a superficial dermal burn?
epidermis and upper part of dermis. heals spontaneously. red or pale ivory, moist shiny surface, painful, immediate blistering, minimal scarring
Characteristics of deep dermal burn?
deep dermis, often involves incision and grafting for repair, mottled w white waxy dry surface, may or may not have blisters, significant scarring
Characteristics of third degree burn?
full thickness- epidermis and dermis, white, cherry red, or black, dry, tissue paper skin, needs grafting, decreased scarring w early excision
Characteristics of 4th degree burn?
muscle, fascia, bone, complete excision required, limited function
Characteristics of electrical burns?
total BSA % difficult to estimate, tissue damage is often more than it looks, renal problems electrical current may cause neuro probs, cardiac damage- arrythmias that persist for months
3 renal complications seen w electrical burns?
myoglobinuria, hemoglobinuria, renal failure
3 ways to manage the renal complications seen with electrical burns?
UO 1-1.5mL/kg/hr, mannitol and lasix, bicarb to alkalinize urine
