高热惊厥患儿血清钠浓度检测分析

Detection and Analysis of Serum Na+ Concentration for theChildren with Febrile Convulsions

目的：进一步了解阐明高热惊厥与血清钠浓度的关系。方法：用电解质分析仪对５５例高热惊厥和４０例高热无惊厥患儿进行电解质测定。结果：５５例高热惊厥组低血钠２５例（４５５％），４０例高热无惊厥组低血钠５例（１２５％），两组比较Ｐ＜００１。而低血钠２５例中惊厥≥２次者占５６％（１４／２５），血钠正常３０例中惊厥≥２次者占６７％（２／３０），且惊厥≥２次患儿平均血钠浓度明显低于惊厥１次的患儿。结论：提示高热惊厥患儿血清钠浓度明显降低，并随血钠浓度的降低，惊厥再发概率增大。

Objective:To investigate the relationship between the children with febrile convulsions and their serum Na+ concentration. Methods:The serum Na+ concentration of 55 cases of febrile convulsion and 40 cases of febrile without convulsion by the electrolytic analyzer. Results:The incidence(45 15%)of low natremia in febrile convulsion group is higher than that (12 15%)in febrile without convulsion group (P<0 01).The incidence(56%) of two or more convulsions in 25 cases with low natrenia is higher than that(6 17%) in 30 cases with normal serum Na+ concentration.Average serum Na+ concentration in the patients with two or more febrile convulsions is lower than that in the patients with one febrile convulsion. Conclusions: The study suggests that serum Na+ concentrations of children with febrile convulsion are low. The recidivating rate of febrile convulsion increases with descending serum Na+ concentration.
