“…Its diagnosis is based on an exhaustive neurological examination [1][2][3][4][5][6], which should be conducted by physicians with experience in managing neurocritical patients. Declaring a patient brain dead has tremendous medical, ethical, and legal implications since it is on this determination that high-responsibility decisions are based, such as discontinuing support measures or the procurement of organs for transplant.…”

The clinical death of a person is the death of the brain. There is a fairly general consensus in western medicine on the necessary criteria and the mode of proceeding for a correct diagnosis of "brain death". In a specific case, with a reasonable previous record of catastrophic brain damage and certain neurological exploratory signs, an expert practitioner is able to diagnose clinical death. Accepting that the diagnosis of death is an exercise of diagnostic judgement, in practical application, which cannot as such provide absolute certainty; we have to accept that, in spite of this uncertainty, we have to take sensible and prudent decisions. However, there are dissenting opinions that believe in the need for a higher degree of certainty before taking decisions It is necessary to try to understand the concept of "brain death" in order to be able to take responsible decisions. This concept is a real "cultural construction", in which it is necessary to have knowledge about the scientific definition of death, how death can be diagnosed in practice, when it is possible to say that someone is clinically dead, and what is the degree of evidence carried by the diagnosis.

Transcranial Doppler evaluates cerebral hemodynamics in patients with brain injury and is a useful technical tool in diagnosing cerebral circulatory arrest, usually present in the brain-dead patient. This Latin American Consensus was formed by a group of 26 physicians experienced in the use of transcranial Doppler in the context of brain death. The purpose of this agreement was to make recommendations regarding the indications, technique, and interpretation of the study of transcranial ultrasonography in patients with a clinical diagnosis of brain death or in the patient whose clinical diagnosis presents difficulties; a working group was formed to enable further knowledge and to strengthen ties between Latin American physicians working on the same topic.A review of the literature, concepts, and experiences were exchanged in two meetings and via the Internet. Questions about pathophysiology, equipment, techniques, findings, common problems, and the interpretation of transcranial Doppler in the context of brain death were answered. The basic consensus statements are the following: cerebral circulatory arrest is the final stage in the evolution of progressive intracranial hypertension, which is visualized with transcranial Doppler as a "pattern of cerebral circulatory arrest". The following are accepted as the standard of cerebral circulatory arrest: reverberant pattern, systolic spikes, and absence of previously demonstrated flow. Ultrasonography should be used - in acceptable hemodynamic conditions - in the anterior circulation bilaterally (middle cerebral artery) and in the posterior (basilar artery) territory. If no ultrasonographic images are found in any or all of these vessels, their proximal arteries are acceptable to be studied to look for a a pattern of cerebral circulatory arrest.
