Clinical analysis of 105 cases of children febrile serzures.

目的 探讨小儿热性惊厥复发的危险因素。方法 对 10 5例热性惊厥患儿的临床资料进行回顾性分析。结果 10 5例患儿中复发 6 1例 (5 8.1% )。首发年龄 8个月～ 3岁 5 2例 (4 9.5 % ) ,初发体温 <39℃ 4 7例 (4 4 .8% ) ,有热性惊厥家族史者 4 5例 (4 2 .9% ) ,缺铁性贫血 35例 (33.3% ) ;低钠血症 39例中惊厥≥ 2次 2 4例 (6 1.5 % ) ,而血钠正常 31例中惊厥≥ 2次仅 3例 (9.7% ) (P <0 .0 1) ;6 0例患儿心肌酶谱有不同程度的升高。结论 ①首发年龄小、初发体温低、热性惊厥家族史阳性、缺铁性贫血及低钠血症均为复发的危险因素。②对于缺铁性贫血。

Objective To investigate the risk factors for children febrile serzures(FS)recurrence. Methods Clinical data of 105 FS cases were analyzed retrospectively. Results Among 105 cases, FS replased in 61 cases(58.1%) of whom the age at initial attack was 8 months-3 years in 52 cases(49.5%), the initial temperature was <39 ℃ in 47 cases(44.8%), 45 had family history of FS(42.9%) and iron-deficiency anemia occurred in 35 cases(33.3%). In 39 cases of hyponatremia there were 24 cases with at least two attacks of convulsion(61.5%) while in 31 cases of normal natrium there were 3 cases with at least two attacks of convulsion(9.7%)(P<0.01). Myocardial enzyme was found increased unevenly in 60 cases. Conclusion The lower initial age and temperature, positive family history of FS, iron-deficiency anemia and hyponatremia are all risk factors for convulsion recurrence in child with FS. Active treatment should be taken for the child patients with iron-deficiency anemia, hyponatremia and myocardial impairment.
