Auditory MLR and ABR were recorded simultaneously in 9 children under general anaesthesia, after electrocochleography had demonstrated a normal hearing threshold. In contrast to the ABR components which in all cases appeared to be clearly recognizable, and with latencies within the normal range, MLR revealed gross abnormalities represented by instability of the components and abnormal latency of the detectable peaks. Since such variations in the MLR pattern may be thought of as a direct consequence of general anaesthesia, it seems likely that these potentials reflect a neural activity which, in children, is affected by CNS drugs.
在9名接受全身麻醉的儿童中，在耳蜗电图显示听力阈值正常后，同时记录了听觉中潜伏期反应（MLR）和听性脑干反应（ABR）。与在所有情况下似乎都能清晰识别且潜伏期在正常范围内的ABR成分不同，MLR显示出明显异常，表现为成分不稳定和可检测峰值的潜伏期异常。由于MLR模式的这种变化可能被认为是全身麻醉的直接后果，这些电位似乎反映了一种神经活动，在儿童中，这种神经活动会受到中枢神经系统药物的影响。
