外科重症病房的菌群分布及耐药情况的变化分析

Analysis of bacterial distribution and resistance in surgical intensive care unit

目的:分析近4年外科ICU菌谱及耐药情况的变化,指导医院感染的控制及治疗。方法:对2006年1月～2009年12月外科ICU患者中957例次的阳性病原菌培养进行回顾性分析。结果:革兰阴性菌,仍占全部检出菌株的主要部分,但金黄色葡萄球菌和真菌有上升趋势;铜绿假单胞菌、金黄色葡萄球菌的耐药情况日趋严重。结论:外科SICU医生应熟知本科室内病原菌的分布特点及耐药情况,更合理地应用抗生素,减少细菌耐药,提高抢救成功率。

Objective In order to guide the hospital infection control and treatment,we analysed the bacterial distribution and resistance in surgical ICU in recent 4 years.Method From January 2006 to December 2009,there were 957 cases with sub-culture positive pathogens were retrospectively analyzed in our department.Results Gram-negative bacteria enjoyed the main part,but Staphylococcus aureus and fungi displayed a rising trends.The resistance of Pseudomonas aeruginosa and Staphylococcus aureus was getting worse.Conclusion SICU physicians should be more familiar with the distribution of pathogenic bacteria and drug resistance in their own department,in order to improve the rational use of antibiotics,reduce bacterial resistance,and improve the successful rescue rate.
