[Palliative medicine from deontology].

Palliative medicine is the medicine that accompanies the person in their process of dying for alleviate their unwanted suffering, is a medicine that offers comfort care to the patient and his family, a medicine that does not prolong life unnecessarily at the expense of suffering, but rather it widens it, it is a medicine that takes care of life. Medical deontology tells us how our good medical practice through the rules contained in the Code of Ethics. In this article I address the practice of palliative medicine taking into account medical deontology, focusing on two issues that generate controversy such as palliative sedation and euthanasia. I consider that the good practice of palliative medicine consists, not in intentionally causing the death of the patient, but neither in unnecessarily prolong his agony, but to alleviate his suffering until death comes.
