fourth degree
what is the term for the substance the occurs on burns following the rupture of vesicles that retreats to the side of the burn?
slough
what is an important consideration following muscle damage from a burn?
there will be an increased level of myoglobin; kidneys will need to expel this so worry about injury
what does partial thickness burns on more than 10% of the body indicate?
transport to a burn center
what does burns that involving the face, hands, feet, genitalia, perineum, and major joints indicate?
transfer to a burn center
what do third degree burns of any type indicate?
transfer to a burn center
a patient with electrical burns should be -
transferred to a burn center
a patient with chemical burns should be -
transferred to a burn center
what are the two ways to estimate the amount of skin affected by burns?
rule of nines, Lund-Browder chart
which way to estimate the amount of surface area affected by a burn is more accurate?
Lund-Browder - considers patient’s age and proportion to relative body area size
in what regions do you have an increased risk for infection following a burn?
nose, ears, buttocks, perineum
what is a priority intervention following a chemical burn?
removing all clothing that contains the chemical (burning process will continue as long as it is in contact with the skin)
what is the first 24 to 28 hour following a burn called?
emergent phase
what is the greatest initial threat following a burn?
hypovolemic shock
edema, decreased blood pressure, and increased pulse are all manifestations of what?
hypovolemic shock
what electrolyte shifts occur during the emergent phase?
potassium leaves the cell and sodium enters the cell
what accumulates at the sight of the burn during the emergent phase?
neutrophils and monocytes
how does a burn effect the immune system in the emergent phase?
bone marrow depression, defects in function of WBCs, inflammatory cascade triggered
this is given to burn patients by going into the intravascular space and taking fluid with it when it is excreted?
albumin
what happens to the hematocrit during the emergent stage of a burn?
it increases
what is a common vascular complication during the emergent phase of a burn?
increased peripheral resistance
what is a common gastrointestinal issue in the emergent phase of a burn?
ileus (inability to stand fluid intake)
individuals who are older, obese, have lower extremity burns/trauma, or have prolonged immobility are at an increased risk for what?
VTE
what can occur if you provide fluid resuscitation too fast?
heart failure

how is CO poisoning treated?
100% oxygen with humidification
what procedure is done by cutting through layers of burnt skin to decrease pressure and increase blood flow?
escharotomy
a patient comes in with burns on more than 15% of their body surface - what is a priority?
placing 2 large bore IVs (fluid therapy)
what fluid are normally given to burn patients?
crystalloids (dextrose, lactated ringers) and colloids (albumin, dextran)
how long should you wait before giving a burn patient colloids? why?

75-100 cc/hr
why is it better to give topical antibiotics rather than systemic?
circulation to burns is poor

rehabilitation
what is a common Musculo-skeletal complication of burns?
contracture
