Determination of brain death with use of color duplex scanning in the intensive care unit setting.
OBJECTIVE
To determine if color flow duplex scanning (CFDS) can be used for rapid confirmation of presumed brain death.


METHODS
Pilot cohort study comparison of CFDS with radionuclide cerebral scanning (RCS) as the criterion standard.


METHODS
Community-based level I trauma center intensive care unit.


METHODS
Twenty-four patients who satisfied criteria for presumed brain death.


METHODS
Confirmation of presumed brain death.


RESULTS
CFDS correctly identified 16 of 24 patients as brain dead, confirmed by RCS. Eight patients with brain flow on RCS were also correctly identified by CFDS. Only two of 24 patients survived their severe injuries.


CONCLUSIONS
CFDS provides a uniform, cost-effective diagnostic tool for rapid confirmation of clinical brain death with 100% accuracy. Its use should complement RCS, given its rapid interpretation, portability, and economical assessment of presumed brain death.
