Ethics In The Surgical Intensive Care Unit
102 ETHICS IN THE SURGICAL INTENSIVE CARE UNIT
Ricardo J. Gonzalez M.D.
1. What are the four principles of medical ethics?
1. Beneficence describes the active role of doing good by intervention.
2. Nonmaleficence is equivalent to saying, “First do no harm.”
3. Autonomy accounts for informed consent, competence, and the patient’s right to refuse treatment and to know what’s going on.
4. Justice means that all patients should receive fair and equal care but that one patient’s care should not squander limited resources for others.
2. What is a do-not-resuscitate (DNR) order?
Show answer
A DNR order instructs the surgeon not to resuscitate the patient if cardiopulmonary arrest occurs; however, a DNR order is much more involved and complicated than the acronym would have you believe. DNR is not absolute.
The Joint Commission for the Accreditation of Healthcare Organizations mandates that hospitals have written guidelines that promote accountability for DNR orders. All DNR orders must be documented in writing, similar to all other orders, in the appropriate section of the patient’s chart. They should specify the treatments to be withheld and treatments that the patient wishes to have implemented. Patients and families must participate in the DNR decision. Moreover, the DNR status should be discussed and reviewed with the other members of the health care team. Finally, a DNR order does not mean that the patient should be medically abandoned.
3. What is the difference between withdrawing and withholding support?
Show answer
A decision to withdraw should not be more problematic than a decision to withhold, because one cannot be sure that an intervention will work until you try it. There is no moral or ethical distinction between withdrawal and withholding of support. Either of the two allows natural progression of disease without the interface of medical technology. The decision to withdraw or withhold support does not equate with patient death, although the probability of death may be greater. After the decision has been made, appropriate management should focus on the patient’s comfort and psychosocial support.
4. What is an advance directive?
Show answer
An advance directive is a method of delineating a competent patient’s wishes for application at a time when he or she is no longer competent. Medical management or the lack thereof can be based on the patient’s wishes rather than a perceived sense of what is best for the patient. Advance directives may be an informal document, such as a living will, or a formal legal document, such as medical durable power of attorney.
5. What is durable power of attorney?
Show answer
A durable power of attorney is a patient-appointed proxy decision maker. The proxy decision maker becomes active as soon as the patient is no longer able to make competent medical decisions. Hence, the durable power of attorney must have been established in advance of the cognitive decline of the patient.
6. What is a living will?
Show answer
A living will, much like a durable power of attorney, is a formal advanced directive in which a competent patient produces a pre-illness guideline for future care in accordance with his or her wishes.
7. What is included in informed consent?
Show answer
Information about the patient’s condition as well as risks and benefits of the recommended treatment are included. Moreover, the operative and nonoperative alternatives (including no treatment) should be discussed with the patient. The patient’s understanding of the information and alternatives should be assessed as part of the informed consent. Finally, informed consent is a voluntary decision made by the patient or on behalf of the patient by a proxy decision maker.
8. What are futile care and medical futility?
Show answer
Ultimately, old age and disease will conquer us all. The definition of medically futile or inappropriate treatment is still debated. Nonetheless, there are four main concepts of medical futility:
1. Health care professionals are not required to provide physiologically futile treatment.
2. Imminent demise argues against treatment if the patient has no likelihood of survival to discharge.
3. Under the concept of lethal condition, medical care is considered futile if the patient will survive temporarily but ultimately expire as a result of the ongoing disease process.
4. Quality of life or qualitative futility argues against treatment if the patient’s quality of life is so poor that it would be unreasonable to prolong life.
Care must be taken, however, in making medical decisions based on futility because these decisions may lead to self-fulfilling prophecies.
9. What are the clinical determinants of brain death?
Show answer
Many of the current concepts of brain death are based on the 1968 report from the ad hoc committee at Harvard Medical School, which called for a new neurologic definition of brain death. But it was not until 1981 that BEMAT justified the neurologic criteria of brain death by stressing the need for intact brainstem integrative function in order for a person to function as a whole. By definition, brain death requires loss of brainstem reflexes in an irreversibly comatose patient. Brain death includes loss of the pupillary, corneal, oculovestibular, oculocephalic, oropharyngeal, and respiratory reflexes for ≥ 6 hours. The patient also should undergo an apnea test, in which the pCO2 is allowed to rise to at least 60 mmHg without coexistent hypoxia. The patient should be observed for the absence of spontaneous breathing. Other ancillary tests are not essential; for example, it is not necessary to perform an intravenous radioisotope cerebral angiogram or a four-vessel contrast cerebral angiogram or to document an isoelectric (”flat”) electroencephalogram.
Of note, all of the above criteria for brain death require the absence of central nervous system depression caused by barbiturates, narcotics, or hypothermia.
10. What is a persistent vegetative state?
Show answer
In a persistent vegetative state, typically seen after improvement of a comatose state, the patient lies motionless and without activity. The patient appears to be awake but does not have awareness of his or her surroundings or higher mental activity. Other names for this entity are coma vigil and akinetic mutism.
11. What is euthanasia?
Show answer
Euthanasia requires that the physician play an active role in assisting in the death of the patient. The concepts of physician-assisted suicide and active and passive euthanasia are highly controversial. In 1992, the Society of Critical Care Medicine published the results of a survey of critical care specialists; 87% had withdrawn life-prolonging support from patients. In addition, the most recent U.S. law pertaining to assisted suicide was passed in Oregon in 1994. This law makes it legal for a physician to prescribe medication to terminally ill patients for the purpose of committing suicide.
12. Who should approach patients’ families about organ donation?
Show answer
Some claim that the physician who has established good rapport with the patient’s family should raise the issue of organ donation. Others believe that the local organ procurement personnel should approach the family because they have greater interest and training in the process. The best approach is probably a combined one.
13. What should patients’ families be told when organ donation is feasible?
Show answer
The surgeon should stress that the patient has died despite an actively beating heart. The family should be questioned about the patient’s wishes regarding organ donation. All topics should be based on the concepts of informed consent. The family should be informed of the likelihood that several patients will benefit from the donated organs. The family needs to understand that there is no guarantee that the organs will be suitable for donation. They should be assured that they are not responsible for the cost of care provided after brain death is determined and that they may refuse organ donation without fear of prejudice.
14. What is the role of the hospital ethics committee?
Show answer
The hospital ethics committee educates hospital staff members, creates policy, and provides a source of consultation.
The function of education is accomplished through grand rounds, seminars, special lectures, and journal clubs. The hospital ethics committee should be viewed as an intrinsic part of the hospital community. Developed policies should be reviewed by other committees and divisions of the hospital to foster a better sense of cohesiveness when ethical and moral dilemmas arise. The consultative function of the ethics committee produces the greatest amount of controversy. In fact, many hospitals negate this function by stating that it interferes with the physician-patient relationship. The hospital ethics committee can and should provide an arena for collaboration and general ethical education within the hospital.
