Burns
Cards in this deck (10)
- 1Burn injury zones3 zones of a burn injury:
zone of coagulation
zone of stasis
zone of hyperemia - 2Zone of coagulationexposed to most heat, ensues most damage
- 3Zone of stasissurrounds the zone of coagulation. Damage here results in decreased tissue perfusion; tissue may be salvageable.
The main goal of burn resuscitation is to increase tissue perfusion here and prevent irreversible damage. - 4Zone of hyperemiadamaged but should recover and heal with proper care
- 5What is the Rule of 9s?A quick method used to estimate extent of burn. Each arm is 9% of body, head & neck is 9% trunk anterior or posterior 9%; each leg is 18%; genitalia 1%
- 6Describe the different burn depths 1-4th degree1st degree (superficial) - only epidermal layer; no blisters i.e. sunburn
2nd degree (superificial partial thickness) - destroys epidermis and extends into dermis
3rd degree - full thickness - destroys entire epidermis, dermis, and reaches subcutaneous fat
4th degree - deep full thickness - destroys all skin layers and reaches skeletal system - 7Burn healing expectations by level?Superficial - 3-4 days
superficial partial thickness - 2 weeks
full thickness - depends on donor availability
deep partial thickness - 3+ weeks - 8Other injuries related to burns* inhalation injury
* burn shock
* hypermetabolism
* infections
* scars
* contractures - 9Inhalation injuryincludes thermal injury, carbon monoxide toxicity, asphyxia, cyanide toxicity
- 10Burn shockoccurs with 48-72 hours post-injury. This happens when more than 20% TBA and the presence of burn wound edema. The first 12 hours is the most significant time.
