Three groups of patients were studied by echoencephalography using a one-dimensional encephalograph Eho 12. The first group consisted of 100 patients with a mild craniocerebral traumas. Good pulsations of the elements of the echoencephalogram were found during the study. The second group involved 14 people who had died as a result of craniocerebral trauma. The investigation performed postmortem revealed fixed echoencephalogram without any pulsations of its elements. The third group included 11 patients with severe craniocerebral trauma in a state of deep coma. These patients were on mechanical ventilation, their brainstem reflexes were absent, but the cardiac activity remained preserved. The echoencephalographic study in these patients showed a fixed screen curve, without pulsations of its elements. We conclude that absence of pulsations of the elements of echoencephalogram produced by one-dimensional echoencephalograph indicates brain death of the investigated patients. This investigation should be included as a component of the established diagnostic tests.
使用一维脑回波描记仪Eho 12对三组患者进行了脑回波描记术研究。第一组由100例轻度颅脑外伤患者组成。研究期间发现脑回波图各成分有良好的搏动。第二组包括14例因颅脑外伤死亡的患者。死后进行的检查显示脑回波图固定，其成分无任何搏动。第三组包括11例处于深度昏迷状态的重度颅脑外伤患者。这些患者接受机械通气，脑干反射消失，但心脏活动仍存在。对这些患者进行的脑回波描记术研究显示屏幕曲线固定，其成分无搏动。我们得出结论，一维脑回波描记仪产生的脑回波图成分无搏动表明被研究患者脑死亡。这项检查应作为既定诊断测试的一个组成部分。
