ENCYCLOPÆDIA BRITANNICA
Bioethics
The issues of abortion and euthanasia
are included in one of the fastest growing
areas of applied ethics, that dealing
with ethical issues raised by new
developments in medicine and the
biological sciences. This subject, known as
bioethics, often involves
interdisciplinary
work, with physicians, lawyers,
scientists, and theologians all
taking part. Centres for research in bioethics have
been established in Australia, Britain,
Canada, and the United States. Many
medical schools have added the discussion
of ethical issues in medicine to their
curricula. Governments have sought
to deal with the most controversial issues by
appointing special committees to
provide ethical advice.
Several key themes run through the
subjects covered by bioethics. One, related
to abortion and euthanasia, is whether
the quality of a human life can be a reason
for ending it or for deciding not
to take steps to prolong it. Since medical science
can now keep alive severely disabled
infants who a few years ago would have died
soon after birth, pediatricians
are regularly faced with this question.
The issue
received
national publicity in Britain in 1981 when a respected pediatrician
was
charged with murder, following
the death of an infant with Down's syndrome.
Evidence at the trial indicated
that the parents had not wanted the child to live
and that the pediatrician had consequently
prescribed a narcotic painkiller. The
doctor was acquitted. #
The following
year,
in the United States, an even greater
furor was caused by a doctor's decision
to follow the wishes of the parents of a
Down's syndrome infant and not
carry out surgery without which the baby would
die. The doctor's decision was upheld
by the Supreme Court of Indiana, and the
baby died before an appeal could
be made to the U.S. Supreme Court. In spite of
the controversy and efforts by government
officials to ensure that handicapped
infants are given all necessary
lifesaving treatment, in neither Britain nor the
United States is there any consensus
about the decisions that should be made
when severely disabled infants are
born or by whom these decisions should be
made.
Medical advances have raised other
related questions. Even those who defend the
doctrine of the sanctity of all
human life do not believe that doctors have to use
extraordinary means to prolong life,
but the distinction between ordinary and
extraordinary means, like that between
acts and omissions, is itself under attack.
Critics assert that the wishes of
the patient or, if these cannot be ascertained,
the quality of the patient's life
provides a more relevant basis for a decision than
the nature of the means to be used.
Another central theme is that of
patient autonomy. This arises not only in the
case of voluntary euthanasia but
also in the area of human experimentation,
which has come under close scrutiny
following reported abuses. It is generally
agreed that patients must give informed
consent to any experimental procedures.
But how much and how detailed information
is the patient to be given? The
problem is particularly acute in
the case of randomly controlled trials, which
scientists consider the most desirable
way of testing the efficacy of a new
procedure but which require that
the patient agree to being administered randomly
one of two or more forms of treatment.
The allocation of medical resources
became a life-and-death issue when hospitals
obtained dialysis machines and had
to choose which of their patients suffering
from kidney disease would be able
to use the scarce machines. Some argued for
"first come, first served," whereas
others thought it obvious that younger patients
or patients with dependents should
have preference. Kidney machines are no
longer as scarce, but the availability
of various other exotic, expensive lifesaving
techniques is limited; hence, the
search for rational principles of distribution
continues.
New issues arise as further advances
are made in biology and medicine. In 1978
the birth of the first human being
to be conceived outside the human body
initiated a debate about the ethics
of in vitro fertilization. This soon led to
questions about the freezing of
human embryos and what should be done with
them if, as happened in 1984 with
two embryos frozen by an Australian medical
team, the parents should die. The
next controversy in this area arose over
commercial agencies offering infertile
married couples a surrogate mother who
would for a fee be impregnated with
the sperm of the husband and then surrender
he resulting baby to the couple.
Several questions emerged: Should we allow
omen to rent their wombs to the
highest bidder? If a woman who has agreed to
ct as a surrogate changes her mind
and decides to keep the baby, should she be
llowed to do so?
The culmination of such advances
in human reproduction will be the mastery of
genetic engineering. Then we will
all face the question posed by the title of
Jonathan Glover's probing book What
Sort of People Should There Be? (1984).
Perhaps this will be the most challenging
issue for 21st-century ethics.
