ABSTRACT
BACKGROUND: Electrocution is an uncommon cause of death and occurs commonly due to accident. Deaths
caused by the passage of electric current, irrespective of the source of such current are described as electrocution.
The severity caused due to electrocution could extend from simple to severe shock leading to death of a person. Most
of the victims of high- tension electrocution die at the scene or declared dead before treatment. In first case report,
deceased having fatal electric shock brought to casualty & declared dead.In second case report, deceased fell down
from height due to electric shock &resulting in head injury.
Keywords: electrocution, high voltage electrocution, charring, wound of entry and exit.

mortality rate. In this case report we are
presenting two cases of death due to fatal
electrocution which highlights some of the
typical features of electrocution due to
high voltage such as massive destruction
of soft tissue along with exposure of
underlying bone.
Case Report no 1:
A 14yrs old boy was brought to casualty
with history of electric shock while
playing cricket. He was declared dead at
casualty before treatment and dead body
was sent for post-mortem examination.
After receiving accidental death report
from investigating agency and history
obtained from relatives and eye witnesses,
it was prima facie concluded by us that it
was a case of death due to electrocution.
The deceased was playing cricket in the
vicinity of two high tension electric wires.
While playing, the ball got entangled on
the top portion of a truck. The deceased
climbed up the truck to remove the ball. At
that time, there occurred physical contact
with high voltage wires and he got
electrocuted.
On external post-mortem examination, we
noticed the clothes were burnt, at the site
of electrical injuries. Singing of scalp
hairs, eyebrows, eyelashes were present.
Multiple wounds of electrocution were
present over the dead body as follows. 1)
Wound of electrocution over face at the
level of lower jaw and extending backwords covering the right lateral neck
region and reaching up to lower border of
right scapula. It was bone deep. Gross

INTRODUCTION
Deaths caused by the passage of electric
current, irrespective of the source of such
current are described as electrocution1.
Electrocution is an uncommon cause of
death and occurs commonly due to
accident2
Electricity has astonishingly very good
importance in human’s life. One cannot
believe to live without electricity. But we
as human being should not overlook the
pro’s&con’s of electricity in our life. The
endangerment of electricity varies from
simple harmless shock to severe muscle
contraction, unconsciousness and death.
Sometimes the victims may be thrown to
ground causing more fatal injuries. The
first electrical fatality was recorded in
France in 1879 when a stage carpenter was
killed by an alternating current (AC) of
250 volts3.
In India voltage supply for domestic use
electricity is around 220 to 240volts.
Electrocution results when a person
exposed to fatal amount of electricity and
it involves both high voltage (> 600 to 750
V) and low voltage (<600V) currents4.
Injuries from high voltage electrocution
