脑病科病房医院感染分析

Analysis on Nosocomial Infections in Encephalopathy Wards

目的:探讨我院脑病科发生医院感染的高发部位、病原菌特点、危险因素情况,为预防和控制医院感染提供思路。方法:对2016年7月—2017年6月我院脑病科1 131例住院患者在前瞻性监测的同时进行回顾性调查分析。结果:68例医院感染,阳性结果检出均为下呼吸道感染;医院感染的病原菌主要为革兰阴性杆菌,占66.67%;分离的革兰阳性球菌对替考拉宁、万古霉素高度敏感;革兰阴性杆菌对美罗培南、左氧氟沙星最敏感;真菌对测试的抗真菌药物均敏感。结论:脑病科住院患者医院感染以呼吸道常见,依据药敏结果,革兰阳性菌耐药率最高,而革兰阴性菌对多数常用抗菌药物敏感,真菌对所有测试的抗真菌药物均高度敏感。

Objective:To explore the sites of high incidence,characteristics of pathogens and risk factors of nosocomial infections in the Encephalopathy Department of our hospital to provide ideas for preventing and controlling nosocomial infections.Methods:A retrospective survey was conducted on 1131 inpatients in the Encephalopathy Department from July 2016 to June 2017 in the hospital.Results:In 68 cases of hospital infections,their positive results showed lower respiratory tract infections.The pathogens of the nosocomial infections are mainly Gram-negative bacilli,accounting for 66.67%.Isolated Gram-positive cocci are highly sensitive to teicoplanin and vancomycin.Gram-negative bacilli are sensitive to meropenem and levofloxacin.Fungi are sensitive to the tested antifungal drugs.Conclusion:Nosocomial infections in inpatients in the Encephalopathy Department are common in respiratory tracts.According to the results of drug sensitivity,the drug resistance rate of Gram-positive bacteria is the highest,while Gram-negative bacteria are sensitive to most commonly used antimicrobials,and fungi are highly sensitive to all tested antifungal drugs.
