摘要 目的调查重症监护病房(ICU)病原菌的分布与耐药情况,分析ICU院内感染的发生原因,探讨防治对策。方法应用法国梅里埃ATB细菌鉴定仪鉴定病原菌与药敏,用纸片扩散法加测部分药敏结果。结果ICU菌群主要以革兰阴性杆菌(74.0%)为主,铜绿假单胞菌占35.1%,肺炎克雷伯菌占11.9%,黏质沙雷菌占10.8%,葡萄球菌、粪肠球菌等阳性球菌占10.0%,真菌占16.0%,且有很大程度增加趋势。头孢哌酮/舒巴坦仍保持最高抗菌活性,亚胺培南和特治星的耐药率有大幅度上升。结论本院ICU感染主要病原菌是革兰阴性杆菌,对常用抗菌药物耐药性较高,且真菌所占比例呈增高趋势。控制第三、四代头孢菌素预防性用药,减少耐药菌株的产生,有针对性地使用抗生素是控制危重患者感染的有效措施。
