Week 8 - Burns Flashcards
why is skin integrity important
- first line of defense for the body
- acts as a barrier from the external elements, bacteria, and viruses
= impairement of skin integrity = body vulnerable to hosts of potential complications & infection
what are some functions of the skin (3)
- thermoregulates
- helps regulate fluid & electrolyte balance
- communicates w brain thru nerves to identify sensory factors like pain & temp
what are 5 types of burns
- thermal
- chemical
- electrical
- smoke & inhalation
- cold thermal
what are thermal burns
- burns caused by flame, flash fire, scalding, or contact w hot objects
- most common type of burn injury*
what are chemical burns
- burns result from tissue injury & destruction from acids, alkali, and organic compounds
chemical burns can effect.. (2)
- the skin
- eyes
what are some examples of causes of chemical burns (4)
- household cleaners
- phenols
- heavy infustrial cleaners
- fertilizers
are alkali or acid burns more difficult to manage? why?
- alkali
- they are not neutralized by tissue fluids as readily as are acid substanced
what are smoke & inhalation burns/injuries
- damage to tissue of the resp tract (usually resp mucosa) d/t inhalation of hot air or noxious chemicals
smoke & inhalation injury leads to (2)
- redness
- airway swelling
= major predictor of mortality in burn injured patients
what is imp regarding smoke & inhalation injury
- rapid assessment (d/t major predictor of mortality)
what are electrical burns
- result of intense heat generated from an electric current
all pts with electrical burns should be considered at risk for ..
- potential cervical spine injury (contact w electrical current can cause muscle contractions strong enough to cause fractures of long bone & vertebrae)
electrical burns put the pt at risk of (5)
- dysrhytmias
- cardiac arrest
- severe metabolic acidosis
- myoglobinuria –> ATN
- vfib
what are examples of causes of electrical burns (3)
- powerlines
- lightning
- faulty electrical in houses
what is an example of a cold thermal injury
- frostbite
treatment of burns is related to
- severity of injury
severity of injury d/t burns is related to (4)
- depth of burn
- extent of burn calculated in percentage of total body surface area
- location of burn
- pt risk factors
what is a superficial burn
- 1st degree
- burn that causes damage to the epidermis
describe the clinical appearance of a superficial burn (7)
- erythema
- blanching w pressure
- pain
- no or mild swelling
- no vesicles or blisters
- dry
- hot
describe the impact of a superficial burn on tactile and pain sensation
- still intact
what are 2 examples of causes of superficial burns
- superficial sun burn
- quick heat flash
what is a deep partial thickness burn
- 2nd degree
- involves the epidermis and dermis to varying depths
describe the clinical appearance of a partial thickness burn (6)
- shiny
- wet
- fluid-filled vesicles
- severe pain
- mild to mod edema
- shades of pink, red, white
