The diagnosis of brain death remains a clinical challenge for intensive care unit physicians.
Worldwide regulations in its diagnosis may differ, and the need of ancillary tests after a …

Abstract Introduction Transcranial Doppler (TCD) can detect the cerebral circulation arrest
(CCA) in brain death. TCD is highly specific, but less sensitive because of false-negatives …

Objective Barbiturate therapy or hypothermia precludes proper diagnosis of brain death
either clinically or by EEG. Specific intracranial flow patterns indicating cerebral circulatory …

Abstract Background Transcranial Doppler (TCD) ultrasonography to demonstrate cerebral
circulatory arrest (CCA) is a confirmatory test for brain death (BD). The primary aim of this …

Transcranial Doppler ultrasound is able to demonstrate cerebral circulatory arrest
associated to brain death, being especially useful in sedated patients, or in those in which …

Transcranial Doppler (TCD) is a repeatable, at‐the‐bedside, helpful tool for confirming
cerebral circulatory arrest (CCA). Despite its variable accuracy, TCD is increasingly used …

Introduction: The clinical criteria for brain death consist of the demonstration of the absence
of any clinical sign of encephalic activity. Confirmatory testing is usually not required for the …

Objective: To determine the clinical validity of transcranial Doppler ultrasonographic (TCD)
signs of total cerebral circulatory arrest for confirmation of brain death and to define the test …

Ziel: Die transkranielle Dopplersonografie (TCD) kann in der Hirntoddiagnostik als
apparative Zusatzuntersuchung angewendet werden. Ziel der Studie war die Darstellung …

Ancillary tests can be used for the diagnosis of brain death in cases wherein uncertainty
exists regarding the neurological examination and apnoea test cannot be performed …
