21 Cards in this Set

  • Front
  • Back
1st and 2nd line of defense
1st --> skin (an organ)
2nd --> immune system
skin functions
- protection
- temperature regulation
- vitamin d synthesis
- pain sensation
- pressure
most common burn injury
thermal
least common burn injury
radiation
four mechanisms
1. thermal
2. chemical
3. electrical
4. radiation
thermal
caused by a heat source

- thermal burn occurs when skin is directly damaged by temp.
thermal classified into 3 zones
* zone of coagulation
* zone of stasis
* zone of hyperemia
thermal: zone of coagulation
damaged skin and underlying tissue that represent cellular death
thermal: zone of stasis (surrounding the zone of coag.)
living tissue around which increase blood flow occurs
thermal: zone of hyperemia
where living tissue shows sign of the inflammatory response
chemical
contact with an acid, alkali, or organic compound

- often are absorbed systemically

- can be used as assault weapons
what does the severity of a chemical burn depend on?
- type of agent
- concentration
- volume
- duration of exposure
nursing care for the chemical burn pt.
* prevent the spread of the chemical injury

rationale: to prevent further injury

* protect all people who come in contact with the injured person
electrical
can occur secondary to high or low -voltage e-

- cause minimum cutaneous injury but are assoc. with vague c/o pain and neurological signs and symptoms
electrical
high voltage usually causes deep underlying injuries & visible tissue damage
radiation
severity of theses burns can range from minor to lethal
radiation: exposure may result from
- air transmission
- inhalation
- ingestion
- skin contact
classification of burns
by size and depth
burns
only partial and full thickness burns are calculated
another rule of thumb for calculating
is the palm of the hand, which can serve as a measure

- the entire palm surface is approx. 1% of TBSA (total body surface area)
rule of nines
most universal accepted tool and must be modified for peds patients
