70 歲男士,末期癌症,神智清醒身心極度痛楚不時接受無效用的化療死時還施行心肺復甦慘不忍睹

為什麼不把安樂死合法化,讓病者可以安祥地離世?

Page 3: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Why should we not vote at this stage?

What do you mean when you say “euthanasia”?

Page 4: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

To relieve the suffering of the patient

provide good palliative care ( 紓緩冶療 ), including the provision of strong opioids, e.g. morphine

forgo ( 放棄 ) futile ( 無效用 ) life-sustaining treatment ( 維持生命治療 )

kill the patient by a lethal injection

Page 5: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Which option is classified as euthanasia?

Euthanasia could be defined narrowly or broadly

Page 6: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Medical and legal field: narrow definition

Page 7: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Medical Council of Hong Kong does not support euthanasia, which is defined as “direct intentional killing of a person as part of the medical care being offered”

The term refers to “active euthanasia”

Page 8: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

One says “Euthanasia is legalized in the Netherlands and Belgium”

The term refers to “voluntary active euthanasia”

Page 9: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

In public debates and in bioethics literature

forgoing life-sustaining treatment (LST) is often considered as one form of euthanasia, labeled as “passive euthanasia”

Page 10: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Problems

forgoing LST is legally acceptable in most parts of the world in appropriate situationswish of a mentally competent patient when the treatment is futile

active euthanasia is illegal in most parts of the world

Page 11: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

To avoid any unnecessary confusing connotations

the term “passive euthanasia” is not recommended by the medical and legal field

the term is not used in relevant guidelines and legislations

Page 12: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Forgoing LST is itself a complex ethical issue, and what

constitutes futility is not easy to define

non-controversial: forgoing cardiopulmonary resuscitation in a terminally ill

controversial: withdrawal of ventilator support in a conscious quadriplegic patient

Page 13: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

It would not help public discussion to lump all these together under the label of “euthanasia”

Page 14: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

To relieve the suffering of the patient

provide good palliative care ( 紓緩冶療 ), including the provision of strong opioids, e.g. morphine

forgo ( 放棄 ) futile ( 無效用 ) life-sustaining treatment ( 維持生命治療 )

kill the patient by a lethal injection

Page 15: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Case 1A patient with advanced incurable cancer is suffering from severe pain despite strong analgesics. He requests the doctor to kill him by a lethal injection.

What should the doctor do?

Page 16: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Basic question:

Could the pain of the patient be better controlled?

Page 17: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Comments:Pain and suffering of the great majority of

terminally ill patients could be controlled with appropriate palliative care.

Adequate pain control needs an appropriate choice and appropriate dose of analgesics, often with other modalities of treatment including psychological, social and spiritual support.

Failure to control pain usually means that the treatment is not optimal.

Page 18: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Next level of discussion:

In the rare situation where the pain of the patient is still not adequately relieved by optimal treatment, should the doctor kill the patient by a lethal injection?

Page 19: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Question redefined:Should euthanasia be legalized in

Hong Kong to allow killing of such patients?

Should the doctor kill this particular patient though euthanasia is illegal in Hong Kong?

Page 20: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Next level of discussion (optional):

Are there other alternatives to alleviate the suffering of the patient without resorting to killing?

Page 21: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Comments:Palliative sedation (terminal sedation)

could be used as a last resort to alleviate the suffering of a terminally ill patient.

The patient is given sedatives to reduce his awareness of the symptoms. However, the patient will become drowsy and his life will likely be shortened by this. It should be noted that the appropriate use of strong

analgesics like morphine does not shorten life. Palliative sedation is not the same as the use of strong analgesics.

Page 22: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Follow up question:

Is palliative sedation ethically justified?

How is palliative sedation ethically differentiated from euthanasia?

Page 23: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Comments:

One can discuss the principle of double effect here.

