Burns Flashcards
Chemical Burn
-stronng acids and alkalis reacting cause thermal energy
-alkaline more severe than acids
Electrical Burn
-volt contact
-AC burns more severe
Radiation Burn
-depend on dose
Superficial Burns
-1st degree, epidermis
-sunburn
-red, blanches under pressure
-3-5 days
Superficial-Thickness Burns
-superficial 2nd degree, epidermis and papillary dermis
-sunburns, contact burns
-red, moist, blistered skin, edema, painful
-10-14days
Deep Partial Thickness Burns
-deep 2nd, epidermis and derms
-hot liquids, buns
-eschar and blisters
-may be painful or have insensivity
Full Thickness
-3rd, subcute
-immersion scald, flame, steam, chemicals
-mottled white, grey, black
-little pain
Subdermal Burns
-4th degree burn, destruction dermis
-fat, muscle, bone, tendon
-charred
-needs surgical intervention
Rule of Nines
-9% for each area of burn
Lund-Brower Classication
-pediatric scale to account for different head and limb limbs
Palmar Method
-palm sizes to determine burn size
Burn Effect: CV System
-burn shock: perfusion unable to meet demands of body
-need fluids
-BP
-dysrhythmias
-check pulses
Brun Effect: Pulmonary Sys.
-50% need intubation
-pulmonary dysfunction (5-35%)
-carbon monoxide from smoke (50%)
-airway inflammation
Burn Effect: Metabolism
-BMR maybe 2-3x with burns
-elevated body temp and o2 needs
-decrease in body mass
Burn Effect: Immune System
-75% of deaths related to infection
-loss of barrier function
-decreased perfusion for imflammatory response
-bacteria from open skin
