Burns pt.2🔥 Flashcards
Massive cell destruction can result in ___________ immediately after a burn. ____________ can occur later in the acute phase with fluid shifts and inadequate K+ replacement
hyperkalemia; hypokalemia
surgical debridement done in a timely manner has many benefits to burn patients. Why is it one of the most important factors that contributes to survival after a burn?
-reduces complications related to infection
-shorter hospital stay
Why is the hematocrit elevated in the emergent phase of a burn?
due to plasma loss - this higher concentration of blood cells is happening because fluid is shifting out of the bloodstream and into the interstitial spaces
hyponatremia is also occurring due to this same fluid shift
How many sones are there in a burn?
3
The zone of coagulation, is the innermost zone, this is where cellular death occurs. does this zone sustain the most or least damage?
the most
The zone of stasis, is the middle zone. What are the characteristics of this zone?
-tissue injury
-compromised blood supply
-inflammation
The zone of hyperemia is the outermost zone, this zone sustains the ______ amount of damage.
least
_____ degree burns are associated with scalds and flash flames.
2nd
____ degree burns are associated with sunburns.
1st
_____ degree burns are associated with direct flame, electric currents or chemical contact.
3rd
An ________ is a biologic source of skin similar to the patients, like from a cadaver.
homograft
A _________ is obtained from pigs skin, sometimes cows.
xenograft
An ______ is when the skin graft comes directly from the patients own skin.
autograft
How would you describe the appearance of a full thickness burn?
pale white
leathery
dry
charred
How much protein does a burned patient need to meet nutritional needs?
1.5 -2g/kg/ day
How soon is the dressing changed after an autograft surgery is performed?
2-5 days post op
Snug fitting dressings or garments are worn 23 hours a day to apply continuous pressure. This can __________ burn scars and help to smooth the skin.
minimize
About how long will it take for a deep partial thickness burn to heal?
2-4 weeks
Why should elastic bandages be wrapped distally to proximally on dependent areas?
(from extremities, inward to the center of the body)
-limits edema
-decreases bleeding
-promotes graft acceptance
(pushes fluid back to the heart to prevent accumulation)
Burns should be wrapped ________ to _______ because it promotes venous return and prevents edema.
proximal to distal
(from the center of the body, out to the extremities)
After a serious burn, what is the most serious complication related to the GI system?
paralytic ileus
What is Biobrane?
a nylon silicone membrane that is coated with protein
What is Mederma?
a topical gel used to reduce scarring
What is Integra?
a 2 layered membrane; 1 layer is a synthetic epidermis and the other later is made of collagen fibers to mimic the dermis
