    AbstractWe performed transcranial Doppler (TCD) examinations on 54 comatose patients over a 1-year period. Of 49 patients with technically adequate TCD examinations, 23 met criteria for determination of brain death by clinical and EEG criteria (21) or clinical criteria alone (2; EEG not performed). A TCD waveform abnormality, consisting of absent or reversed diastolic flow, or small early systolic spikes, in at least 2 intracranial arteries, occurred in 21 brain-dead patients, but in none of the other patients in coma. With appropriate guidelines for performance and interpretation, TCD could be incorporated into institutional protocols as a rapid and convenient alternative to EEG for confirmation of brain death.
