Oscillating flow or systolic spikes are typical Doppler-sonographic flow signals found in the presence of cerebral circulatory arrest, which if irreversible, results in brain death. The Neurosonology Research Group (NSRG) of the World Federation of Neurology (WFN) created a Task Force Group in order to evaluate the role of Doppler-sonography as a confirmatory test for determining brain death.
The available evidence from the literature has been reviewed and discussed by a group of experts, the members of the Task Force Group on cerebral death of the NSRG.
Extra- and intracranial Doppler-sonography is a useful confirmatory test to establish irreversibility of cerebral circulatory arrest as optional part of a brain death protocol. Doppler-sonography is of special value when the therapeutic use of sedative drugs renders electroencephalography unreliable. Doppler-sonographic criteria are defined and guidelines for the use of Doppler-sonography in this setting are presented.
振荡血流或收缩期峰值是在脑循环停止时发现的典型多普勒超声血流信号，若脑循环停止不可逆，则会导致脑死亡。世界神经病学联合会（WFN）的神经超声研究小组（NSRG）成立了一个特别工作组，以评估多普勒超声作为确定脑死亡的确认性检查的作用。
文献中的现有证据已由一组专家进行了审查和讨论，这些专家是NSRG脑死亡特别工作组的成员。
颅外和颅内多普勒超声是一种有用的确认性检查，可作为脑死亡判定流程的可选部分，用于确定脑循环停止的不可逆性。当使用镇静药物使脑电图检查不可靠时，多普勒超声具有特殊价值。本文定义了多普勒超声标准，并给出了在这种情况下使用多普勒超声的指南。
