摘要
[目的]分析重症监护病房(ICU)呼吸机相关肺炎(VAP)与医院获得性肺炎(HAP)病原学特征,为临床经验性选择抗菌药物提供依据。[方法]回顾性分析2006年1月~2007年12月入住ICU患者VAP和HAP发生情况,并对临床痰标本分离出的病原菌及其耐药性进行分析。[结果]使用呼吸机的223例患者发生VAP106例次,感染发生率47.5%;未使用呼吸机的538例患者发生HAP124例,感染发生率23.0%。使用呼吸机患者痰标本分离出的173株病原菌占前5位的依次为:铜绿假单胞菌(36.4%),白色念珠菌(13.9%)、鲍曼/溶血不动杆菌(11.6%)、光滑念珠菌(8.7%)、克雷伯菌属(8.1%);未使用呼吸机患者痰标本分离出的181株病原菌占前5位的依次为:铜绿假单胞菌(22.6%),大肠埃希菌(14.9%),金黄色葡萄球菌(12.2%),克雷伯菌属(11.1%),白色念珠菌(9.4%)。[结论]使用呼吸机患者肺部感染发生率高;VAP患者分离出的病原菌非发酵菌比例高于HAP,而HAP患者分离出的病原菌中肠杆菌科细菌和革兰阳性球菌比例高于VAP。应加强ICU感染病原菌及其耐药性监测,采取综合控制措施预防和治疗VAP和HAP。
[Objective] To analyze the characteristics of pathogens and bacterial susceptibility in the patients with VAP and HAP in ICU,so as to provide basis for choosing the antibiotics in the clinical experience. [Methods] The retrospectively analyzed the incidence of VAP and HAP on patients in ICU from 2006 to 2007. Pathogens distribution and their drug resistance were also analyzed. [Results] 106 /223(47.5%) VAP cases were diagnosed,while 124 /538(23.0%) HAP cases who did not receive the mechanical ventilation were diagnosed. The top five pathogenic bacteria in ventilated patients were Pseudomonas aeruginosa(36.4%) ,Candida albicans(13.9%) ,Acinetobacter baumannii(11.6%) ,Candida glabrata(8.7%) and Klebsiella( 8.1% ) ;The top five pathogenic bacteria in non-ventilated patients were Pseudomonas aeruginosa( 22.6% ) ,Escherichia.coli(14.9%) ,Staphylococcus aureus(12.2%) ,Klebsiella(11.1%) and Candida albicans(9.4%) . [Conclusion] The incidence of pneumonia in ventilated patients was high,and the proportion of non-zymophyte species in ventilated patients was higher than ones in non-ventilated patients,while Enterobacteriaceae and gram-positive cocci species in non ventilated patients was higher than those in non-ventilated patients. Therefore we should strengthen surveillance of the causative microorganisms and their antimicrobial susceptibility. Multiple measures should be taken to prevent and treat VAP and HAP.
