- What is the pathophysiology of a Burn?
- tissue destruction can cause many local and systemic problems including fluid and protein losses, sepsis, and disturbance of the metabolic, endocrine, respiratory, cardiac, hematologic and immune systems.
- What are the 5 types of burns?
Partial-thickness * superficial and deep
Full thickness (escar develops)
- Describe a superficial burn
- pink to red color, mild edema, no blisters. EX: sunburn, flash burn
- Describe Partial-thickness superficial
- *Pink to red skin, moist
*Mild to moderate edema
* intense Pain
*approx 2 wks to heal
EX: scalds, flames
- Describe Partial-thickness deep burn
- *deeper into the dermis
*red to white skin,waxy without vesicles
* blood supply < = vasoconstriction
* may progress to deeper involvement
*2-6 wk healing
*grafts might be used
*EX: scalds, flames, tar, grease, chemicals
- Describe Full-thickness burns
- * enditre epidermal and dermal layers involved.
*black, brown, yellow, white or ered skin
*No epidermal tissue
* servere edema
*eschar Must be removed for healing
*weeks to months to heal
Skin grafts required (>12-16)
Escharotomy/or Fasciotomy may be necessary
- Descrobe Deep Full thickness burns
- Extend into fasica/tissues/bones
Weeks to months to heal
EX: flames, electricity, grease , tar, chemicals
- why are there vascular changes resulting from burns?
- Damaged macrophages within the tissue realease chemicals that intially preoduce vasoconstriction. Following vasoconstriction the vesels dilate.Which causes increased capillary premeability.
- What is third spacing?
- leaking of plasma from the intravascular space into the interstitial space. Resulting in a decreased colloidal osmotic pressure in the vascular space. This caused edema.
- As a result of 3rd spacing what can you see imbalances of?
- F & E ,
- The Inflammatory response gradually subsides within ...
- 24-36 hrs. the fluids shift back into the circulation. thus called Remobilization
- What phase will you usually see hyponatremia, anemia, and hypoKalemia?
- Fluid Remobilization. as inflammatory responses decrease. Na lost through wounds, K returns to intracellular compartment, anemia as a reult of hemodilution.
- Pulmonary changes are a major couse of morbidity T or F?
- What is a Curlings ulcer and where is it
- GI ulcer may develp within 24 hr after a severe burn injury.
- What drugs are used to decrease chances of developing Curlings ulcer?
- Taament, Zantac or Carafate
- What are some metabolic changes you will see with burns?
- hypermetabolic state requiring > calories and protein up to 5000. these req peak 4-12 days after burn and can last months
* > body core tem, low-grade T
* > oxygen requirements
- The Sympathetic nervous system response is a compensatory response describe this.
- evident in cardiovasuclar, respiratory and GI system.
- when is the emergent phase and what do you assess?
- 1st hr
limit extent of injury
