小儿烧伤后无热惊厥原因分析

目的：探讨小儿烧伤后无热惊厥原因。方法：回顾性分析我院1990年1月～2000年12月23例住院期间发生惊厥的临床资料。结果：23例中14例为无热惊厥，约占60％，多合并有水电解质紊乱，其中低钠血症8例．代谢性酸中毒6例，低血钾4例，低血钙3例，低镁血症2例。低血糖和癔病性抽搐各1例。结论：水电解质代谢紊乱在小儿烧伤中较为常见，且为小儿烧伤无热惊厥的重要原因，其中低钠血症最为常见，而且发生代谢性酸中毒的同时存在潜在性的低血钾和低血钙，低镁血症亦不容忽视，并且要注意数种电解质紊乱并存及其他非感染性脑损伤和中枢神经功能异常亦可导致惊厥。

Analysis of Reasons Accounting for Non-fever Convulsion in Pediatric Burns

Objective: To investigate causes of non-fever convulsion in pediatric burn injuries.Methods: 23 cases with convulsion during hospitalization from Jan.1990 to dec.2000 were retrospectively reviewed.Results:Of the 23 cases, 14 cases(60%) were non-fever convulsion. Most cases accompanied by disorders in fluid and electrolyte balance. 8 of 14 cases with hyponatremia, 6 cases with metaboic acidosis , 4 cases with hypokalemia, 3 cases with hypocalcemia. 2 cases with hypomagnesemia.Conclusion:Fluid and electrolyte diorders are common in pediatric burns, and are main causes of pediatric non-fever convulsion. Of which hyponatremia is the most common, metaboic acidosis, hypokalemia, hypocalcemia, and hypomagnesemia occupied the rest. Mixed fluid and electrolyte diorders should be emphsized while non-infectious brain injuries and centrical nervous disorders may not be neglected.
