2. DEFINITION
īĸ An electrical injury occurs when a current passes
through the body, interfering with the function of
an internal organ or sometimes burning tissue.
īĸ Electrical injuries (electrocution, electrical shock,
electrical burns, and electrical trauma) have
become a more common form of trauma with a
unique pathophysiology and with high mortality.
3. BASIC PHYSICS
Ohmâs Law: đŧ =đ/ đ
īĸI â current (Amps)
īĸV â voltage (Volts)
īĸR â resistance (Ohms)
īĸCurrent = volume (or number) of electrons
flowing between 2 points per second
īĸVoltage = the force that drives the
electrons across the potential difference
īĸResistance = the hindrance to flow
4. īĸThe amount and type of damage caused
to the body by electricity depend on :
Type of Current (AC or DC)
Amount of current (Amperage)
Voltage
Resistance (Ohms)
Duration of event
Route of current
5. īĸ There are two Types of current :
Direct current (DC): is the unidirectional
flow of electric charge. Direct current is
produced by sources such as batteries .
Alternating current (AC): is the flow of
electric charge periodically reverses direction.
6. īĸ The minimum current a human can feel
depends on the current type (AC or DC) and
frequency.
īĸ Alternative Current (AC) is more dangerous
than Direct Current (DC) at lower amperage as
it is more likely to cause cardiac arrhythmias.
7. īĸAlternative Current also causes
tetanic spasm of muscles of hand,
preventing the victim from
releasing his/her grasp.
īĸAlternative current is more likely
to cause death an estimated four
to six times than Direct Current.
8. Amount of
current(mA)
Effect
1mA Barely perceptible tingle
16 Current can be grasped
and released
16-20 Muscular paralysis
20-50 Respiratory paralysis
50-100 Ventricular fibrillations
>2000 Ventricular standstill
9. īĸ Voltage is a measure of the difference in
electrical potential between two points and is
determined by the electrical source.
īĸ Electrical injuries are conventionally divided into
high or low voltage using 500 or 1000 V as the
most common cut point.
īĸ The higher the voltage the more is tissue
distruction.
īĸ No fatalities with low voltage
10. RESISTANCE (OHMS)
īĸTendency of a material to resist the flow of
electric current.
īĸSpecific for a given tissue, depending on its
moisture content, temperature, and other
physical properties.
īĸ The higher the resistance of a tissue to the
flow of current, the greater the potential for
transformation of electrical energy to
thermal energy.
11. īĸ Nerves, muscle and blood vessels, because of
their high electrolyte and water content, have a
low resistance and are good conductors.
īĸ Bone, tendon, and fat, which all contain a large
amount of inert matrix, have a very high
resistance and tend to heat up and coagulate
rather than transmit current.
īĸ The other tissues of the body are intermediate in
resistance (eg. dry skin)
12. DURATION OF CONTACT/EVENT
īĸThe longer the duration of contact
with high-voltage current, the greater
the electro thermal heating and
degree of tissue destruction.
13. ROUTE OF CURRENT
īĸ The pathway that a current takes determines the
tissues at risk, the type of injury seen, and the
degree of conversion of electrical energy to heat.
īĸ Current passing through the heart or thorax can
cause cardiac dysrhythmias and direct
myocardial damage.
īĸ Current passing through the brain can result in
respiratory arrest, seizures, and paralysis.
īĸ Current in proximity to the eyes can cause
cataracts.
14. īĸThe amount and type of damage caused
to the body by electricity depend on :
Type of Current (AC or DC)
Amount of current (Amperage)
Voltage
Resistance (Ohms)
Duration of event
Route of current
15. ETIOLOGY
īĸ Children- at home with extension cords (60-
70%)
īĸ Adult- workplace and constitute the fourth
leading cause of work-related death.
īĸ More than 50% of the occupational
electrocutions result from power line contact,
and 25% result from electrical tools or
machines.
īĸ Male-to-female ratio is 9:1
16. SPECIFIC CAUSES OF ELECTRICAL
INJURIES (CLASSIFICATION)

voltage
injuries
2.High
voltage
injuries
3.Lightning
injuries
4.Other
electrical
injuries
17. LOW-VOLTAGE INJURIES( LOW-TENSION
INJURIES)
īĸCaused by voltage less than 1000 V.
