OBJECTIVE
To determine if color flow duplex scanning (CFDS) can be used for rapid confirmation of presumed brain death.
DESIGN
Pilot cohort study comparison of CFDS with radionuclide cerebral scanning (RCS) as the criterion standard.
SETTING
Community-based level I trauma center intensive care unit.
PATIENTS
Twenty-four patients who satisfied criteria for presumed brain death.
MAIN OUTCOME MEASURE
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.
目的
确定彩色血流双功扫描（CFDS）是否可用于快速确认疑似脑死亡。
设计
以放射性核素脑扫描（RCS）作为标准对照，对CFDS进行的前瞻性队列研究。
地点
社区一级创伤中心重症监护病房。
患者
24例符合疑似脑死亡标准的患者。
主要观察指标
确认疑似脑死亡。
结果
CFDS正确识别出24例患者中的16例为脑死亡，经RCS证实。RCS显示有脑血流的8例患者也被CFDS正确识别。24例患者中只有2例在重伤后存活。
结论
CFDS为快速确认临床脑死亡提供了一种统一、经济有效的诊断工具，准确率达100%。鉴于其对疑似脑死亡的快速解读、便携性和经济评估，其应用应作为RCS的补充。
