ICU患者下呼吸道感染鲍曼不动杆菌危险因素分析

摘要

目的：了解ICU患者下呼吸道感染鲍曼不动杆菌的危险因素。方法收集2013年1月至2015年12月我院ICU患者下呼吸道标本中检出的鲍曼不动杆菌菌株，分析下呼吸道感染鲍曼不动杆菌的危险因素。结果下呼吸道标本共分离鲍曼不动杆菌菌株169株，且均为该菌感染患者。下呼吸道感染鲍曼不动杆菌的危险因素包括慢性肺部疾病、机械通气时间、中心静脉置管、气管插管、低血清白蛋白。其中中心静脉置管、气管插管、低血清白蛋白是感染鲍曼不动杆菌的独立危险因素。结论重视ICU患者基础肺部疾病、规范ICU侵入性操作、改善ICU患者营养状况可能有利于减少下呼吸道感染鲍曼不动杆菌，减少医院感染的发生。%Objective To investigate the risk factors for nosocomial infection of Acinetobacter Baumannii ( A.B) in ICU. Methods This study collected data from respiratory specimens of patients in ICU of our hospital from 2013 to 2015.Risk factors of in-fection of A.B were analyzed.Results A total of 169 strains of A.B were isolated from ICU hospitalized patients.Central-venous catheter, chronic lung disease, artificial airway, lower serum albumin and time of mechanical ventilation were the risk factors for the A.B infection in lower respiratory tract.The independent risk factors for the occurrence of A.B.infection were the central-venous cath-eter, artificial airway and lower serum albumin level.Conclusion Reasonable treating the chronic lung diseases, keeping the specifi-cation of invasive operation and improving the nutritional status of patients in ICU may be beneficial to reduce the lower respiratory tract of A.B infection and the incidence of hospital related infection.