Page 24: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Case 2 (This should be used as a follow up discussion to case 1)A 30 years old quadriplegic patient with no hope of

recovery is living with his parents aged over 60. His lower limbs are totally paralyzed and he could

barely move his upper limbs. He is wheelchair bound and needs assistance in feeding.

The whole family is on CSSA. The healthcare team has arranged reasonable social support to the patient, including visits by members of patient groups. He has declined living in an institution because he wants to stay with his parents.

Page 25: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

He sees no hope in his future. He strongly feels that his existence is meaningless and a burden to his parents.

He has been assessed by a psychiatrist. He is clinically not depressed, but is suffering from existential distress.

He requests the doctor to kill him by a lethal injection. What should the doctor do?

Page 26: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Point to note:

In the Netherlands, patients eligible for euthanasia are not necessarily terminally ill, nor suffering from physical pain.

Page 27: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Question redefined:Should euthanasia be legalized in

Hong Kong to allow killing of patients who are not terminally ill and not suffering from physical pain?

Are there REALLY no other alternatives to alleviate the suffering of the patient without resorting to killing?

Page 28: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Comments:

One may refer to the book 我要安樂死 by 斌仔 and the website of 路向四肢傷殘人士協會 for discussion.

Case 3The son of a 70 years old terminally ill

unconscious patient is informed by the doctor that the patient will die soon, and the doctor recommends no cardiopulmonary resuscitation (CPR) when the patient dies, in order not to prolong the dying process. 

The son agrees with the doctor that it is meaningless to carry out CPR.

However, the daughter of the patient does not agree. She considers that, due to filial piety, life must be prolonged at all cost, and CPR must be done.

What should the son do?

Page 30: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Question redefined:How should one assess the best

interests of an unconscious patient?Does filial piety means that all

possible life-sustaining treatment must be given?

How should the final decision be made?

Page 31: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Comment:Approaches to questions 1 and 3 are

outlined in the Hospital Authority Guidelines on Life-sustaining Treatment.

Page 32: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Case 4A 60 years old patient is suffering from

severe chronic chest disease which has a relapsing course with a downhill trend.

After attending a public seminar on advance directives, the patient tells his son that he wants to make an advance directive, saying that he does not want intubation and mechanical ventilation when he has respiratory failure again.

Page 33: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

His son remembers that the patient had a previous episode of respiratory failure which was successfully treated by intubation and mechanical ventilation, and he does not agree to the decision of the patient.

The patient expresses that he had a lot of suffering during the past episode of intubation, and he prefers no further intubation. The patient understands that he will probably die by refusing such treatment in a relapse.

What should the son do?

Page 34: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Question redefined:The patient and the son have conflicting

views on this. Whose view is more correct?How should a final decision be made?If the patient finally makes a valid

advance directive stating his refusal of intubation and mechanical ventilation, could the son override the advance refusal when the patient goes into respiratory failure again?

Page 35: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Comments:Quality of life decisions are value laden,

and sometimes there is no absolute answer.

A properly informed mentally competent patient’s decision should be respected.

A valid advance refusal of life-sustaining treatment is legally binding, and should be followed in an applicable situation.

Page 36: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Case 5An infant with Down’s Syndrome suffers from

intestinal obstruction. A major operation could cure the obstruction.

His parents however refuse to sign consent for the operation, saying that the life of a child with Down’s Syndrome is miserable, and it is not worthwhile for the infant to go through the suffering of the major operation.

The infant will die without the operation. What should the doctor do?

Page 37: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Question redefined:Is the life of a child with Down’s

Syndrome miserable?What factors should the parents

consider when making the decision?Could the doctor override the

decision of the parents?

Page 38: Dr. TSE Chun-Yan Society for Life and Death Education November 2009

Comments:While it may be acceptable to forgo

complex surgery with poor outcome in infants with severe mental and physical disability, many people would consider that this case does not belong to this group.

If the doctor considers that the decision of the parents is not in the best interests of the infant, the case could be brought to the court.
