Question: Superficial burn
Answer: epidermis only
Red, dry, painful, blanches, no blisters
Heals without grafting
Question: Partial thickness burn
Answer: epidermis+part of dermis
pink, red, moist, blisters, very painful, blanches
Question: Full thickness burn
Answer: entire epidermis+ dermis destroyed
white, brown, black, dry, leathery, little to no pain in center because nerves are destroyed
usually requires grafting
Question: which burn is usually the most painful
Answer: Partial thickness, because nerve endings are exposed
Question: why can a full thickness burn be painless
Answer: nerve endings have been destroyed
Question: wheeze
Answer: muscle sound usually caused by lower airway narrowing/bronchospasm
Question: Stridor
Answer: High pitched sound caused by upper airway obstruction
Question: Thermoregulation
Answer: burned skin cannot regulate temperature effectively, high risk for hypothermia. Keep
environment warm
Question: Rule of 9's
Answer: -adult head+neck 9%
-Each arm 9%
-anterior trunk 18%
-posterior trunk 18%
-each leg 18%
-perineum/genitals 1%
Question: Baux score
Answer: age+ % TBSA burned
example
age 60+30%TBSA=90
, Question: Eschar
Answer: thick, dry, leathery dead tissue covering a full thickness burn
Question: dermatome
Answer: surgical instrument used to remove thin layers of skin for a skin graft
Question: Escharotomy
Answer: incision through eschar to relieve pressure and restore circulation/ventilation
Question: Fasciotomy
Answer: incision through fascia to relieve severe compartment pressure
Question: debridement
Answer: removal of dead/devitalized tissue to promote healing and reduce infection risk
Question: when does emergent phase occur?
Answer: from time of injury until fluid resuscitation is established and capillary leak begins
resolving usually about first 24-48 hours
Question: Biggest problem during emergent phase
Answer: Hypovolemia/hypovolemic shock
Question: why does hypovolemia occur
Answer: increased capillary permeability causes fluid to shift from blood vessels to interstitial
tissues
Question: Emergent phase vitals
Answer: low BP
high HR
high RR
Question: Emergent phase urine output
Answer: decreased due to reduced renal perfusion
Question: emergent phase hematocrit
Answer: increased
Question: emergent phase potassium
Answer: HYPERkalemia
Question: emergent phase sodium
Answer: HYPOnatremia
