儿童致死性病毒性脑病7例

目的探讨致死性病毒性脑病的临床和实验检查特点。方法回顾性分析7例致死性病毒性脑病患儿临床过程及预后,肝酶学、脑脊液常规改变,头颅CT改变。结果7例患儿均呈骤然高热、严重抽搐和迅速进入昏迷、肝酶显著升高。4例死亡,3例留有严重神经系统后遗症;血氨均正常;头颅CT均显示显著脑肿胀,可见对称性基底核低密度病变。结论高热、迅速发生抽搐和昏迷、肝功能损害的患儿,应警惕致死性病毒性脑病发生。

Clinical Analysis of 7 Children with Fatal Virus Encephalopathy

Objective To explore clinic manifestations and laboratory investgation of virus encephalopathy.Methods The clinical course,cerebrospinal fluid(CSF),hepatic dysfunction,computerized tomography of 7 cases treated in our hospital from October 1999 to March 2005 were retrospectively reviewed.Results Seven cases of virus encephalopathy were typically associated with a suddent onset of high fever,severe convulsion,rapidly progressive coma,marked elevations of alanine aminotransferase(AST) and aspartate transaminase(ALT).Four cases died,3 cases had severe sequelae.Blood ammonemia was normal,brain CT scans revealed peripheral or basal nuclei low-density areas.Conclusion Children with a sudden onset of high fever,severe convulsions,rapidly progressive coma may have a poor prognosis.
