Short latency auditory nerve and brainstem evoked responses (BAERs) and long latency cortical auditory evoked responses (CAERs) in 75 long-term traumatic brain injury (TBI) cases were compared. CAERs were found to be significantly correlated with clinical disability as measured by the Disability Rating Scale, while BAERs were not. Also, BAER patterns were consistently and significantly less abnormal and less sensitive to overall dysfunction than CAER patterns. Findings support previous observations that BAERs have relatively little utility for evaluating in surviving TBI patients the degree of overall brain impairment. In general, long latency AEP patterns are better able to reflect the extent and severity of brain dysfunction and overall clinical condition than are short latency AEP patterns in long-term severe TBI patients, and these patterns should be obtained routinely in the evaluation of such patients.
对75例长期创伤性脑损伤(TBI)患者的短潜伏期听觉神经和脑干诱发反应(BAERs)以及长潜伏期皮层听觉诱发反应(CAERs)进行了比较。结果发现,CAERs与通过残疾评定量表测量的临床残疾显著相关,而BAERs则不然。此外,与CAER模式相比,BAER模式始终明显不那么异常,对整体功能障碍的敏感性也较低。这些发现支持了先前的观察结果,即BAERs在评估存活的TBI患者的整体脑损伤程度方面作用相对较小。一般来说,在长期重度TBI患者中,长潜伏期听觉诱发电位模式比短潜伏期听觉诱发电位模式更能反映脑功能障碍的程度和严重程度以及整体临床状况,在评估此类患者时应常规获取这些模式。
