高龄患者医院获得性肺炎的临床调查及预防对策

Clinical investigation of iatrogenic pneumonia in senile patients and its preventive measure

目的 :了解高龄患者医院获得性肺炎的临床特点 ,病原菌分布情况及探讨预防措施。方法 :对 85例高龄医院内获得性肺炎患者进行回顾性分析。结果 :最常见的基础病依次为脑血管意外 ( 35 2 % ) ,恶性肿瘤 ( 2 9 4% ) ,腹部外科手术后 ( 14 1% ) ,诱发因素多为长期卧床不能活动 ,长期使用激素 ,气管插管及气管切开 ,使用抗生素不合理。主要病原菌为G-杆菌 ,其中以铜绿假单胞菌及大肠埃希氏菌为主 ,其次为真菌感染。结论 :高龄患者抵抗力低下 ,基础病多 ,不合理使用抗生素 ,是造成医院感染和影响预后的主要因素。

Objective:To understand clinical feature of iatrogenic pneumonia in senile patients,pathogenic bacteria distribution condition,and its preventive measureMethod:Undergo retrospective analysis about 85 cases senile patients with iatrogenic pneumoniaResult:The common foundamental diseases are cerebral vascular accident(352%),maligant tumor(294%),abdomenal operation(141%) the inducing factor include long time in bed,continue accepting corticosteroid,trachea intubation and trachea incision,unreasonable application of antibioticsThe main pathogen are bacillus G-,then aeruginosin and Esch^erichia coli,fungi infectionCo^nclusion:The senile patients with immuno resistance,many foundamental disease,unreasonable application of antibiotics are main factor of iatrogenic infection and its progrosis,we should mainforce disinfection managment and take necessary preventive measure