īĸIncludes most injuries caused by
household current;
īĸThe child who bites into the cord
producing lip, face and tongue injuries
as well as occupational injuries
resulting from the use of small power
tools.
18. LOW-VOLTAGE INJURY: REPRESENTATIVE ELECTRIC FIELD
LINES AND ISOPOTENTIAL LINES ESTABLISHED IN THE LOWER
FACE DURING ORAL CONTACT WITH A HOME POWER CORD.
19. HIGH-VOLTAGE INJURIES
/HIGH TENSION INJURIES
īĸResult of exposure to 1000 V or more.
īĸThese injuries are often the result of
occupational exposure to outside power
lines .
īĸCommonly occur when a conductive
object touches an overhead high voltage
power line.
22. LIGHTNING INJURIES
īĸ Involve voltages higher than those of the other
injuries.
īĸ Involves energy with high voltage and high
amperage but extremely short duration.
īĸ Lightning is usually a unidirectional massive
current impulse.
īĸ The largest flow of current tends to jump to the
ground before much of it passes through the
body.
23. ī§ Rare pathognomonic
âflowerlikeâ branching
skin lesions in persons
struck by lightning.
ī§ Caused by âflashoverâ
effect of non penetrating
current.
24. OTHER ELECTRICAL INJURIES
īĸIntentional injuries include those due
to the use of high-voltage devices for
rapid incapacitation, child and or
spouse abuse, and torture.
īĸAlso, the use of skin electrodes in
medicine can cause burn.
25. TYPES OF ELECTRICAL BURNS
īĸ Depending on the voltage, current, pathway, duration of
contact, and type of circuit, electrical burns can cause a
variety of injuries through several different mechanisms.
1. Direct contact (low and high voltage)
2. Indirect contact
a. Electric arcs
b. Flame
c. Flash
26. 1. DIRECT CONTACT
īĸ Current passing directly through the body will heat the
tissue causing electro thermal burns, both to the surface
of the skin as well as deeper tissues, depending on their
resistance.
īĸ It will typically cause damage at the source contact point
and the ground contact point.
27. INDIRECT CONTACT
A. ELECTRICAL ARCS
o A current spark formed between two objects of differing
potential that are not in contact with each other, usually
a highly charge source and a ground.
īĸ Because the temperature of an electrical arc is
approximately 2500° C, it is most destructive indirect
injury.
īĸ It causes very deep thermal burns at the point where it
contacts the skin.
28.
29. 2. INDIRECT CONTACT
B. Flame: Ignition of clothing causes
direct burns from flames.
C. Flash: When heat from a nearby
electrical arc causes thermal burns but
current does not actually enter the body.
30. MECHANISM OF INJURY
1. Electrical energy cause direct tissue damage,
alter cell membrane resting potential, and elicit
tetany.
2. Conversion of electrical energy into thermal
energy, causing massive tissue destruction and
coagulation necrosis.
3. Mechanical injury with direct trauma resulting
from falls or violent muscle contraction.
31. CONT..
īĸThe most common entry point for electricity
is the hand; the second most common is
the head.
īĸThe most common exit point is the foot.
īĸA current that travels from arm to arm or
from arm to leg may go through the heart
and is much more dangerous than a current
that travels between a leg and the ground.
32. CONTâĻ
īĸ Electrical current through the head or thorax
is more likely to produce fatal injury.
īĸ A current that travels through the head may
affect the brain.
īĸ Transthoracic currents can cause fatal
arrhythmic cardiac damage, or respiratory
arrest.
īĸ Tissues differ in susceptibility to electrical
damage.
33. BODYâS RESPONSE TO BURN
Described by Jackson in 1947.
īĸ Zone of coagulationâOccurs at the point of maximum
damage. There is irreversible tissue loss due to coagulation
of the constituent proteins.
īĸ Zone of stasisâ Characterized by decreased tissue
perfusion.
īĸ Zone of hyperemiaâOutermost zone tissue perfusion is
increased. Tissue will invariably recover unless there is
severe sepsis or prolonged hypo perfusion.
