burns Flashcards
what are the layers of the skin
epidermis, dermis, subcutaneous
partial thickness burn
pink to red, moist, mod deem, painful
top layer and dermis aka 2nd degree
superficial burn
first degree. erythema, mild edema/pain. blanches of pressure
full thickness brun
third degree epi and dermis destroyed. white waxy to black. dry, deem, painless.
fourth degree burn
dry, black painless, could have exposed mm / bone
which burn associated with inhalation injury
flame
whats high n low voltage injuries
> 1000 or less V
how are most adult burns
fire flame and then scald and then contact
how are most kids burns
scalds, contact, flame electric
risk of mortality goes up with
age, size and if there was inhalation
what are the zones and whats the worst area
coagulation, stasis, hyperaemia (coag. is irreversible)
target stasis cus it can go either way
cardiac effects of burns
inc cap permeability (edema, hypovolemia).
peripheral vasoconstriction
dec CO
renal effects of bruns
loss of fluids
metabolic effects burns
goes up because increased nutritional demands
immunological/ gastro effect burn
reduced response / compromised
signs of inhalation injury
singed eye brow / nasal hair
swollen lips, hoarse voice, face burn
when does inhalation injury happen
0-24 hrs , in upper airway
24-48 hrs pulmonary edema
38 = ARDS, pneumonia , bronchiolitis
early burn PT role
AROM, PROM, poisoning, edema management (elevate, compress), ambulation , scars
what motion does you lose first
tissue, tendon, mm (2-3 weeks), ligaments
contraindications for PT
exposed joint, DVT, compartment syndrome, new skin graft
whats the progressive dependency protocol
observe, figure 8 wrap , place limb in dangle (DEPENDENT position ) , elevate, remove wrap and re assess
how often do silver acticoat need to be changed
5-7 days
how long are split thickness skin grafts immobilized
5 days
advantages for full thicken skin graft
decreased secondary contracture, and durability,
scar is soft in what stages
stage 1 and 3
pressure garments management
replace every 2-3 months
