Burns
Flashcards do conjunto (23)
- 1Whats is a burn?tissue loss caused by an exogenous injurious agent, heat, cold, chemicals, electricity, radiation
severity depends on temp, conc of agent, duration of contact - 2skin functionsprotects against infection
prevent loss of body fluids
control body temp
functions as excretory organ
functions as sensory organ
produces vitamin D - 3General first aid prioritiesstop burning process
remove clothing, unless stuck
cool/irrigate/re-warm
thermal - cool running water for 20 minutes
acid -irrigate -decontaminate 1 hr until burning sensation gone
alkali - irrigate - decominate 2 hr until burning sensation gone
cold induced injury - warm/tepid buckey water
cover the burn and elevate
avoid hypothermia - 4primary surveyairway maintenance with c-spine control
breathing and added oxygen
circulation with haemorrhage control
disability - neurological status
exposure and environmental control
fluid resuscitation - 5airwaymechanism of injury
envirionment injury occured
examine patient for signs of:
burns to mouth, sooty sputum, change in voice, productive cough, stridor, nasal flaring - 6breathingdeep dermal/full thickness burns can affect chest expansion
soot in lower airways
trauma associated injuries - haemothorax, pneumothorax, barotrauma - 7circulationhaemorrhage control
temp, pulse, BP, colour, capillary refill, escharotomy required? to allow expansion
intravenous access - 8disabilitystate of consciousness, AVPU, GCS
- 9Exposure and environmentkeep pt warm, remove all clothing, remove all jewellery, prevent hypothermia, assess burn size, warmed blankets
- 10superficialrapid capillary refill (blanch), thin walled blisters, moist wound (light reflection), pain, heal 7- 10 days
- 11Mid dermalthicker blister
decreasing mosture, decreasing sensation, decreasing cap refill, heal 10-14 days - 12deep dermalcentral white area
dull sensation (no pain)
slow cap refill
slight moistue, heal 2-4 weeks - 13full thicknessno sensation, no cap refill, no moisture, need graft, flap
- 14SHOCKfrom depleted blood volume, low co, vasoconstriction, decrease tissue perfusion, fluid shift continues 36-48 hours
- 15fluid resusitation1st 24 hours - hartmann solution
fluid (mls) = 4mls x %TBSA X WEIGHT (KG)
- give half in first 8 hours
- give half in next 16 hours
monitor urine output - aim 0.5ml/kg/hour
*urine output key to monitoring - 16What increase fluid needs?inhalation injury, dehydration, electrical
- 17probelms of fluid resuscitationoliguria, poluria, fluid overload, haemoglobinuria
- 18aims of burn wound carepromote healing, prevent desiccation of wound, prevent infection, comfort, management, allow movement
- 19management oftemp, hydration, nutrition, infection, oedema
- 20choose a dressinggenerally silver based due of risk of infection
transporting patients
products - 21initial wound caregive appropriate pain relief
debride all blistered non-vial skin
shave wound to decrease bacterial load
shave 5-10cm margin around wound
aid future wound cleansing - 22Scar managementrequires skin grafting
un-grafted area that take longer than 10-14 days to heal on assessment
involves massage and moisturisation, pressure garments
generally 2-3 times daily, water-based moisturiser, firm pressure
benefits - softens scar, increase pliability, reduces, cracking,decrease itch and risk of infective breakdown - 23—
