380例森林脑炎临床分析

Clinical analysis on 380 cases of forest encephalitis

目的 研究森林脑炎的临床特点以指导临床分型及诊治 ,并为制定职业性森林脑炎的诊断标准提供理论依据。方法 回顾性调查分析了 3 80例森林脑炎病例 ,研究病人的发病年龄、潜伏期、主要症状和体征及实验室检查。结果 临床分析显示 :(1)潜伏期与病情严重程度有关 ,病情越轻潜伏期越长 ,病情越重潜伏期越短 ;(2 )平均住院时间轻型的病人比重型的病人明显缩短 ;(3 ) 3 80例中 ,检测特异性IgG 2 3 0人 ,特异性IgM 72人 ,其滴度均有不同程度升高 ,具有可靠诊断价值。结论 森林脑炎临床宜分为 3型 ,即顿挫型、轻型和重型较为符合临床实际 。

Objective To study the clinical features of forest encephalitis for guiding its typing,diagnosis and therapy,so that to afford the theoretical basis for formulating the diagnostic criterion of occupational forest encephalitis.Methods Through retrospectively analysis on 380 cases of forest encephalitis,the patient's age,latent period,the main symptoms and signs,laboratory tests were carefully studied.Results The clinical analyses were made on the basis of traditional typing method,it showed(1)The latent period is related to the severity of disease,it seems that the longer the latent period was,the more mild the severity showed.(2)The mean length of stay in hospital in mild type was much shorter than that of severe one.(3)In 380 cases,230 patient's serum specific IgG and 72 patient's serum specific IgM were tested.All of those antibodies were raised.Conclusion It seems more practical and convenient that forest encephalitis might be classified into three types clinically,namely mild type,middle type and severe type.
