What is bioethics?
Bioethics is a field of study where issues of moral and ethical dimensions are addressed, which link research, decisions, conduct and procedures in the area of biology and medicine to the right to life.
The concept of bioethics is interdisciplinary and includes areas such as biology, law, philosophy, exact sciences, political science, medicine, environment, etc.
In Brazil, one of the main responsible for the expansion of this concept is the Brazilian Society of Bioethics (SBB), founded in 1995.
According to the Jornal do Cremesp published in April of the same year, the meeting that later culminated in the creation of SBB aimed at:
Encourage discussions in society on controversial topics such as abortion, euthanasia, assisted reproduction and genetic engineering and other problems related to life, death and human existence, but always aiming at the debate on ethical aspects.
The principles of bioethics
In the definition of bioethics, two issues predominate: biological knowledge and human values.
It is subdivided into basic principles that seek to solve ethical problems arising from the development of procedures with living beings of all species.
With regard to medical ethics, Hippocrates is a name that stands out. Considered the “father of medicine”, the Greek doctor used to combine medicine and philosophy.
The focus of his relationship with the patient was the good, and his approach was mainly guided by two principles: the principle of non-maleficence and the principle of beneficence.
1. Principle of non-maleficence
The principle of non-maleficence is based on the idea that no harm should be done to the other. Thus, no action is allowed that consists of intentional harm to guinea pigs or patients.
The principle is represented by the Latin phrase: primum non nocere (first, do no harm). It aims to prevent treatment or research from causing more harm than possible benefits.
Some scholars argue that the principle of maleficence is, in fact, part of the principle of beneficence, since the act of not causing harm to another is, in itself, a practice of good.
Bioethics example in the application of the principle of non-maleficence : In a research for the development of a vaccine, the testing phase in humans is reached.
The tests showed that in 70% of cases, patients who received the vaccine were cured, but 30% died as a result of side effects.
Studies will be interrupted and the vaccine will not be able to be produced despite a high cure rate, causing the death of people is causing harm and hurting the principle of non-maleficence.
2. Principle of beneficence
This principle consists of doing good; in virtue of benefiting others.
Thus, professionals working in the field of research and experiments must ensure the accuracy of the technical information they have and be convinced that their actions and decisions have positive effects.
Thus, it is expected that any act has the fundamental objective of good, never evil.
An example of bioethics in the application of the principle of beneficence : a doctor is helping a patient who is at risk of death. This patient is a well-known killer.
This doctor’s goal will always be to save her patient’s life and will mobilize all alternatives for that to happen.
According to the principle of beneficence, one should only look for the good. Neglect or omission (even if it could be justified) would consist of an evil and would hurt the bioethical principle.
3. Principle of autonomy
The central idea of this principle is that everyone has the capacity and freedom to make their own decisions.
Thus, any type of procedure to be performed on an individual’s body and / or related to his or her life, must be authorized by him.
In the case of children and the disabled, the principle of autonomy must be practiced by the respective family or by the legal guardian.
It is important that this principle is not practiced at the expense of the principle of beneficence; sometimes it needs to be disrespected so that one person’s decision does not harm another.
The principle of autonomy is supported by law, under the Brazilian Medical Code of Ethics (Chapter V, Article 31).
This article highlights the patient’s right to have his autonomy respected, in the following excerpt where it is indicated that the doctor is prohibited from:
(…) disrespect the right of the patient or his legal representative to freely decide on the execution of diagnostic or therapeutic practices, except in case of imminent risk of death
An example of bioethics in the application of the principle of autonomy : when a patient is diagnosed with a terminal illness, there are no treatments that can cure him. Generally, what is done in these cases is to give this patient palliative care, so that he feels relieved of the symptoms of the illness that affects him.
However, it is up to the patient to decide whether or not to proceed with these palliative care, since they do not make a cure possible; they only alleviate (sometimes) the harm of the disease.
It is up to the medical professional to respect the patient’s decision, if he does not want to receive such care.
4. Principle of justice
In the field of bioethics, this principle is based on distributive justice and equity.
He argues that the distribution of health services should be done fairly and that there should be equal treatment for all individuals.
Such equality does not consist in giving the same to everyone, but in giving to each one, what each needs.
An example of bioethics in the application of the principle of justice : a real case that exemplifies the principle of justice, happened in Oregon, in the United States.
In order to provide basic health care to a larger number of people, the local government has reduced health care costs that imply high costs.
Thus, it was possible to carry out a wider distribution of available resources in order to help solve the problems of a larger portion of the population.

What is bioethics for?
The application of the concept of bioethics aims to ensure that there is a moral responsibility in medical and biological procedures, research and acts.
Bioethics seeks to ensure that human moral values are not lost, regardless of the historical and social development of humanity, during attempts to resolve conflicts and / or ethical dilemmas.
Based on its four principles, it values the appropriate behaviors for each specific situation.
Some of the subjects that most require the intervention of bioethics are:
- Abortion;
- Cloning;
- Genetic engineering;
- Euthanasia;
- In vitro fertilization;
- Use of stem cells;
- Use of animals in experiments;
- Suicide.
It should be noted that the application of the principles of bioethics in relation to the above cases may vary depending on the country where it is practiced. What is sometimes allowed in certain countries can be classified as a crime in others. Abortion and euthanasia exemplify this situation.
