Brain Death - The Fatal
Phenomenon
Brain death is defined as
the irreversible loss of all functions of the
brain. It can be
determined in several ways.
No electrical activity in
the brain : this is determined by an EEG.
No blood flow to the brain
as determined by clinical assessment (no
movement, no response to
stimulation, no breathing, no brain reflexes.)
Causes of brain
death
Anoxia : caused by
drowning, respiratory diseases, or drug
overdose.
Ischemia :
Blockage of an artery leading to the brain or in
the brain, heartattack
(stoppage of the heart for a period of
time), bleeding in the brain.
Intracranial hematoma : caused by a head
injury (a blow to the head) or a ruptured
aneurism.
A gunshot
wound to the head : causes destruction of brain
tissue and swelling of the brain.
Intracarnial Aneurysm :
the balooning of a blood vessel supplying the
brain- can cut off blood supply or rupture.
Brain tumors : can destroy
brain tissue and increase pressure within the
brain.
When any
of the above occur, they cause swelling of the
brain. Because the brain is enclosed in the
skull, it does not have romm to swell, thus
pressure within the skull increases ( this is
intracarnial
pressure ). This can stop blood
flow to the brain, killing brain cells and
causes herniation of the brain (pushing the
brain outside of its normal space). When brain
cells die, they do not grow back, thus any
damage caused is permanent and irreversible.
Brain death & Liver
Transplantation 
The
patient who is a Brain dead Cadaver
can donate a whole liver . In western
countries, these procedures are being done
routinely for the last three decades
successfully. In India 'brain death' has been
accepted through an enacted law known as
Organ Transplantation Act
1994. It is also estimated that more
than 75,000 people meet with fatal accidents
every year in India; Because of the severity of
their injuries, about 50% of these people end up
Brain Dead
, even if they are still on life
support. The chance to use their organs to save
the lives of others has not even been
considered. The organs of such a brain dead
patient can save up to six lives when his eyes,
heart, liver, kidneys, intestines & pancreas
can be used in transplantation procedures. In
fact a single liver can be split into two and
can be transplanted into two persons at the same
time.
Consider a
person who is declared brain dead. He/she can
never exist without using life support machines
at all times and that too without regaining
consciousness. If the kith and kin realize the
importance of organ donation at this point of
time, then the person will continue to live in
the lives of others. The gift of rebirth can and
must be used..
A persons heart can
be still be beating because of the ventilator
and medications keep the blood pressure normal.
A person who is
declared brain dead is legally
dead.
