Burns Flashcards
(38 cards)
What are the four types of burns
Thermal Burns
Flash, flame, contact, scalding burns
Can include radiation buns
Chemical Burns
Acids, alkalis, organic compounds
Electrical Burns
Intense heat generated by electrical current
Inhalation Injury
Chemicals, hot air, or other substances can damage the airway
What is the difference between partial and full thickness burns?
Partial thickness (anything above subcutaneous tissue)
1st degree involves epidermis
2nd degree involves epidermis and dermis
Full thickness (subcutaneous tissue down to bone)
3rd degree involves epidermis and dermis down to subcutaneous fat, muscle and possibly bone
Using the rule of nines, what parts of the body are considered 4.5%
front/back of head
front/back of entire arms
Using the rule of nines, what parts of the body are considered 9%
front/back of chest (upper back)
front/back of abdomen (lower back)
front/back of legs
Using the rule of nines, what part of the body is considered 1%
genitals
What is the Emergent phase:
first 72 hours after the burn has occurred
What is the Acute phase:
Starts after 72 hours and ends when partial-thickness wounds are healed or full thickness are grafted-lasts weeks to months
What is the Rehabilitation phase:
wounds have nearly healed and they are able to participate in self-care
What are the two major parts of injury in the emergent phase of a burn
Burn injury causes damage to tissue, then inflammatory response (increased capillary permeability) causes more issues such as:
fluid out of the intravascular space and into the interstitial spaces (third spacing)
Shift of electrolytes and possible necrosis of tissue
The immune system is also compromised because the skin is removed and the inflammatory process reduces the availability of the innate and specific immune systems
At risk of hypovolemic shock
Expected labs for burn victims
Hypoalbuminemia
Hyponatremic
Hyperkalemic
Increased BUN, creatinine
Low GFR
ABGs (effects of respiratory injury)
Manifestations of the emergent phase of a burn
altered mental status possible
high level of pain for superficial burns no pain for deep burns
tachycardia, hypotension, dysrhythmias
hoarseness, difficulty swallowing, hypoactive/absent bowel sounds
oliguria
Manifestations of a First degree Thermal Burn
-blanching with pressure, tenderness, pain, redness
Manifestations of a Second degree Thermal Burn
-blanching with pressure, pain, blisters, change in skin color
Manifestations of a Third degree Thermal Burn
-absence of pain, eschar, impaired sensation, no blanching
Manifestations of a First degree Electrical Burn
Cardiovascular disruptions-dysrhythmias, cardiac arrest
Manifestations of a Second degree Electrical Burn
May look superficial, but will have internal injuries that are more severe
Manifestations of a Third degree Electrical Burn
Possible fractures or dislocations from muscle contraction
What is the first intervention for a chemical burn
remove the source of the the chemical burn
What are the secondary effects of major burns you should monitor for?
acute kidney injury
What is a TBSA calculation
Total Body Surface Area (Rule of Nines)
What are some medications you treat for the secondary effects of major burns
Analgesics
Sedatives
VTE prophylaxis
Tetanus immunization
Antibiotics/antimicrobials
Fluid therapy (use Parkland Formula)
Isotonic fluids-most commonly LR
Possible albumin administration
What is the Parkland Formula
Determine fluid resuscitation for burn victims over the first 24 hours by:
multiplying 4ml times the percentage of body surface area times the patient’s weight in kg
multiply by .5 and give first half the first 8 hours and the second half the next 16 hours
If pt produces less than 30ml of urine/hr with current level of fluid therapy, tell doc. SHOULD have large diuresis as fluid shifts back into interstitial space
Circumferential burns (compartment syndrome) often require what intervention?
Escharotomy or fasciotomy (allows swelling to occur without compromising circulation)
What are the two types of wound care?
Open method: creams and salves with no dressing (around face and head)
Closed method: Burns have dressings
