Term
explain the epidermis after a burn injury
Definition
it can grow back fairly quick because the cells surrounding the sweat and oil glands and hair follicles extend into the dermis -
Term
where do the nutrients come from to heal the epidermis after a burn
Definition
from the bottom layers becuse there is no blood vessles
Term
what happens in the dermis after a burn injury is just minimal what if its sever?
Definition
skin can regrow as long as parts of the skin are still present, when the entire dermis is burned all the epitehlial cels and dermal appendages are destroyed and the skin cant restore itself
Term
all bruns are painful!! what is exposed with partial thickness burns
Definition
nerve endings that increase sensitivity and pain
Term
what is exposed with full thickness burns and what type of pain is felt
Definition
nerve endings are destroyed the pt have dull pressure but the wound edges still may have sensory intact and can cause pain
Term
what happens with vitamin d and partial thickness burns and what about full thickness burns
Definition
reduces the activation of D and in full thickness burns this is completely lost
Term
what temp can the skin tolerate temps up to without injury/ and what happen abve this temp
Definition
158*/ above this temp cell destruciton is so fast that even breif exposure the skin below is damged
Term
what color would a cuperficial and partial thickness burn be
Definition
pink to red
Term
what color is a deep partial thickness burn
Definition
red to white
Term
what color is a full thickness burn
Definition
black brown yellow red or white
Term
explain the pain in a superficial burn
partial thickness
deep partial
full thickness
Definition
pain in all of the first 3 and then in full thickness it can be ther is deep full thickness the pain is absent
Term
what is a minor burn
Definition
deep partial thickness less then 15%
Term
what is a moderate burn
Definition
deep partial thickness 15 to 25%
Term
what is the criteria in a pt with a minor or moderate burn in order to be in this cateogry with their health
Definition
must be younger then 60 no heart, lung or endocrine disorders
Term
what can not be burned in order to classify under minor or moderate burns
Definition
no burns of the eyes ears face hands feet or perineum
Term
what is body part included in a major burn
Definition
eyes
ears
feet
hands
perineum
Term
desquamination
Definition
peeling of dead skin
Term
what are superficial partail thickness wounds caused by
Definition
injury to the upper third dermis leaving a good blood supply
Term
the superficial partial thickness wounds are red and moist do they blanch with pressure
Definition
yes
Term
the small vessles in the superficial partial thickness burn are damage so what happens
Definition
theyleak plasma and lifes off the ehat destroyed epidermis causing blisters
Term
small blisters from a bunr may be left intact what do they do with larger blister
Definition
open and debride then to promote healing
Term
deep partial thickness wounds extend into the dermis and fewer healthier cells remain why dont blisters form here
Definition
because the dead tissue layer is thick and sticks to the underlying dermis so it cant really lift off the surface
Term
full thickness wounds is from destruciton of the entire epidermis and dermis what does this wound require and why
Definition
grafting because it can not regrow
Term
what is apparent on the full thickness burn and what is done with it
Definition
eschar and this must be removed before healing can occur
Term
why is eschar removal from a full thickness burn difficult
Definition
because it sticks to the lower tissues with collagen
Term
escharotomies/ fasciotomies
Definition
incisions thru the eschar/ incisions in the eschar and into the fasica
Term
deep full thickness burns extend beyound the skin into dep underlying fascia and tissues what else is damaged in these burns
Definition
muscles
bone
tendons
Term
circulating disruption happens immediately after a burn what happens to the blood vessels
Definition
they are occluded and blood flow is reduced or stopped
Term
what happens after vascoconstriction initially after a burn
Definition
the fluid shifts into the interstitial space and its a continuous leak of plasma
Term
what does the amount of fluid shifted in a burn depend on
Definition
the amount of burn and extent
Term
where does capillary leak occur after a burn
Definition
both burned and unburned tissues
Term
why does edema develop from a burn
Definition
because the proteins are now in the interstitial spave and causes movement of fluids out from vascualr space
Term
what are four imbalances that occur from a burn
Definition
hypovolemia
hyperkalemia
acidosis
hyponatremia
Term
why does hyperkalemia occur after a burn
Definition
cells injured release large amounts of potassium
Term
why is sodium retained after a burn
Definition
stress- aldosterone secreation increases leading to increased sodium reabsorption
Term
hemoconcentration develops from a burn why
Definition
from vascular dehydration
Term
fluid remopbilization
Definition
happens 24 hours after burn when the capillaries stop leaking
Term
what happens during the diuretic stage of a burn
Definition
low sodium low potassium anemia
Term
whjen would a person need a transfusion after a burn
Definition
if the hematocrit is less then 25% with hypoxia
Term
what are the heart changes after a burn
Definition
increased hr
low output
Term
what happens with burn to irrantant that enter the lungs
Definition
a reflex occurs whent he vocal cords close off to educe the entry of smok
Term
what can leaking capillaries do to the pulmonary system
Definition
alveolar edema
Term
what happens to the gi system with a burn
Definition
gastric motility is decreased and the secreations and gases collect in the intestines and stomach
Term
curlings ulcer
Definition
acute ulce that occurs with the stress of a sever injury
Term
what is used toprotect the gi after a burn injury
Definition
h2 histamine blockers nd proton pump inhibitors
Term
serious burn injuries can increase metabolism how does it do this
Definition
increases catecholamines
antidiuretics
aldosterones
corisol
Term
the hypermetabolic state increases the body temp why does the core temp increase
Definition
because the person has lost the eat thru burned areas and teh hypothalamus this is trying to reset the bodys normal temp to a hgiher baseline
Term
dry heat injuries
Definition
caused from an open flame
Term
moist injuries
Definition
scald injuries
Term
contact burns
Definition
from hot metal grease contact thes skin
Term
chemical burns
Definition
chemical on the skin or ingested
Term
alkalis where is this chemical found
Definition
oven cleaners fertilizers drain cleaners
Term
what do alkalis chemical do to the skin
Definition
causes the skin proteins to liquify
Term
alkalis liquifies proteins in the skin what does this allow for burns
Definition
deeper spread of the chemical and more sever burns
Term
grand masquerder of burns
Definition
electrical burns because they lok small but internal damages can be horrible
Term
bone will allow electrical flow along the surface why
Definition
because is has a high resistance because its density

transported across lung membrae and is bond to hemaglobin in place of o2 causes the curve to switch to the left

Definition
edema obstruction epiglottis
Term
circulatory overload may cause
Definition
chf
Term
during a fluid shift with a burn what happens to the kidneys
Definition
urine is decreased and urine is concentrated as a high specific gravity
Term
when muscle damge has occured from a burn what happens
Definition
myoglobin is released and circulates to the kidney all of the molecules can create a sludge in the kidney and block flow
Term
what is fluid recusitationprovided at to maintain urine output
Definition
30 to 50 ml
Term

Term
use the rule of nine of the lower half of the body
Definition
rt let anterior9% posterior 9%
lt leg anterior 9% posterior 9%

Definition
4.5% anterior and posterior
Term
explain the persons wbc count immediately after a burn and then later in the stage
Definition
early the wbc rise then drop dramatically with a left shift
