危重患儿神经系统异常回顾分析

目的 了解神经系统异常在儿科危重2患儿中的发病情况及其预后的关系。方法 对PICU113例危重患儿神经系统异常的病因、预后及临床表现特点进行回顾性分析。结果 神经系统异常发生率54%，其中原发病为神经系统疾病者占63.8%，非神经系统疾病发生神经系统合并症者占36.1%；有神经系统异常者病死率（36.1%)明显高于无神经系统异常者（5.8%)，而原发病为神经系统疾病患儿病死率（33.0%)与非神经系统疾病发生神经合并症者患儿病死率（40.9%)比较，差异无显著性。结论 神经系统异常是影响儿科危重病预后的一个重要因素。

Retrospective analysis on abnormalities in the nervous system in children withcritical diseases

Objective To study the incidence of nervous system abnormalities in children with critical diseases and its relationship to the prognosis.Method Etiology, prognosis and clinical characteristics of nervous system abnormalities was retrospectively analyzed in 113 patients with critical diseases in PICU.Results The incidence of nervous systemic abnormalities was 54 %. 63.8 % of these patients suffering from diseases that primarily occured in nervous system, while 36.1 % of whom had only complications but no primary diseases in nervous system. The mortality of cases with nervous systemic abnormalities was 36.1 % ,which was significantly higher than that of cases without nervous systemic abnormalities (only 5.8 %). The mortality between patients with primary nervous diseases (33 %) and patients with only nervous systemic complications (40.9 %) had no significant difference. Conclusion Abnormalities of nervous system was an important factor affecting the prognosis of pediatric patients with critical diseases.
