抽象的。目的：用早期体感诱发电位和声诱发电位预测重型颅脑损伤后昏迷患者的远期预后尚有争议。我们的目的是检查诱发电位的不同单一成分在昏迷患者中的预测能力。方法：检测N20波的波幅和潜伏期、左右半球波幅差、中枢传导时间(CCT)、N20左右波幅比、V峰波幅和潜伏期、峰间潜伏期Tv和V/I波幅比，并于出院3年后对患者的远期临床结果进行再评估，并与不同成分进行相关性分析。结果：只有中枢传导时间和N20波潜伏期与预后有统计学意义(p=0.0366)。EAEP的V/I波幅比值在不同预后组之间无显著统计学差异。结论：在本研究中，使用SSEP和EAEP的单一成分本身并不能预测脑外伤后的长期临床结果。为了实现这一目标，里菲尔分数等综合系统是必要的。
ABSTRACT. Purpose: The prediction of the long-term outcome of comatose patients after severe traumatic brain injury (TBI) using early somatosensory and acoustic evoked potentials is controversial. It was our aim to examine the different single components of the evoked potentials regarding their predictive capacity in comatose patients. Methods: We examined the amplitude and latency of the wave N20, the amplitude differences between right and left hemisphere, the central conduction time (CCT), the amplitude ratio N20 left/N20 right, the amplitude and latency of peak V, the inter-peak latency TV and the amplitude ratio V/I. The long-term clinical outcome of the patients was re-evaluated 3 years after their discharge and correlated with the different components. Results: Only the central conduction time (CCT) and the latency of the wave N20 indicated a statistical correlation with the later outcome (p = 0.0366). The amplitude ratio of wave V/I of the EAEP did not reveal a significant statistical difference between the various outcome groups. Conclusions: In this study, the use of single components of the SSEP and EAEP per se could not predict the long-term clinical outcome after TBI. Combined systems such as the Riffel Score are necessary in order to achieve this goal.