36. Pattern of injury/Tissue damage.
Organ Tissue damage
Brain Seizure, hemorrhages, poor short-term
memory, unconsciousness, ischemia,
personality changes, irritability, difficulty
sleeping.

Immediate Care:
Within 12 hours of injury, wound care consist:
īĸ Covering the wound with sterile towel.
īĸ Placing clean, dry sheets and blanket over the client
īĸ Cleansing and gentle debridement of devitalized tissue in
hydrotherapy and cart shower.
īĸ Removal of any damaging agents ( e.g.: chemical tar)
and application of any topical agents and a dressing.
īĸ Wash with mild soap and rinse thoroughly with warm

īĸ Careful use of scissors and
forceps to lift and trim away
devitalized tissue.
īĸ Wet to dry dressing change.
īĸ Coarse gauze dressing
saturated with a prescribed
solution(Parrafin or
petroleum), applied to the
wound and leave for 6-
8hours.
76. īĸ Enzymatic debridement:
Application of commercially prepared proteolytic and
fibrinolytic topical enzyme (eg. Papain) to the burn
wound.
īĸ Surgical Debridement:
ī Tangential excision â very thin layers of devitalized
tissue are sequentially shaved until viable tissue is
reach.
.
77. GRAFTING
īĸAutograft: Coverage of the burn wound with a
graft of the patientâs own skin (autograft).
Biologic dressings
īĸ Homograft - Homograft are skin obtained from
living or recently deceased humans.
īĸ Heterografts - Heterografts consist of skin
taken from animals (usually pigs)
78. CARE OF DONOR SITE
īĸA moist gauze dressing is applied at the
time of surgery to maintain pressure and to
stop any oozing.
īĸThe donor site may be treated in several
ways, from single-layer gauze impregnated
with petrolatum, scarlet red, or bismuth to
new biosynthetic dressings such as
Biobrane or BCG Matrix.
79. īĸ Donor sites must remain clean, dry, and free
from pressure.
īĸ Because a donor site is usually a partial-
thickness wound, it will heals spontaneously
within 7 to 14 days with proper care.
īĸ Donor sites are painful, and additional pain
management must be a part of the patientâs
care.
CARE OF DONOR SITE
80. CARE OF THE PATIENT WITH AN
AUTOGRAFT
īĸ Occlusive dressings are commonly used initially after
grafting to immobilize the graft.
īĸ Immobilize newly grafted areas to prevent dislodging the
graft.
īĸ Homografts, heterografts, or synthetic dressings may also
be used to protect grafts.
īĸ The graft may be left open with skin staples to immobilize
it, which allows close observation of progress.
īĸ The first dressing change is usually performed 3 to 5 days
after surgery, or earlier in the case of purulent drainage or
a foul odor.
81. īĸ If the graft is dislodged, sterile saline compresses will help
prevent drying of the graft until the physician reapplies it.
īĸ The patient is positioned and turned carefully to avoid
disturbing the graft or putting pressure on the graft site.
īĸ If an extremity has been grafted, it is elevated to minimize
edema.
īĸ The patient begins exercising the grafted area 5 to 7 days
after grafting.
CARE OF THE PATIENT WITH AN
AUTOGRAFT
82. BIOSYNTHETIC AND SYNTHETIC DRESSINGS
īĸ BIOBRANE - composed of a nylon, Silastic membrane
combined with a collagen derivative.
īĸ BCG Matrix - This dressing combines beta-glucan, a
complex carbohydrate, with collagen in a meshed
reinforced wound dressing.
īĸ Other synthetic dressings used for burn wounds include
Tegaderm, N-Terface, and DuoDerm.
83. TOPICAL ANTIMICROBIAL
TREATMENT
īĸ Open Method:
After application of antimicrobial cream, it is left open
without gauze dressing and reapplied as needed.
īĸ Closed Method:
âĸ Gauze dressing is impregnated with antimicrobial and
applied to the wound.
âĸ Wrap from the most distal to proximal direction.
âĸ Temporary wound coverings.
84. ANTIMICROBIAL
īĸ Bacitracin âInterruption of cell wall
synthesis.
