Bioethics in Medicine, Exemplified by the Karen Ann Quinlan Case

877 Words2 Pages

It is accepted that the advances in resuscitation techniques, initiated and influenced the evolution of bioethics by bringing to the fore the questions of:

(i) just allocation of scarce medical resource, health care

(ii) the nature of “being”, and

(iii) the proper purpose of medicine.

The main issues that caused the emergence, or the study and introduction of bioethics was the introduction of modern technology in medicine in the form of respirators and artificial heart machines. The media attention to the Karen Ann Quinlan case made the issues public. The Karen Ann Quinlan case serves as a perfect example of these new issues. She was diagnosed with a persistent vegetative state, and her life was sustained with a respirator and feeding tubes. Her parents wanted to remove the respirator. Many issues were brought forward during the deliberation; all of them dealing with issues pertinent to ethical medical practices:

(i) What is the difference between ordinary and extraordinary care in treatment?

(ii) Does an individual have the, “right to die”?

(iii) What is informed consent?

(iv) Who has the right to be a surrogate in the absence of consciousness in an individual?

(v) Who has the patient’s best interests at heart?

(vi) Is it important to have a “living will”, an advance directive, that formally states our wishes regarding medical treatment in the case of an unforeseen catastrophic illness?

Due to the use of resuscitation machines breath was no longer the sign of real life. This impelled the development of a new way of identifying death…brain death. ‘Brain death’, - the bodily condition of showing no response to external stimuli, no spontaneous movements, no breath, no reflexes, and a flat reading on a machine that...

...coined from the Harvard Medical School in 1968. Death was now seen to be a destruction of the brain, and not the termination of breathing. Karen Quinlan was not completely ‘brain dead’.

II) The, ‘Right to die’.

Can someone demand to be allowed to die? In most cases, the rational adult has the right to refuse treatment. This is sometimes ignored when the refusal will lead to death. However, at the same time there is never a right to invade the privacy of a patient by forcing treatment on them.

III) What is the extent of the doctor’s duty to his patient?

Individuals are inflexible in their opinions on these issues, especially in regards to life and death. The Karen Ann Quinlan case led society to see that a difference is made only when the issues are openly discussed. Bioethics seeks to provide the framework for such discussions to take place.
