The effects of hypocalcaemia on somatosensory evoked potentials (SEPs) were studied in five patients after parathyroidectomy. Despite normal latencies the mean value of amplitudes of the SEPs in hypocalcaemic patients was greater than that in normocalcaemic subjects. Recovery functions of the SEPs showed a significant decrease in hypocalcaemic patients at interstimulus intervals of about 10 ms compared with those in normocalcaemic patients and in normal volunteers. Recovery functions appear to be a valid indicator of synaptic efficacy, especially for evaluation of the reduction in conduction efficacy of the central nervous system in hypocalcaemia.
对五名甲状旁腺切除术后患者的低钙血症对体感诱发电位（SEP）的影响进行了研究。尽管潜伏期正常，但低钙血症患者SEP波幅的平均值高于血钙正常的受试者。与血钙正常的患者和正常志愿者相比，低钙血症患者的SEP恢复功能在约10毫秒的刺激间隔时显著下降。恢复功能似乎是突触效能的有效指标，特别是用于评估低钙血症时中枢神经系统传导效能的降低。