īĸ Cerium Nitrate Silver Sulfadiazine-
Similar to that of silver sulfadiazine or
silver nitrate
īĸ Gentamicin -Binds irreversibly to the
30s ribosome and inhibits protein
synthesis
85. ANTIMICROBIAL
īĸ Mafenide Acetate -antibacterial
activity against most Gram-
positive species, including
clostridia.
īĸ Mupirocin (Bactroban) -
inhibition of protein synthesis.
īĸ Nitrofurazone- it inhibits several
bacterial enzymes involved in
carbohydrate metabolism. It is
bactericidal.
86. ANTIMICROBIAL
īĸ Povidone Iodine (Betadine)
īĸ Silver Nitrate 0.5% -
Bacteriostatic at lower
concentrations (0.5%) and
bactericidal at higher
concentrations (10%).
īĸ Silver Sulfadiazine - Impair
bacterial DNA replication
88. REHABILITATION PHASE
Goal:
īĸ Maximize functional capacity, minimize functional loss and
maximize emotional recovery.
The rehabilitation for patients with burn injuries starts from the
day of injury, lasting for several years and requires
multidisciplinary efforts. A comprehensive rehabilitation
programmed is essential to decrease patientâs post traumatic
effects and improve functional independence.
89. PRINCIPLES OF BURN
REHABILITATION
īļ The program should start early, preferably the day of injury.
īļ A program of care should be avoid prolonged periods of
immobility, and any body parts that is able to move freely
should be moved frequently.
īļ Range of motion exercise should be started the day of injury.
īļ There should be planned program of daily activity and
rehabilitative care. The plan should be reviewed daily as
rehabilitative needs change.
91. HYPERTROPHIC SCAR
īĸ These are Characterized
by an over abundant
formation of matrix,
especially collagen, in
wounds that heal by
granulation.
92. KELOIDS
īĸ A large heaped-up mass of
scar tissue, a keloid may
develop and extend beyond
the wound surface
93. īĸFailure to heal
īĸFailure of the wound to heal result from many
factors, including infection, an underlying
disease process, shearing, pressure or
inadequate nutrition.
94. īĸContractures
īĸ The burn wounds tissue
shortens because of the force
exerted by the fibroblasts and
the flexion of muscles in natural
wound healing.
95. RECONSTRUCTION SURGERIES
īļ The surgical plan involves recreating the initial tissue loss
and then adding appropriate tissue.
The techniques are -
īļ Direct closure
īļ Grafts
īļ Flaps
īļ Expanded skin
96. DIRECT CLOSURE
īļ Direct closure in burn reconstruction is the simplest form of
scar revision following excision of the scar.
97. SKIN GRAFTING
īļ Split or partial thickness
graft-includes epidermis and
part of dermis
īļFull thickness graft-
includes epidermis and full
thickness of the dermis
īļ Composite graft- includes the
full thickness of the skin and a
portion of the underlying tissue
such as subcutaneous tissue,
muscle, cartilage or bone.
98.
99. FLAPS
īļA skin flap is a segment of skin and
subcutaneous tissue which is
transferred from its original position
on the body to another site while
maintaining its own inherent
vasculature for nourishment.
100.
101. COMMON POST BURN CONTRACTURES AND THE RESPECTIVE
ANTI- CONTRACTURE POSITION OF NURSING.
īļ The flexion contracture of the neck can be avoided by
having a pillow under the shoulder and nursing with the
neck in extension
102. īļ The Extension contracture of the neck can
be avoided by sitting with head in flexion
and lying with pillows behind the head.
103.
104. īļ Clawing of fingers can be avoided by keeping the M.P
joints in flexion. IP joints in extension, thumb mid
palmer radial abduction.
105. īļ The thumb and palm deformity is avoided by keeping
the wrist extended with minimal MCP flexion and
keeping the fingers extended and thumb abducted.
106. īļ Flexion contracture
of knee can be
avoided by keeping
the legs extended in
lying and sitting and
by using knee
extension splints.
111. SILICONE
īĸ Silicone is another modality
used to treat hypertrophic
scarring.
īĸ It is likely to influence the
collagen remodeling phase of
wound healing.
