摘要

本回顾性研究包括34例因严重缺氧引起的脑损伤死亡的患者,这些患者在同一天通过脑电图和AEP或SEP进行评估,这些电生理方法中至少有一种显示死亡预后。脑电图结果确定了76%的患者有致命结果,而SEP可靠地预测了93%的患者死于脑缺氧的结果。在一些患者中,中枢作用药物使基于脑电图而不是基于sep的预后不可能。然而,在一些致死性脑损伤的病例中,只有脑电图结果而不是脑电图结果可以预测致死性结果。因此,脑电图和SEP联合评估是早期预后的最佳评估方法。BAEP的预后价值低于EEG。BAEP结果表明,致命的结果主要出现在脑干功能丧失的最后临床阶段,而脑电图和SEP确定了相当数量的致命病例,尽管临床结果相对有利。缺氧事件发生后3天内进行的早期电生理测试的评估结果对脑电图与BAEP或sep结果的预后意义分别有相同的估计。

[The prognostic place of EEG in comparison with evoked potentials in severe hypoxic brain damage].

This retrospective study comprises 34 patients, who died due to the cerebral damage caused by severe anoxia, who were assessed by EEG and AEP or SEP on the same day and in whom at least one of these electrophysiological methods indicated a fatal prognosis. EEG-findings identified 76% of patients with fatal outcome, whereas SEP reliably predicted the outcome in 93% of patients, who died of the cerebral anoxia. In some patients centrally acting drugs made EEG-based but not SEP-based prognosis impossible. In some cases of fatal brain damage, however, only the EEG-findings as opposed to SEP-findings predicted the fatal outcome. Thus the combined assessment by EEG and SEP appears to be optimal in the assessment of an early prognosis. The BAEP were of less prognostic value than the EEG. BAEP findings indicating a fatal outcome were to be found mainly in final clinical stages with loss of brainstem function, whereas EEG as well as SEP identified a considerable number of fatal cases in spite of comparably favourable clinical findings. The evaluation of early electrophysiological testing done within the first 3 days after the anoxic event results in an identical estimation of the prognostic significance of EEG versus BAEP- or SEP-findings, respectively.
