The delay in the diagnosis of brain death represents a cause of deficiency of organs for transplant. In this prospective study we evaluate the role of Doppler sonography, to investigate typical velocimetric profiles of brain death, and to evaluate the delay between finding the typical profiles and diagnosis expressed according to law. In this ongoing study, we evaluated 32 patients affected from serious primitive intracranial diseases (Glasgow Coma Scale < or = 7). Of the 32 patients examined, 18 underwent or still remained in brain death. All the patients showed typical profiles, classified in 3 fundamental types. Start of monitoring, according to the current law, showed a delay from 12 to 27 hours. The authors conclude that Transcranial Doppler and Doppler c.w. represent an early and sensitive technique, rightly to include in the procedure of the diagnosis of brain death.
脑死亡诊断的延迟是移植器官短缺的一个原因。在这项前瞻性研究中，我们评估了多普勒超声的作用，以研究脑死亡的典型测速曲线，并评估发现典型曲线与依法诊断之间的延迟。在这项正在进行的研究中，我们评估了32例患有严重原发性颅内疾病（格拉斯哥昏迷量表≤7）的患者。在接受检查的32例患者中，18例已进入或仍处于脑死亡状态。所有患者均显示出典型曲线，分为3种基本类型。根据现行法律开始监测时，延迟时间为12至27小时。作者得出结论，经颅多普勒和连续波多普勒是一种早期且敏感的技术，应正确纳入脑死亡诊断程序。
