Short latency somatosensory evoked potentials to median nerve stimulation (MN-SSEP) were studied in 292 normal children of 1 month to 14 years old and in 34 adults. We divided these normal children into 7 groups, each group containing about 40 children. Evoked potentials were recorded at 3 levels: Erb's point, seventh cervical vertebra, and contralateral parietal scalp. N 9, N 13 and N 20 wave forms were recorded in all the children, except that in some children under 2 months of age the N 20 component was absent on one side (7.3%). The mean latency of N 9 N 13 and N 20 decreased with age until they reached 1 year and 3-5 years of age respectively, and then it increased with age. The interpeak latency of N 13-N 20 decreased steadily with age, becoming close to the value of adults at about 8 years of age. There was no significant sex difference in interpeak latencies, but the difference was significant in absolute peak latencies. In this paper are proposed the normal referential values of MN-SSEP in children.
对292名1个月至14岁的正常儿童及34名成年人进行了正中神经刺激短潜伏期体感诱发电位（MN-SSEP）研究。我们将这些正常儿童分为7组，每组约40名儿童。在三个水平记录诱发电位：Erb点、第七颈椎和对侧顶叶头皮。所有儿童均记录到N9、N13和N20波形，但在一些2个月以下儿童中，一侧未出现N20成分（7.3%）。N9、N13和N20的平均潜伏期随年龄增长而缩短，直至分别达到1岁和3至5岁，然后又随年龄增长而延长。N13-N20的峰间潜伏期随年龄稳步缩短，约8岁时接近成年人的值。峰间潜伏期无显著性别差异，但绝对峰潜伏期差异显著。本文提出了儿童MN-SSEP的正常参考值。
