摘　　要：目的探讨儿童血管迷走性晕厥（VVS）基础状态下血清电解质浓度的变化。方法2004—06—2007—04在中南大学湘雅二医院儿童晕厥专科门诊就诊或住院的不明原因晕厥或晕厥先兆儿童79例（晕厥组），男31例，女48例，平均年龄（11．18±2．47）岁。匹配健康儿童11例为对照（对照组），男5例，女6例，平均年龄（9．59±2．47）岁。用日本HITACHI公司7600—020全自动生化分析仪检测儿童VVS基础状态下血清电解质（钠、钾、氯、钙、磷、镁）的浓度。结果VVS基础状态下晕厥组较对照组血清钾降低、血清钙增加（P〈0．05），血清钠降低不明显（P〉0．05）。血清电解质浓度在直立倾斜试验（HUTT）反应结果及晕厥频次之间比较差异均无统计学意义（P〉0．05）。结论血清电解质浓度的变化可能参与VVS发病，临床诊治VVS时应重视血清电解质浓度的变化。Objective To explore the change of serum electrolyte concentrations in the children with vasovagal syncope （ VVS ） at baseline. Methods 79 children with unexplained syncope and prodromata [ 31 male, 48 female, mean （ 11.18± 2.47 ） years old ] were included in the study and 11 healthy children [ 5 male, 6 female, mean （9.59 ± 2.47 ） years old ] were matched as controls. Serum electrolyte concentrations （ sodium, potassium, chlorine, calcium, phosphonium, magnesium） were detected by HITACHI 7600 -020 automatic biochemistry analyzer at baseline. Results Compared with control group, serum potassium was significantly lower and serum calcium higher in syncope group （ P 〈 0.05 ） , serum sodium slightly decreased （ P 〉 0. 05 ）. There was no significant difference in serum electrolyte concentrations between HUTT response result and syncope frequency （ P 〉 0.05 ）. Conclusion The changes of serum electrolyte concentrations may play a role in the pathophysiology of VVS, so it is important to think highly of the change of serum electrolyte concentrations during diagnosis and treatment of VVS.
