外科重症监护病房医院肺部感染的病原菌分布

Pathogen Distribution of Nosocomial Pulmonary Infection in Surgical Intensive Care Unit

目的 研究外科重症监护病房 (SICU)医院获得性肺部感染的病原菌分布。方法 选取我院SICU病房10 2例住院时间 >48h的连续患者为研究对象 ,每日常规进行血常规检查 ,并分别于入院第 3天、第 5天、第 7天取下呼吸道分泌物进行培养及药物敏感实验 ,并进行胸部X线检查 ,采集院内获得性肺炎的病原资料。结果 SICU院内获得性肺炎的发病率为 41.4%,其中 ,革兰阴性菌 76 .8%,革兰阳性菌 9.1%;革兰阴性杆菌中 ,铜绿假单胞菌占 35 .4%,不动杆菌占 13 .2 %。结论 我院SICU院内获得性肺部感染的主要病原菌是铜绿假单胞菌和不动杆菌。

OBJECTIVE To study the main pathogens of nosocomial pulmonary infection in SICU. METHODS Prospective studies were conducted in 102 cases of SICU patients with ICU LOS (lengths of stay) no less than 48 hours.Bacterial culture and antibiotic sensitivity test were used for pathogen examination. RESULTS Among 102 cases,the rate of pulmonary infection was 41.2%,the main pathogens were Gram negative organisms(86.4%), the number of Gram positive organisms was 13.6%. CONCLUSIONS The results suggest that except the extent of severe disease,the main pathogen of noscomial pulmonary infection in our SICU be Pseudomonas aeruginosa and Acinetobacter baumannii.