112. PSYCHOLOGICAL IMPACT
īļ Reassurance
īļ Demonstrate genuine empathy and compassion
īļ Active listening
īļ Providing adequate information
īļ Answering their questions
113. SOCIAL REHABILITATION
īĸ Individuals should be encouraged in order to re-establish
themselves in their social and vocational lives as soon as they
are able to, and their family members should be encouraged
to promote this behavior.
īĸ Life after a burn injury, particularly a major injury can take
some significant adjusting to however with the right support
and rehabilitation, burn injured patients can lead a full life.
114. īĸ Acute pain related to destruction of skin and tissue as
evidenced by pain score of 4.
īĸ Hyperthermia related to infection as evidenced by temperature
of 101.1 degree F, moderate pus cells, scanty growth in wound
swab, TLC of 18.900 thousands.
īĸ Fluid volume deficit related to loss of fluid through burn wound ,
restricted oral intake as evidenced by tachycardia, dry lips, dry
skin.
īĸ Imbalanced nutrition less than body requirement related to
hyper metabolic state, protein catabolism as evidenced by
negative protein and calorie balance, deranged LFT.
115. īĸ Impaired skin integrity related to disruption of skin
surface as evidenced by absence of viable tissue.
īĸ Impaired physical mobility related to limb immobilization,
restrictive therapies as evidenced by limited ROM.
īĸ Risk for electrolyte imbalance related to muscle and
tissue breakdown.
īĸ Risk for infection related to destruction of skin barrier,
environmental exposure.
īĸ Risk for ineffective tissue perfusion related to interruption
of arterial and venous blood flow.
116. īĸ Anxiety related to threat of disfigurement,
hospitalization.
o Risk for ineffective airway clearance, pneumonia
related to prolonged bed ridden.
īĸ Disturbed body image related to dependent client
role, traumatic event.
īĸ Risk for complications ( compartment syndrome,
local infection, neurologic injury, DVT, arrhythmia)
related to electric injury.
īĸ Knowledge deficit regarding the treatment regimen.
Trueâ high tension injuries. There is extensive tissue damage and often limb loss. There is usually a large amount of soft and bony tissue necrosis. Muscle damage gives rise to rhabdomyolysis, and renal failure
âFlashâ injury can occur when there has been an arc of current from a high tension voltage source. The heat from this arc can cause superficial flash burns to exposed body parts, typically the face and hands.
Zone of stasisâincrease tissue perfusion here and prevent any damage becoming irreversible. Additional insultsâsuch as prolonged hypotension, infection, or oedemaâcan convert this zone into an area of complete tissue loss.
These three zones of a burn are three dimensional, and loss of tissue in the zone of stasis will lead to the wound deepening as well as widening
The purposes of wound coverage are to decrease the risk for infection; prevent further loss of protein, fluid, and electrolytes through the wound; and minimize heat loss through evaporation.Â
Like biologic dressings, Biobrane protects the wound from fluid loss and bacterial invasion. Biobrane adheres to the wound fibrin, which binds to the nylonâcollagen material. Within 5 days, cells migrate into the nylon mesh
These devices are especially useful for partial thickness wounds that needed more than 2 weeks to heal and for the edges of grafted skin. Application of elastic pressure garments loosens collagen bundles and encourages parallel orientation of the collagen to the skin surface with the disappearance of the dermal nodules
After the graft heals, pressure dressings are implemented to assist in the prevention of conÂtractures and tight hypertrophy scars, which can inhibit moÂbility. These dressings also inhibit venous engorgement and edema formation in areas with decreased lymphatic outflow. Pressure dressings may be elastic wraps or specially deÂsigned, custom-fitted, elasticized clothing that provide conÂtinuous and uniform pressure over burned surfaces. Figure 2 illustrates such garments. For maximal effectiveness, pressure garments should be worn at least 23 hours a day, every day, until the scar tissue is mature (12 to 24 months). Pressure garments generally cause an increase in warmth and itchiness and often are seen as very uncomfortable by the client. The nurse must reinforce to the client that wearing pressure garments is extremely beneficial in maintaining moÂbility and reducing hypertrophy scarring.
