The prognosis after traumatic coma is often unclear. We investigated the prognostic value of somatosensory (SSEP) and early acoustic (EAEP) evoked potentials on comatose patients in the intensive care unit regarding long-term outcome. Different evaluation systems were investigated.
This was a retrospective analysis of 100 patients. SSEP and EAEP were examined at different times and analysed according to the Riffel score. Combinations of the different types of potentials were evaluated regarding possible improvement of outcome prediction.
The positive predictive value of at least one missing peak V of the EAEP regarding a fatal prognosis was 83%. The negative predictive value of the EAEP was 96%. A good outcome (GOS 4+5) could be predicted by bilateral normal SSEP and EAEP with a positive predictive value of 98%.
Early evaluation of SSEP and EAEP allows reliable prognostic predictions regarding a later outcome in patients with severe traumatic brain injury and should therefore be used more often for intensive care patients.
创伤性昏迷后的预后往往不明确。我们研究了体感诱发电位（SSEP）和早期听觉诱发电位（EAEP）对重症监护病房昏迷患者长期预后的预测价值。对不同的评估系统进行了研究。
这是一项对100例患者的回顾性分析。在不同时间检查SSEP和EAEP，并根据里费尔评分进行分析。评估不同类型电位的组合对改善预后预测的可能性。
EAEP至少一个V波峰缺失对致命预后的阳性预测值为83%。EAEP的阴性预测值为96%。双侧SSEP和EAEP正常可预测良好预后（GOS 4+5），阳性预测值为98%。
对SSEP和EAEP的早期评估能够对重度创伤性脑损伤患者的后期预后做出可靠的预测，因此应更频繁地用于重症监护患者。
