Burn Notes Flashcards
Superficial partial-thickness burn signs & symptoms
erythema (redness) blanching on pressure (whitens with applied pressure) pain mild swelling can blister and peel after 24 hours
Superficial partial-thickness burn involved structures
epidermis
Epithelization (Skin growth) can occur
Deep partial-thickness burn signs & symptoms
blisters
severe pain due to nerve damage or death
mild to moderate edema
Deep partial-thickness burn involved structure
Epidermis and dermis
Full-thickness burn signs & symptoms
Leathery skin that can be dry or waxy You can see burst vessels Visible tendons, fat, muscles and bones No pain due to nerve death Possible skin necrosis
Full-thickness burn involved structures
Destroyed skin & local nerves
Who are the high risk factors of burns?
Children younger than 4 and adults over 65.
What are the types of burn injuries?
Thermal - most common Chemical Electrical Smoke inhalation - most deadly Cold Thermal
How do you determine the severity of burns?
Rule of Nines - initial assessment
Lund-Browder chart - more accurate
Rule of Nine: Give the parts and their percentage
Head - 9%, 4.5 each for front and back Trunk (includes chest, back, and butt) - 36%, 18 each for front and back Arm - 9%, 4.5 each for front and back Perineal - 1% Leg - 18%, 9 each for front and back
Lund-Browder: Give the parts and percentage
Face- 3.5 Back of head - 3.5 Front Neck - 1 Back of Neck - 1 Chest- 13 Back- 13 Shoulder & Upper Arm- 2 Lower Arm- 1.5 Wrist and Palm- 1.5 Perineal- 1 Butt- 2.5 each buttcheek Upper leg- 4.75 Lower leg- 3.5 Ankle and feet - 1.75
How do you prevent hypothermia for large burns?
Do not cool for more than 10 min.
Do not soak
Do not cover with ice
How do you care for a patient with burns for prehospitalization?
Ensure ABCs
Provide 100% Humidified O2
Remove clothing gently
Wash chemical burns with water for 20 min to 2 hours
Wrap burned area with clean sheet or dry blanket to prevent infection
Tissue destruction can occur for how many hours after burn exposure?
72 hours
What are the phases of burn management?
Emergent
Acute (Wound Healing)
Rehabilitative
What are the main concerns in emergent phase?
Hypovolemic shock and edema formation
Fluid & Electrolyte shifts in Emergent phase
Water, Electrolyte and proteins move into interstitial spaces due to increased capillary permeability.
Protein pressure within blood stream (Colloidal osmotic pressure) decreases.
Third spacing occurs
RBCs are depleted but high Hct is shown due to hemoconcentration
Potassium shifts first, then sodium
Hypovolemic shock signs & symptoms
Decreased BP and increased HR
What signifies the end of emergent phase?
Diuresis and urine has low specific gravity
C/M of Emergent phase
Evidence of partial or full thickness burns (pain, blister formation, etc.)
Paralytic ileus (absent bowel sounds)
Shivering
Unconsciousness or altered mental status due to hypoxia
What three major organ systems are susceptible for complications during the Emergent phase?
Cardiovascular
Respiratory
Renal
Cardiovascular complications in Emergent phase
Dysrhythmias
Hypovolemic shock
Impaired circulation - sludging (poor circulation in capillaries)
Venous thromboembolism (VTE)
Respiratory complications in Emergent phase
Pneumonia (PNA) - leading cause of death Upper Airway injury Lower Airway injury Metabolic Aphyxiation Respiratory distress Pulmonary Edema Sputum has carbon
Signs & Symptoms of Respiratory Distress
Increased agitation
Restlessness
Abnormal breathing patterns: tachypnea or bradypnea
