Burns
parkland formula
4mL LR x TBSA % burned x patient weight (kg) = total amount of fluid this is just an estimation and may change depending on patient UO and hemodynamic status
primary assessment
ABCDE
rule of nines
a system that assigns percentages to sections of the body, allowing calculation of the amount of skin surface involved in the burn area
lower airway injuries
airflow obstruction due to chemicals can cause respiratory failure, ARDS, and pulmonary infections
psychosocial
appearance functional status healing process
2nd degree superficial partial thickness characteristics
blisters erythemic weeping of serous fluid painful
electrical burns can result in decreased
neuro status may be delayed onset
disability
neuro status, LOC
upper airway injuries
non rebreather mask prepare for endotracheal intubation
breathing
observe WOB, O2 sat
exposure
observe entire body surface area
2nd degree deep partial thickness characteristics
pallor/erythema prolonged blanching edema decreased moistness
GI
paralytic ileus curling stress ulcers -> anti ulcer medications
TBSA is used to calculate the percentage of the burned area for what type of burns?
partial and full thickness
2nd degree burns are
partial thickness
pain
pharmacologic methods necessary to ensure patient comfort and decrease O2 demand
burns and hyperkalemia
potassium shifts into serum
AKI
prerenal from hypovolemic shock -> decreased perfusion
joint burns
promote ROM
3rd degree full thickness burns characteristics
range of colors from pale yellow to red, white, brown, or black may see eschar dry, leathery lack of sensation
debridement
removal of loose skin, nonviable tissue with sterile scissors avoid disruption of new granulation tissue
renal
risk for AKI decreased CO and renal perfusion myoglobinuria
metabolic
severe burns associated with hypermetabolism, physiologic stress, and inflammation
cardiac arrythmias
shifts of electrolytes (potassium) electrical burns cardiac monitoring
initial resuscitative wound care
stop burning phase head to toe evaluation (ABCDE) evaluation for potential transfer to burn center fluid resuscitate pain medications cleansing of wound with sterile saline or mild soap
1st degree burn example
sunburn
1st degree burns are
superficial
3 types of burns
superficial (1st degree) partial-thickness (2nd degree) full thickness (3rd degree)
2nd degree (partial thickness) subcategories
superficial partial thickness deep partial thickness
TBSA can determine
the extent of the injury
types of debridement
mechanical biodebridement: maggots chemical surgical
edema peaks in _____ hours, meaning the patients neck and face may swell more after admission. this is important when considering airway and intubation
48
adequate UO
0.5mL/kg/hr 30-50mL/hr
the patients palm represents _____% of his or her body surface
1%
parkland formula fluid estimation schedule
1/2 of total in first 8 hours 1/4 in second 8 hours 1/4 in third 8 hours
if more than ____% of the body surface is burned, consider transferring patient to a burn center
10%
fluid resuscitation
LR or isotonic fluids crystalloid infusion dependent upon urine production and hemodynamic status parkland formula to guide resuscitation
why are full thickness burns not as painful?
burned off neurons
acute rehabilitative wound care
cleansing of wounds with water and mild soap to remove exudate and devitalized tissue debridement
circulation
concern for hypovolemic shock vascular to third space
airway
consider face and neck edema, inhalation burns
myoglobinuria
damaged muscle tissue from burns, very nephrotoxic maintain adequate UO to prevent injury related to myoglobin
2nd degree deep partial thickness burns exhibit more ______ characteristics
dry
neuro
effects more common in electrical burns altered LOC, seizures, peripheral nerve injuries, memory problems, muscle weakness effects can be acute or delayed
2nd degree deep partial thickness involves
epidermis and extends deeper into dermis
2nd degree superficial partial thickness involves
epidermis and upper portion of dermis
3rd degree full thickness burns involve
epidermis, dermis, and subcutaneous laters of skin and tissue
1st degree superficial burns characteristics
erythematous blanches tingling, increased sensitivity to area heals within a week
3rd degree burns are
full thickness
rehabilitation goals
minimization of adverse effects promotion of functional ability psychosocial wellbeing social integration
cardiovascular management
hemodynamic instability fluid resuscitation cardiac arrhythmias
post 36 hours the body is in a state of
hypermetabolism -> hyperglycemia increased nutritional needs (increase calories)
first 24-36 hours of injury the body is in a state of
hypometabolism
why might a burn patient experience hemodynamic instability?
hypovolemic shock
nutrition
increased nutrition to meet hypermetabolic needs
1st degree superficial burns involves
intact epidermis
TBSA
total body surface area
2nd degree superficial partial thickness burns exhibit more _______ characteristics
wet
