T1 - Integument and Burns (Josh) Flashcards
— burns are the number 1 cause of burn injury to kids under 4.
Scald
What about kids make them more susceptible to scald burn injury?
thinner skin than adults
What is the temp we should keep water heaters?
120 degrees or less
***always test water with BACK of hand
Describe the patho of a burn injury.
Hemodynamics, lead to…
Increasced capillary permeability, leading to…
Plasma leaking into interstitial spaces, leading to…
Fluid loss, leading to…
Increased peripheral vascular tissue resistance, leading to…
Organ hypoperfusion, leading to…
Burn Shock
What happens about 24 hours out from a burn injury?
Capillary membrane integrity is restored, leading to DIURESIS
Patho of Burns:
Within first few hours, we have —- due to leaky capillaries creating edema and increased vascular tissue resistance.
After 24 hours, we have — due to repair of capillaries.
Organ Hypoperfusion
Diuresis
What are the different degrees of burn injuries?
Superficial (1st Degree)
Partial Thickness (Superficial Dermal) (2nd Degree) Partial Thickness (Deep Dermal) (2nd Degree)
Full Thickness (3rd Degree)
Deep Full Thickness
Degrees of Burn Injury:
Which ones have pain?
First and Second Degree
***Third usually doesn’t due to nerve damage
***Deep Full Thickness never has pain
Degrees of Burn Injury:
Describe the appearance of a 1st Degree Burn.
Epidermis
Severe Erythema
Blanches
Red, pink, dry
NO BLISTER
Degrees of Burn Injury:
How long does a 1st Degree Burn last?
Pain for 48-72 hrs
Desquamation in 3-7 days
Heals in 2-7 days
Degrees of Burn Injury:
Describe the appearance of the two types of 2nd Degree burns.
Superficial Dermal
- Large, thick walled BLISTER
- Cherry red, edema
- Mottled red base
- Broken epidermis
- Wet, shiny, weeping
- Blistered
Deep Dermal
- NO BLISTER
- Red, patchy white areas that BLANCH with pressure
- Moderate edema
Degrees of Burn Injury:
Describe the time frame of a 2nd Degree Superficial Dermal burn.
Superficial healing in 7-21 days while deeper healing takes 21-28 days
Mid-dermal healing takes 4-6 wks
MINIMAL SCARRING
Degrees of Burn Injury:
Describe the time frame of a 2nd Degree Deep Dermal burn.
2-6 wks to heal
Spontaneous healing or will require surgical excision and skin grafting
Dermal Necrosis = wound turns from white to yellow
Degrees of Burn Injury:
What is the appearance of a Full Thickness 3rd Degree Burn?
Pale, white, charred
Deep red, black, brown
Dry leathery surface
Severe edema
Fat exposed
Tissue disrupted
No blisters
Degrees of Burn Injury:
What is appearance of a Deep Full Thickness Burn?
Black
NO EDEMA
Degrees of Burn Injury:
Why would a 3rd Degree burn victim pee out blood?
hemolysis of blood leads to blood passed into urine
Degrees of Burn Injury:
Is a 3rd Degree burn capable of self re-epithelialization?
no
skin grafts required
Rule of 9s:
Give percentages to each part that is rated in the Rule of 9s.
Head and Neck = 9 percent
Anterior Trunk = 18 percent
Posterior Trunk = 18 percent
Arms = 9 percent (each arm)
Legs = 18 percent (each leg)
Perineum = 1 percent
Rule of 9s:
What would a burn on upper half of anterior trunk be?
9 percent
***remember full anterior trunk is 18 percent
Do peds patients use Rule of 9s?
No,
they use something like the Lunds-Browder which adjusts surface area for age
Circumferential Burns:
What is the biggest concern with burn that covers the entire circumference of an extremity?
circulation and respiration (if it’s the chest and back)
why? because fluid shifts create problems, especially if skin cannot stretch to account for it
Circumferential Burns:
What do you do with an extremity that has a burn that covers entire circumference?
elevate above heart
check distal pulses q hr
***may also cut into skin to relieve interior pressure
Circumferential Burns:
Why do a lengthwise incision with these types of burns?
Escharotomy-skin cannot expand
Lengthwise incision relieves constriction
NOTES:
- little to no bleeding
- can be done at bedside
- treatment of choice
Signs and Symptoms of an Inhalation Injury
SOB, dyspnea
Hoarsesness
Stridor
Flaring
Tachypnea
Burns to face, neck, mouth
Sooty Sputum
Singed Facial Hair
Swelling of face, neck, trachea
Explain why an Inhalation Injury leads to hypoxemia.
Carbon Monoxide binds to Hg and decreases O2 delivery to tissues
With an inhalation injury, what is protocol to determine O2 level?
ABG and Carboxyhemoglobin level
***pulse ox will not be accurate
What can smoke inhalation lead to?
ARDS
Bronchospasm
Atelectasis
Edema
Infection
***Due to the fact that smoke decreases surfactant production
Carbon Monoxide Poisoning:
What is Normal?
Mild?
Moderate?
Severe?
Fatal?
Normal = less than 2 percent
Mild = 11-20 percent
Moderate = 21-40 percent
Severe = 41-60 percent
Fatal (death) = 61-80 percent
Carbon Monoxide Poisoning:
Signs and Symptoms of Mild (11-20 percent) CO poisoning?
HA
Decreased cerebral function
Decreased visual acuity
Slight breathlessness
Carbon Monoxide Poisoning:
Signs and Symptoms of Moderate (21-40 percent) CO poisoning?
HA
Tinnitus
Nausea
Drowsiness
Vertigo
Confusion
Stupor
Irritability
Hypotension
Pale to reddish purple skin
Carbon Monoxide Poisoning:
Signs and Symptoms of Severe (41-60 percent) CO poisoning?
coma
convulsions
cardiac instability
Treatment for Inhalation Injury
100 percent FiO2 ASAP
EARLY INTUBATION (to prevent swelling from keeping tube out)
Rest
Maintain airway
PEEP
