[Acute respiratory distress syndrome. Role of steroids].

The acute respiratory distress syndrome (ARDS) represents 7.7% of the intensive care population, and is associated with great morbidity and mortality (58%). Frequently, the mortality can be attributed to more than one cause. Refractory hypoxemia is uncommon (15%) and most of the patients also have multiple organic dysfunction, sepsis or septic shock. Although there are many publications concerning series of cases and clinical trials using steroids as a part of the treatment of ARDS, this issue remains controversial. In this article the role of steroids in the ARDS is evaluated by analysis of the available literature. We conclude that steroids are useful in a subgroup of patients with unresolving ARDS, after ruling out an active infection or after treatment with antibiotics.

[Euthanasia].

Technological progress in medicine regarding the application of life-sustaining treatment in the critical patient and the cultural changes that have taken place in contemporary society with respect to the patients' right to decide over the end of their lives, demand the existence of a definition of euthanasia that will acknowledge this new scenario. The concept of euthanasia would be very specifically limited by the exclusion of so-called passive forms of euthanasia and of omission as a possible procedure to cause death and the need for the explicit request of the patient involved. Likewise, the definition of euthanasia should include a specific reference to the means through which death is to be achieved. Euthanasia would thus be defined basically as causing the death of a patient suffering from a mortal disease, upon his or her request and for his or her own benefit, by administering a toxic or poisonous substance in mortal doses. This restrictive definition would differentiate euthanasia from cases of refusal to receive treatment, even if death is the consequence of such refusal, and also from cases in which life-sustaining treatment is withheld or withdrawn to enable the occurrence of death.

[Intervened death: from brain death to withholding or withdrawal of life-sustaining treatment].

The concept of intervened death accounts for all those situations in which the withholding or withdrawal of life-sustaining treatment constitutes a limit to therapeutic action associated to the occurrence of the traditional cardio-respiratory death. The 1968 Harvard Report advanced a new definition of death through the concept of complete cessation of global brain functions and, more than thirty years later, this process of intervention in its diagnosis may be seen as a continuum link to the need to procure organs for transplant purposes and the need to avoid long agonies in unrecoverable patients. During the last decade, the ethical admissibility of withdrawing ordinary and advanced life-sustaining therapy in cases that do not amount to brain death diagnosis--such as vegetative states and other irreversible clinical situations--and even the advances made for purposes of obtaining organs for transplant purposes in these situations (with the explicit authorization of the donor or his/her representative) allows a joint interpretation of these situations through the acceptance that limits may be established in medical assistance. Reflection on intervened death as an emerging phenomenon of our culture is mandatory so that society may get involved in an issue of its absolute and exclusive interest.
