The flashcards below were created by user alyn217 on FreezingBlue Flashcards. What would you like to do?


  1. What is important about the stratum Germinativum?
    This is where most cells regenerate. Whether or not a burn is deeper than the SG often determines if it will heal on its own.
  2. What is a partial thickness burn?
    • destroys epidermis
    • appears red, swollen and blistered
    • usually heals in 2 weeks
    • can extend into the dermis (deep partial thickness burn)
    • Will heal well functionally and cosmetically.
    • Will blanch to touch.

    • Deep partial:
    • Very painful
    • may appear mottled with pink or red to waxy white areas with blisters and edema
  3. Full thickness burn?
    • Dry, leathery, penetrates all layers of skin.
    • Usually painless except around the margins. 
    • Sensory input also gone. 
    • Will not blanch to touch.
  4. What do you need to remember about assessing emergent skin burns?
    • ABCs FIRST!!!
    • Then...
    • Disability
    • Exposure
  5. What to do with a burn pt.
    • Intubate at 100% O2, but...
    • ...get info first if possible. 
  6. What/when are you thinking with inhalation injury?
    • enclosed space?
    • fumes?
    • smoke?
    • stridor
    • carbonaceous sputum?
    • singeing around face/mouth/nose?
    • change in voice from baseline?-->think damage at larynx or below. 
  7. How can a full thickness burn around the trunk affect breathing?
    • Can impair ventilation
    • Respiration should be closely monitored.
  8. T/F a little bleeding is normal with burns.
    • False
    • If you find bleeding, find the source and stop it. 
    • If need fluid, us LR.
  9. How is prehospital fluid management calculated?
    • <6yrs---125ml/hr
    • 6-13yrs---250ml/hr
    • >13yrs---500ml/hr

    After hospital admission, they get a foley and fluids are very tightly controlled. 
  10. T/F Your burn pt should be alert.
    • True
    • If not, find out why, ie
    • --CO poisoning
    • --substance abuse
    • --hypoxia
    • --pre-existing conditions like seizure
    • AVPU: Alert Verbal Pain Unresponsive
    • Identify any gross deformity/serious associated injury. 
  11. Exposure/Environmental control phase
    • remove clothing, jewelry, metal, diapers, shoes, etc.
    • Log roll pt to remove clothing. Assume spinal cord injury
    • Keep warm by covering with dry sheets. 
  12. What happens during the secondary survey?
    • Hx? Especially tetanus?
    • wt?
    • head to toe exam
    • %TBSA?
    • Admin lines/tubes
    • Fine tune fluids/cath.
    • extremity perfusion
    • ventilation?
    • pain?
    • Psych assessment
    • Reassess ABCs
  13. How do you calculate TBSA?
    • Rule of 9s
  14. Bullet points about burn traumas
    • spinal until r/o
    • dont get distracted by the burn. Remember ABCs first.
    • Burns alone don't cause unconciousness or hypotension.
  15. What is an escharotomy/fasciotomy?
    • Escharotomy: cutting through burned tissue to relieve pressure. Does not usually require OR.
    • Fasciotomy: removal of dead tissue to prepare for graft. Muscle layer is exposed. 
  16. Initial wound care?
    • Cover
    • Transport
    • Report using SAMPLE method.
  17. Fluid calcs for adults after hospital admit
    • Adult >14yrs. 
    • 2ml LR x TBSA x kg
    • Give half over 1st 8hrs, other half over next 16. 
    • Adjust to UO to 30-50ml/hr. 
    • If urine out of target for 2 consecutive hours increase or decrease fluid by 1/3. 
  18. Fluid calcs for peds after hospital admit
    • 3ml x kg x TBSA
    • same admin regimen as adults.
  19. Med calcs for electrical injuries
    • 4ml Lr x kg x TBSA
    • UO--> 75-100ml/hr
    • May need to increase uo to 1-1.5ml per kg to maintian clear urine. 
  20. Chemical burns?
    • protect yourself
    • brush off if possible, remove clothing, irrigate for at least 20 min. 
    • identify agent if at all possible. 
    • chemical burn alone-->burn unit
  21. Electrical burns?
    • Bone has high resistance so flows along bone surface and damages adjacent muscles
    • small surface burns can indicate deeper, more extensive damage. 
    • Can have "entrance" and "exit" points where current travels. 
    • Requires debridement internally.
