⩥ Third-degree burns are almost always surrounded by?
What is the appearance? Answer: second-degree burns, which are
surrounded by an area of first-degree burns.
The injury sometimes has an almost target-like appearance because of
the various degrees of burn.
⩥ How is the extent of a burn measured? Answer: Extent is measured by
estimating the amount of total body surface area (TBSA) involved.
⩥ The rule of nines counts Answer: anatomic body parts as multiples of
9% (the head is 9%, each arm 9%, each leg 18%, anterior trunk 18%,
posterior trunk 18%), with the perineum 1%4
⩥ What other factors access the extend of the burn? Answer: Other
factors, such as age, location, other injuries, and preexisting conditions,
must be assessed in order to manage best practice of the burn injury.
,These factors can increase the assessed severity of the burn and the
length of treatment.
⩥ What kind of burns almost always require hospitalization because of
edema? Answer: Genital burns almost always require hospitalization
because edema may cause difficulty urinating and the location
complicates maintenance of a bacteria-free environment.
⩥ People with burns often experience multiple life-threatening
complications such as hemodynamic instability, respiratory failure,
infection, and even multiple-organ dysfunction (MOD Answer:
⩥ ( Hemodynamic Instability)
In a burn victim fluid is lost from?
Because of this what happens? Answer: Fluid is lost from the vascular,
interstitial, and cellular compartments.
Because of a loss of vascular volume, people with major burns often
present in the emergency department in a form of hypovolemic shock
known as burn shock.
⩥ ( Hemodynamic Instability)
,Evidence suggests that lactate serum level at admission can predict,
which people in burn shock are going to benefit from therapeutic plasma
exchange (TPE).
The person has a decrease in cardiac output, increased peripheral
vascular resistance, and impaired perfusion of vital organs. Electrical
injuries that cause burns can produce cardiac arrhythmias that require
immediate attention. Answer:
⩥ Respiratory System Dysfunction Answer: Water-soluble gases, such
as ammonia, sulfur dioxide, and chlorine that are found in smoke from
burning plastics and rubber react with mucous membranes to form
strong acids and alkalis that induce ulceration of the mucous membrane,
bronchospasm, and edema.
Lipid-soluble gases, such as nitrous oxide and hydrogen chloride, are
transported to the lower airways, where they damage lung tissue.
There also may be thermal injury to the respiratory passages.
Manifestations of inhalation injury include hoarseness, drooling, an
inability to handle secretions, hacking cough, and labored and shallow
breathing. Serial blood gases show a fall in the partial pressure of arterial
oxygen (PO2).
, ⩥ What is increased in an effort to balance heat losses from the burned
area? Answer: Heat production
⩥ Hypermetabolism is characterized: Answer: characterized by
increased oxygen consumption, increased glucose use, and protein and
fat wasting, is a characteristic response to burn trauma and infection.
⩥ Burn shock results in impaired perfusion of ? Answer: vital organs.
The person may have impaired function of the kidneys, the
gastrointestinal tract, the nervous system, and musculoskeletal tissues.
Although the initial insult often is one of hypovolemic shock and
impaired organ perfusion, sepsis may contribute to impaired organ
function after the initial resuscitation period.
⩥ Renal insufficiency can occur in people with Answer: burns as a result
of the hypovolemic state, damage to the kidneys at the time of the burn,
or drugs that are administered.
⩥ Immediately after the burn, a person goes into a short period of?
Followed by? Answer: relative anuria, followed by a phase of
hypermetabolism characterized by increased urine output and nitrogen
loss.
