In a prospective study of 69 children with febrile convulsions, serum sodium levels were often lower than normal (52% had levels < 135 mmol/l). The mean level (134.4 +/- 0.4 mmol/l) was significantly lower as compared to a group of children without fever (140.6 +/- 0.4 mmol/l, n = 23) and as compared to a group with fever but without convulsions (137.6 +/- 0.6 mmol/l, n = 31). The probability of a repeat convulsion within the same febrile period appeared to be significantly related to the serum sodium level.
Measurement of the serum sodium is a valuable investigation in the child with a febrile convulsion. The lower the serum sodium level, the higher the probability of a repeat convulsion. This knowledge may be of practical value in deciding whether to admit the child or allow it to return home and in advising parents or carers of the risk of a repeat convulsion.
在一项对69名热性惊厥儿童的前瞻性研究中，血清钠水平常低于正常（52%的儿童血清钠水平<135 mmol/L）。与一组无发热儿童（140.6±0.4 mmol/L，n = 23）以及一组有发热但无惊厥儿童（137.6±0.6 mmol/L，n = 31）相比，平均水平（134.4±0.4 mmol/L）显著更低。在同一发热期内再次惊厥的可能性似乎与血清钠水平显著相关。
对于热性惊厥儿童，测定血清钠是一项有价值的检查。血清钠水平越低，再次惊厥的可能性越高。这一知识在决定是否收治儿童或允许其回家以及向家长或照料者告知再次惊厥风险方面可能具有实际价值。
