Burns injury Flashcards
Define burns injury
Caused by excessive temperature and fire, chemicals , electrical current
Assessed by the size (% of the body covered) and the thickness (first to 4th degree-full thickness(
Aetiology and risk factors (TYPES) of burns injury
Can be thermal, electrical, chemical
Care-often non-accident (20% are abuse)
Local response-coagulation of tissues and microvascular changes-swelling
Systemic-when 20% of the body is covered-fluid loss and vasodilation (capillary leak, oedema, organ dysfunction
will self limit in well resuscitated patients
big risk for secondary infection
First degree-like severe sunburn
Second-Scalding injury
third degree-flame or contact
4rth-high voltage injury
risk factors-male, young
Epidemology of burns injury
UK
250000 per year
175000 attend ED
only 12000 are admitted
4th degree are quite rare in the end
180000 in the world die from it-mainly in developing countries
Signs and symptoms of burns injury
First degree-Red, painful to touch, dry
Second degree-Wet, painful to touch, red, swollen
Third degree-epidermis and dermis-white/mottled, not painful
4th degree-tendon, muscle and bone involved-dark black, insinuate
commonly expect smoke inhalation-hoarse voice, harsh cough, stridor
And secondary staph aureus cellulite
Investigations of burns injuries
The main issue is to assess the burn-degree and % of body covered
usually se burns calculator for fluids given
FBC-hypovalemia, thrombocytopenia
Carboxyheamoglobin-high in smoke inhalation
wound biopsy culture/histology-sepsis
Management of burns injury
Any major burns (25% of body, partial thickness)-send to ressuss
ask specialists
Airway-bronchospcoy can help with smoke inhalation. or intubation
breathing-burns can impair thorax, and cause pneumothorax
give 100% o2
Circulation-IV fluid -2 large bore cannulas-crucial lifelines
reassess-4x weight x % coverage of body=ml of hartmans/24h
Cool the burn, warm the patient
(don’t cool patient-intensify shock)
Decompress if compartment syndrome
dont burst blisters
Parafin gauze
Iv morphine
Abx prophylaxis
dressings
